Working with livestock producers for sustainable management of carnivores The aim of this Churchill fellowship was to study techniques being used by international institutions to coexist with carnivores, for the benefit of Australian livestock producers and the environment. These techniques may help Australians to coexist with dingoes, Australia’s native wild dog, and indirectly aid in the conservation of Australian plants, animals, and landscapes by maintaining populations of a top order predator.
Outcomes of the fellowship During my fellowship I visited institutions, trusts, government and non-government organisations and individual scientists that comprise the forefront of innovative ecological research on carnivores. My major finding is that conflicting perceptions on what is ‘right’ or ’moral’ for self and earth drastically influences dingo (wild dog) management. It is a value based identity crisis between livestock producers and conservationists that neither can win because the arguments are value based, and it is critical to resolve this conflict to move forward.
Recommendations to manage carnivores sustainably Recommendations for carnivore management in Australia include: 1. Amend all state and territory legislation to provide protection to dingoes, as I defined
them by their functional ecological role in my book Dingo, to be consistent with the definition of a native animal in the Commonwealth Environment Protection and Biodiversity Conservation Act 1999;
2. Establish programs at state and federal levels to monitor dingoes more closely to identify numbers of breeding pairs (that define a pack), quantify the scale of the dingo issue and potential threats to livestock;
3. Develop management strategies based on the scientific data collected; 4. Identify and mitigate barriers to animal migration; 5. Develop a management plan to coexist with dingoes that is ecologically sustainable; 6. Educate and train livestock producers and government agencies in the use of ecologically
sustainable carnivore management techniques to minimise livestock depredation; 7. Commence scientific research to investigate differences in the ecology and behaviour of
dingoes undisturbed by lethal control and those populations disturbed by lethal control; 8. Increase community education, awareness and involvement in dingo management; 9. Establish an independent committee to review legislation, policies and management
plans involving wild dogs and dingoes; and 10. Increase collaboration with international wildlife research institutions.
Implementation and Dissemination During my fellowship I shared findings through videos distributed via electronic media. Since returning I participated at the Blue Mountains Pest Management Strategy community consultation, reviewed the draft NSW Wild Dog Management Strategy 2011/2015 (see appendix), and informed colleagues of the outcomes of my fellowship. I was interviewed for BBC wildlife magazine on defining dingoes and also ABC 630AM radio, Townsville, about management techniques for dingoes encroaching on suburbia. I will continue to disseminate my findings through publications and public speaking. I have also submitted three grant applications to implement the outcomes of my fellowship in Australia.

Preface and Acknowledgements This report was written for an audience of everyday Australians so I have chosen to include a list of recommended readings rather than using citations and references. Much of the information provided is the result of personal communication, so I will refer to the person or persons with whom I was holding discussions where possible. In saying that, I acknowledge that some ideas put forth in this report were not my own (they came from the people listed below), and that in those circumstances I am a mere messenger. I was however privileged with hours of time in lieu between destinations to ponder over concepts or to discuss these ideas with locals. First and foremost, I would like to thank Professor Chris Dickman in Terrestrial Ecology, University of Sydney and Professor Robert Mulley in Animal Science, University of Western Sydney for the tremendous support and guidance they have provided.
I would also like to thank the various institutions, government and non-government organisations, and scientists and field staff that provided me with their valuable time, experience and with the opportunity to show me and discuss various aspects of carnivore management. I do not believe any Churchill fellow can express enough gratitude to the Winston Churchill Memorial Trust for the tireless work they perform to provide Australians with a unique opportunity to pursue their goal to make a difference for all Australians. It was incredible. I pondered for hours about what it is that the selection committee looks for in successful candidates. I had been informed that my passion and motivation to find a solution to a 200-year long battle with dingoes, or wild dogs as some people like to call them, was the tipping point. But I have to say that I think the panel sees more than that. I did not only learn from the people I visited, but I shared with them my personal insights and contributed to their understanding of the issues and of the ecology of canids. The more people I met and spoke with, the more I felt that I had been selected as an ambassador for Australia. The feeling I got from knowing that the selection committee believed in me, and supported my fellowship as a representative of Australians is incredibly inspiring and motivating. It is this inspiration and motivation that I am most grateful for.

1. Introduction In every nation around the world, humans and carnivores are in conflict. The conflict ranges
widely, from foxes in the United Kingdom attacking toddlers, through to coyotes in the USA
and dingoes in Australia encroaching on urban areas. Great white sharks continue to keep
some people from swimming in the seas, and if the great whites open and close their jaws on
an unsuspecting human, calls for culling emerge despite their protection under international
agreements. Then there are ‘lions and tigers and bears’ that have scared children since before
the production of Wizard of Oz and for some reason people tend to be scared of the big bad
wolf. Who is afraid of the big bad wolf anyway? You? Have you ever been face to face with a
‘big bad wolf’? Where does your fear come from? More to the point, who started the rumour
that wolves were bad?
In some places, usually those with minimal human disturbance, some carnivores provide a
vital function for ecosystems. The function could also be deemed a structure: something that
completes the web of life and sits at the top of the food chain to regulate the animals below
that cannot self regulate their own population. Obviously carnivores would deliver the same
functional mechanism in every landscape if provided with the opportunity, but there are
guilds of carnivores and of herbivores and each guild has a different function in their portion
of the web. The web, the first world wide web that evolved billions of years before the
current ‘world wide web’, has however been fragmented following colonisation and
disturbances by humans. The relatively new concrete and bitumen shell in some places
around the earth leaves no room for normal ecological processes to occur.
The first function of carnivores is to eat herbivores that would otherwise eat too much
herbage (grass and leaves) if they were not preyed upon. The herbivores instead would
increase their population size because they have higher breeding rates, until resources were
fully consumed. Then the herbivores would probably be at higher risk to contract disease,
cause erosion and eutrophication of waterways and slowly but surely lower the productivity
of the landscape. Secondly, the highest trophic order, apex carnivores, also known as top
order predators, self regulate their own population when they compete with each other for
vital resources such as food, water, territory, protective habitat, and a mate to increase the
biological fitness of their genes. Carnivores therefore do not only keep the prey in check, but
they keep themselves in check too. This is the clearest example of natural selection, the
Sustainable management of carnivores 2010
Brad Purcell 2
survival of the fittest, the preservation of favoured races in the struggle for life. Kill or be
killed. Eat and be eaten.
This aptly named vital role (Figure 1) is evident where large carnivores for instance, have been
either reintroduced or managed to maintain their functional ecological process. Marked
differences in ecosystem health can be seen from Yellowstone National Park in the USA
where wolves were extirpated and later reintroduced, to the Mongolian deserts that once
were grasslands before wolves were exterminated, in parts of Africa that have lost their
predators and even in the arid zone of Australia where dingoes have been replaced with top
order herbivores (such as sheep, cattle, rabbits and kangaroos). The vital functional role is
however exactly what many humans protest against, because in being ‘intelligently designed’1
to kill herbivores, predators appear to be working against the grain of human based economic
schemes that have grassroots in agricultural primary production systems.

Figure 1: The vital functional role of top order predators shown through direct and indirect effects (connecting lines) in a basic version of the web of life. Top order predators affect the structure of the web through competition with middle and lower order predators. Through competition, top order predators help to save middle and lower order herbivores that middle and lower order predators prefer to prey upon. Through predation of the top order herbivores that would otherwise depredate the primary producing grasslands, the top predators provide structure and habitat for other predators, herbivores, and birds and invertebrates, and invariably maintain the health of soils.
Amongst reports from livestock producers and lobby groups that dingoes in Australia, and
wolves or other wild dogs in other parts of the world ‘killed our livestock’, and ‘are worse
than ever’ when the market value of livestock increases or decreases, it is rare to hear about
the flip side. How valuable and productive is their land? Has it already been degraded beyond
repair? Do wild animals have rights to access vital resources and enact their vital, functional,
ecological role? Who is responsible for the welfare of livestock, and of wild animals? If wolves
kill stock, is it because the wolves were not killed or because the stock was poorly managed
and/or neglected? Do dingoes kill sheep because they think there are too many of them
eating the grass and disrupting the balance?

This study was approved to learn new techniques that may help Australians to coexist with
Australia’s top order native predator, the dingo. Although genetic and archaeological
evidence have indicated that dingoes were introduced to Australia approximately 5000 years
ago, the Commonwealth Environment Protection and Biodiversity Conservation Act 1999
defines native animals in Australia as those that were present before 1400 AD. Therefore the
dingo is approximately 4401 years native! Other evidence that supports the relevance of
maintaining populations of dingoes as ecologically functional, top order predators is that the
rate of extinction for Australian mammals did not significantly increase until the introduction
and development of agricultural production systems. Such development included land
clearing and other modifications to habitat, and the introduction of domestic and wild
animals and plants. All of this information can be accessed in federal State of the Environment
Reports produced by independent scientific committees. These reports and others produced
by Natural Resource Management Boards, who may I add are often scheduled with the
destruction of ‘wild dogs’, clearly showed agricultural practices to have had significant
negative and almost irreversible impacts on Australian landscapes and their ecosystems. In
studying human-carnivore conflicts from Africa to the United Kingdom, and the United
Kingdom to Europe and then America, I hope to deliver solutions for longstanding problems
in management of dingoes, Australia’s wild dogs2, and in the management of Australian
ecological landscapes. Problems include livestock depredation and associated real or
perceived economic threats, and the degradation of ecosystems and landscapes in Australia,
including the extinction of many native plant and animal species.
2. Aims and objectives of my Churchill Fellowship
What new knowledge did I hope to gain from my project? My objective was to learn and develop proactive, ecologically sustainable carnivore
management techniques. For instance, implementing farmer compensation programs and
learning techniques to develop holistic rural community collaboration projects are two areas
that could make a difference in Australia because at the moment they are skewed to benefit
industry. Identifying how government agencies can approach controversial wildlife issues to
simultaneously achieve holistic management outcomes for livestock producers, rural
2 In submitting scientific articles for publication in international peer reviewed scientific journals, nomenclature of dingoes has been an issue for some reviewers. The issue is that if the animals are called ‘dingoes’, then public scrutiny generally condemns lethal control, but if they are called ‘wild dogs (including dingoes and their hybrids)’, then there is less public scrutiny and increased opportunity for lethal control by wildlife managers.

communities and ecological communities will benefit Australia and Australians in subtle but
relevant ways in the long term.
Why did I need to travel overseas to obtain this knowledge? Dingo management in Australia is currently in a transition phase between controlling dingoes
for livestock production enterprises and conserving dingoes for nature conservation.
Community collaboration, compensation, reserve design & novel predator monitoring and
deterring techniques have not yet been pursued in Australia. Overseas institutions have
already implemented these techniques with success.
How will my project benefit the Australian community? Many Australians may not realise but dingo/wild dog control is a major cost to taxpayer
money. From 2007-2008, $9.5 million was spent on dingo control in Australia. Furthermore,
Australia's national sheep flock that comprised 170 million head in 1990 has declined
dramatically to 76.9 million head in 2008 due to market fluctuations. Despite the diminishing
industry and identified threats of climate change to food production (or vice versa), rural
communities continue to perceive dingoes as the problem. By introducing techniques to
minimise livestock losses and increase employment opportunities, financial and social aspects
of rural community industries may be maintained. Not only may the rural communities
benefit, but also so may fragile Australian ecosystems. Experts agree that dingoes may
outcompete and prey upon introduced species, such as foxes, cats, goats and pigs that have
exacerbated native mammal extinction. Living with a keystone species like the dingo is
important to lessen or reverse the Australian extinction crisis and to assist regeneration of
degraded Australian landscapes, such as the Murray-Darling Basin.
3. Programme 30 June – 27 August 2011 The program scheduled for my Churchill travel fellowship included visits to:
Wildlife Conservation Research Unit: University of Oxford, United Kingdom
The Wolf Centre: Combe Martin, United Kingdom
Polish Academy of Sciences Mammal Research Institute: Białowieża, Poland
Defenders of Wildlife: Idaho, USA
Yellowstone National Park: Wyonming, USA
Sustainable management of carnivores 2010
Brad Purcell 6
Yale Large Carnivore Group: Wyoming, USA
Each organisation and their program are described below.
Botswana Predator Conservation Trust: Okavango Delta 30 June – 15 July Dr John ‘Tico’ McNutt founded the Botswana Predator Conservation Trust (BPCT) as the
Botswana Wild Dog Research Project in 1989. The camp is highly regarded amongst carnivore
ecologists and is one of the longest running conservation research projects in Africa. African
wild dogs are listed as endangered with a decreasing trend on the IUCN Red List of
Threatened Species. Visiting the BPCT was important because they had conceived the idea of
talking to the African wild dogs in the language of wild dog scent markers to deter them from
properties with livestock. Known as the bioboundary, this technique will hopefully one day be
used to mimic the borders of an African wild dog pack. In repelling or deterring African wild
dogs from crossing that boundary, the BPCT expect to successfully stop livestock depredation
events by African wild dogs and stop the lethal control of African wild dogs for long term
conservation of this species.
Wildlife Conservation Research Unit: University of Oxford 18 – 21 July The Wildlife Conservation Research Unit is based in the Department of Zoology at the
University of Oxford. The WildCRU scientists are renowned world experts in carnivore
ecology. I was interested in the expert opinions of the chief scientists, the doctoral and post-
doctoral research candidates, and in the environmental sustainability training programs that
they run for rural pastoralists in developing countries. In addition, WildCRU houses and
provides support for the IUCN Canid Specialist Group (CSG) that is also part of the IUCN
Species Survival Commission.
The Wolf Centre: United Kingdom 22 July The Wolf Centre is an education facility to teach people about behaviours of wolves and of
domestic dogs. To develop a unique understanding of wolves and wolf behaviours, Shaun Ellis
lived with wolves for two years, learning how to communicate with them, sharing their food,
and living by their rules. My interest was in learning potentially abstract concepts that are not
available from everyday scientists, and hearing Shaun’s views on wolves from living amongst
them.

Brad Purcell 7
Mammal Research Institute: Polish Academy of Sciences 25 – 29 July Białowieża Primeval Forest is a remnant lowland deciduous temperate forest ecosystem that
was originally conserved as an area for hunting by monarchs and dignitaries and it is reserved
as part of United Nations Educational, Scientific and Cultural Organisation Man and Biosphere
reserve system. The Mammal Research Institute of the Polish Academy of Sciences studies all
aspects of mammalian biology and interactions with the forest and surrounding areas. My
interest in wolf management at the MRI was in relation to the use of migratory corridors to
maintain ecological connectivity for wolf migration. In providing movement corridors, wolves
and other animals can maintain genetic variability and reduce the risk of a genetic bottleneck
within metapopulations.
Defenders of Wildlife: Idaho, USA 8 – 14 August Defenders of Wildlife use science-based, results-oriented management strategies and policies
for wildlife conservation. In Idaho, Defenders of Wildlife work alongside livestock producers
to facilitate holistic landscape management and wolf conservation. Defenders of Wildlife
implement various proactive wolf management programs to minimise livestock depredation
by wolves, and community education programs to reduce tension with producers. These
include compensation programs to reimburse livestock owners for their losses in the event of
wolf predation, promotion of acceptable science based wolf restoration plans and
collaborating with livestock producers on advisory boards to determine and understand the
issues and develop suitable management practices. The program I went to learn about was
the Wood River Proactive Project. The goal of the project was to reduce livestock losses to
wolves using various non-lethal tools and techniques. With a focus on increasing tolerance by
livestock producers to wolves, Defenders hope to reduce conflict and maintain or increase
productivity.
Yellowstone National Park: Wyoming, USA 15 – 21 August Yellowstone is the world’s first national park, established on 1872. Gray wolves were
reintroduced to Yellowstone National Park to reverse the impacts of large ungulates on the
landscape. This week in the fellowship was relatively unplanned because I wanted the
freedom to explore various aspects of wolf recovery, and management of the oldest national
park on earth. In studying top order predators it is important to assess the entire ecosystem,
rather than the species itself, to gain insight for effective management plans.
Sustainable management of carnivores 2010
Brad Purcell 8
Yale Large Carnivore Group: Wyoming, USA 22 –27 August
Visiting the Yale Large Carnivore Group will be of benefit during my fellowship because their
goal is to facilitate coexistence between people and carnivores. They deal directly in practical,
cultural, and ecological areas through researching policies, and political and economic
processes. Conservation efforts cannot ignore those aspects and the specific social contexts
within which they occur. Successfully addressing these human dimensions depends on our
ability to find creative ways to protect species in sustainable ways through an inclusive,
participatory process with people who live and work in carnivore habitat. When I visit Jackson
Hole I will work mainly with Professor Susan Clark from Yale University.
4. Outcomes of my fellowship It was overtly evident from my fellowship that there are numerous and various techniques
that will help Australians to coexist with dingoes. These techniques may also be cheaper,
more cost effective to implement, and benefit both livestock producers and Australian
ecosystems. During my fellowship I participated in science and applied science, desktop
research, abstract conceptualisation, international natural resource management programs,
and spoke with people from international education organisations and committees that
review, produce and disseminate international policies for protection of natural resources.
Management of wild dogs around the world in general is entering a new phase because the
benefits of their conservation are so visible since wolves were reintroduced to Yellowstone
National Park. One of my major observations is that although Australians have started to
make progress we are probably 30 years behind other countries. One of the most prominent
pieces of legislation for wild dogs in NSW, the Wild Dog Destruction Act 1921 is too old to
have any meaning in degraded Australian landscapes of 2011 so this act should be abolished
and replaced with an act that is suitable for the 21st century.
I also observed that many of the issues that Australian livestock producers and natural
resource management organisations face are prominent in the nations I visited. The threat of
predators to prey will never go away, nor will the battle between competitors for prey. A
grizzly bear fending off wolves from a carcass is no different to farmers fending off criticism of
their inherent right to do what they want with the lands that their fathers’ fathers have
handed down. And suddenly we are at the crux of the issue. Two different groups with
Sustainable management of carnivores 2010

opposing perceptions on what is ‘right’ or ’moral’ for self and earth, arguing over an identity
crisis.
Botswana Predator Conservation Trust: Okavango Delta The Botswana Predator Conservation Trust provided insight into numerous and various
aspects of carnivore ecology, behaviour, research and management. In addition I learnt a
great deal about vehicle maintenance and management of a research station. Most of my
time at dog camp was spent conducting research with the various scientists. Each day we
would check for VHF telemetry signals from lions, cheetahs, leopards, hyenas and African wild
dogs fitted with VHF telemetry transmitters and our movements were often dependent on
those signals … or lack thereof. In the case of lions and leopards, the scanning also played a
role in camp safety. If signals were not detected then we would drive 20 minutes to a tourist
camp to look for the signals again and hope that along the way we either crossed paths with
the individuals we were looking for or detected a signal to follow. One morning in fact, we
crossed paths with three African wild dogs that were approximately 60 km away from their
territory hunting (Figure 2).
Figure 2: African wild dogs hunting approximately 60 km outside their known territory. The dog in the middle has a beige collar around its neck.
I was surprised in Africa that we could drive within 10-15m of the animals to make
observations (Figure 3). In Australia the dingoes would run at the sight of a vehicle 100m
away, and I have even watched some dingoes leave an area at the sound of a vehicle. Much
of my time was therefore spent at den sites, filming and photographing pups to determine
Sustainable management of carnivores 2010
Brad Purcell 10
how many pups were born in each pack, and to identify individuals where possible. The white
markings on wild dogs apparently are the only consistent markings that do not disappear with
age, and recording the white markings is a reliable technique for future identification and
population monitoring. Identifying individuals may be a little more difficult this year than
other years, however, because one pack had 11 pups, with large amounts of white markings
on most of them (Figure 4). We visited this pack a few times over the two weeks and on one
occasion when postdoctoral researcher Dr Neil Jordan joined us, I was able to see how
samples are collected for the bioboundary research project. Basically a female urinated when
we approached the den site so Dr Jordan parked the car between the den and the urine. He
cautiously got out of the car, and collected the sample for later testing in the laboratory.
Figure 3: African wild dogs resting near the den in between feeding the pups.
Figure 4: Two African wild dog pups, showing one side of their unique white markings that were being recorded.
Counting the pups was also a hard task because we could never be fully certain that all of the
pups had emerged from the den. On one occasion we arrived at a den site with one individual
Sustainable management of carnivores 2010
Brad Purcell 11
adult male sitting near the entrance. Within five-minutes, the female returned to the den site,
greeted the male, entered the den and picked up a pup, and then walked back in the
direction she had come from with the pup tittering in her mouth. We watched her move her
offspring and the following day we found her new den site and continued to monitor the
pups. Why she moved the pups however is one of those questions that we may never have an
answer to.
A short time later the adult wild dogs suddenly left the den and went hunting. We followed
them as best we could but as the dogs moved so quickly, we could only get brief glimpses of
them threatening prey and testing prey for weaknesses. Life in dog camp was much like this
each day, providing various opportunities to collect data. For instance, some lions had found
a carcass from a large bull elephant so we went to identify the lions and record any necessary
information (Figure 5).
Figure 5: Three lions in Moremi Game Reserve, Okavango Delta, resting by an elephant carcass.
Whilst in the Okavango Delta I was also witness to some incredibly rare events. For instance,
on one occasion when I was working with the cheetah researchers, we saw the first two
rhinos to recolonise the Okavango. Tico, the founder of the African wild dog research project,
had never seen rhinos in the Okavango, and he has been conducting research in the area for
more than 20 years. On my last night I saw a male and a female leopard interacting, which
was considered rare by the other researchers.
Sustainable management of carnivores 2010
Brad Purcell 12
Then there was the event with cheetahs. Doctoral candidate Femke Broekhuis who was
studying interactions between cheetahs, lions and hyenas was finalising her research project
at the time, and retrieving collars from each of the species. The first cheetah that she darted
was a female with a cub. Whilst mum was sedated, the cub continued to call for her and
started to slowly wander off (Figure 6). I was in the car responsible to monitor the safety of
the cub from lions or other predators and was shocked when the cub started to run and two
large male cheetahs suddenly arrived on the scene in pursuit of the cub (Figure 6). The first
thought that came to mind was infanticide, where the males were going to kill the cub to
reduce genetic competition. I impersonated a cub calling for its mother by whistling that
distracted the males for a moment, but we still could not see the cub moving. We finally
found the cub alive, sitting about 10m from the males. Apparently most reports of infanticide
amongst cheetahs are anecdotal and other research has indicated that the males want to use
the cub to meet the mum. This was the case on this occasion when mum arrived, the males
quickly knocked her to the ground and asserted their dominance.

cub (bottom right).

One of the males was then successfully sedated and its collar was replaced with a new one.
After successfully administering the reversal agent, the researchers starting the next study
realised that the VHF was not transmitting a signal and they were forced to sedate the male
again, but this time with Zolatil instead of Ketamine. Waiting for the Zolatil to reverse in
cheetahs is a six-hour process, so we had to wait in the area and scan for lions or other
competitors until 11PM. Even then, two researchers remained with the cheetahs until
daybreak when the cheetahs moved out of the area and disappeared in the morning light.
Whilst retrieving data from motion sensing cameras used at cheetah scent marking trees, I
was informed that after scientists had discovered the use of scent trees and reported their
results, livestock producers waited at those trees to kill the cheetahs. That dilemma and
others I experienced with darting the cheetahs, almost losing a cub and having to sedate one
cheetah twice makes me wonder when science and the resources to implement a study
outweigh the welfare of the animals. Researchers have discovered that dingoes trapped for
their study in Queensland had been suffering from foot necrosis (the premature death of cells
and living tissue), possibly due to lost blood circulation in the foot as a result of being
trapped, after they had killed the dingo to retrieve the data-logging collar. Tico had been
informed of this technique, and was laughing at the situation when he asked if I was the
researcher that kills the animal to retrieve the data. I informed him that I was not and that it
was common practice for Australian scientists to kill dingoes and wild dogs to retrieve results,
such as stomach contents and skulls for testing ‘purity’. At that moment, I felt ashamed that it
is an accepted practice in Australia.
After finishing my fortnight at dog camp, I was taken to the lab to discuss the biochemical
analysis component of the project. Dr Peter Apps showed me the gas chromatography - mass
spectrometry machine and described the results (Figure 7). The machine is not yet accurate
enough to detect all of the chemicals that the nose of a dog would be able to, but it is all that
is currently available for use. In addition, after detecting the markers, they need to be trialled
on wild dogs in the field to find out which marker tells other dogs to ‘keep out’ of an area.
Peter and his assistant have identified over a hundred compounds in the odours of wild dog
urine and faeces and have discovered differences between urine deposited at different
places, at different times, by different packs, and by different dogs within a pack. Now it
appears to be a problem of identifying which chemical patterns form the territorial signal
rather than which individual chemical sends the information. They have identified similarities
in chemical composition within packs, and differences in dominant animals between packs.

Wildlife Conservation Research Unit, University of Oxford: United Kingdom Upon arriving at WildCRU, I met with Professor David Macdonald (Figure 8). Professor
Macdonald is also a Churchill Fellow so we spoke briefly about the fellowships, and other
research endeavours. At the time, David was busy advising the government about a push
from the farmers lobby to cull badgers, to decrease the chances of a tuberculosis outbreak.
Twenty years of badger studies showed that killing them was very negative and one of the
effects of lethal control on badger populations was increased prevalence of dispersal and
wider ranging movements. The threat of tuberculosis being spread therefore also increased.
In addition, more types of tuberculosis develop in fragmented badger populations living in
perturbed conditions, making the disease harder to control. Despite the evidence and expert
advice, the government announced it would proceed to control 150,000 badgers.

Figure 8: Meeting Professor David Macdonald (left) and Professor Claudio Sillero (Right) from the
Wildlife Conservation Research Unit, Department of Zoology, University of Oxford.
The next day I provided the WildCRU a presentation about my research on Australian dingoes
and everybody seemed quite impressed. Dr Chloe Strevens informed me that it covered the
interests of both Professor Macdonald and Professor Claudio Sillero (Figure 8), being
movement patterns, territory maintenance behaviours and dispersal behaviours. Professor
Sillero and I had a lengthy discussion about our research projects and canid management. We
discussed the effect of dingo/wild dog control in Australia and I suggested that it might
exacerbate the problems. I informed him that dingo researcher Dr Lee Allen has made
observations consistent with this hypothesis. Professor Sillero agreed and stated that it took
six years for pack stability to return following a rabies outbreak amongst the Ethiopian wolves
that he was studying. In terms of animal welfare, I informed Professor Sillero about the
observations of foot necrosis, and he advised that their traps are checked every two hours to
avoid adverse psychological and physical effects to the Ethiopian wolves. If dingo populations
are similarly effected, then dingo/wild dog management strategies should be reviewed to
avoid adverse psychological and physical effects.
Professor Sillero and I also discussed the effects of phenotypic plasticity (response of animals
to environmental conditions through both genetic and physical change within one
generation) and the effects on taxonomic classification of canid species. He advised that as
chair of the IUCN Canid Specialist Group, he is frequently requested to revise the taxonomic
status of some canid species. Based on recent evidence that indicates skull allometry,
phenotype and genetic population structure can vary dramatically based on environmental
conditions, he considers that he cannot approve such requests. If such requests were
approved, it may permit animal breeds to be classed as their own species. In my opinion, that
Sustainable management of carnivores 2010
Brad Purcell 16
should not be permitted because such breeds have not formed under natural evolutionary
circumstances, they have instead been bred because they exhibit traits that interest some
people. In dingoes, those traits look like four white paws, a white tail tip and a tan/ginger
coat. It is therefore not surprising that opinions of what is a ‘pure’ dingo are so strongly
formed amongst Australians. The definition of a dingo is an issue in Australia because the
terms ‘hybrid dingoes’ and ‘wild dogs’ are used as leverage for lethal control, and that is why I
defined dingoes in my book (Purcell, 2010) by their functional ecological role and one annual
breeding cycle.
I had a similar interesting conversation with Dr Nobuya Suzuki. Dr Suzuki hypothesises that
such arguments to kill or conserve are value based, like the concept of conservation and the
business of livestock production, and nobody can win value-based arguments because they
are value based. There is no good or bad. There is no right or wrong. There is majority against
minority or a winner and a loser. I considered these concepts themselves require exploration
in Australia because winning and losing are based on perceptions. Dr Suzuki suggested that in
this case it is a battle of human rights against conservation and conservation will always lose,
even if the mindset of the conservationists is to assist humans in the long term. Dr Suzuki
highlights the need for livestock producers and conservationists in Australia to work together
to achieve a common goal. That goal being improved landscape productivity and biodiversity
through the sustainable management of carnivores.
Other key issues discussed by researchers at WildCRU included:
One researcher has walked 2500 km surveying for lions in central West Africa and
only found two.
Kenya Wildlife Service considers lions may be extinct in 10-15 years.
Leopard destruction permits in parts of Africa are awarded on little evidence and
solutions to mediate the problem relevant to dingoes include inspecting depredation
events within 24hrs, identify and destroy the individual animal that caused the
damage and work with farmers to improve herding techniques.
A better understanding of hunting techniques is required to manage large carnivores
more efficiently and holistically.
Environmental stewardship program similar to those implemented through WildCRU
could be used in Australia to maintain and increase biodiversity in rural areas through
incentives.

The Wolf Centre: United Kingdom Shaun Ellis at the Wolf Centre spoke of some very unique concepts and observations that he
learned during his time living with wolves. Contrary to popular opinion that science is the only
methods to make accurate observations, Shaun believes that to fully understand wolves, he
had to become a member of the pack. This was what enticed me to meet him – he was
different. I had already visited and would continue to visit research scientists that used
traditional methods to collect quantitative data for analyses and considered that my
fellowship may benefit from hearing his views.
Shaun had made observations of diet, pup development and training, howling, predation and
territory defence that I had not previously heard other scientists discuss (Figure 9). In terms
of diet, Shaun believes that prior to whelping or early nursing season, the wolves turned to a
milk based diet, such as calves. One observation relevant to the bioboundary technique, is
that Shaun believes the wolves will chase prey to maximise the release of adrenalin and
endorphins that change the flavour of the flesh and organs. Once consumed, these flavours
or odours become the chemical cues in scent marks. Another was that the dominant animals
wait behind the subordinates to watch the reaction of the prey or competitor and avoid
injury.
Figure 9: Shaun Ellis, the man who lives with wolves, explaining behaviours of wolves whilst they fed on a carcass, Combe Martin, UK.
On discussing the hierarchy of wolves, Shaun believes wolf packs have a decision maker, an
enforcer, a tester, a ‘numbers’ animal, a lookout and a nanny, hunters and an omega animal.
This system helps maintain pack mentality and stability and creates circles of development
teaching (cultural transmission) for juveniles. Fragmenting the system may cause
Sustainable management of carnivores 2010
Brad Purcell 18
perturbations similar to those reported for badgers, and for dingoes in north west Western
Australia by Peter Thomson in the 1990’s.
In terms of management, Shaun stated that programs should be adjusted year to year and
even season to season to account for variations within the pack. For instance, locating,
rallying, defensive and recruiting howls could somehow be used to manage movements of
individual wolves. Howling assists in maintaining territory borders, along with scent marks
and sight when the competitors prepare for conflict at the final stage. Attacks on livestock or
other prey species are seasonal amongst wolves and dependant on the age of the pups, so
land and wildlife managers and livestock producers simply need to adapt their management
at those times. I demonstrated in my dingo research that there were seasonal variations in
diet and in movement patterns of unperturbed dingo populations, which may assist
Australian livestock producers in reducing stock depredation.
Mammal Research Institute, Polish Academy of Sciences: Białowieża, Poland Professor Włodzimierz Jędrzejewski whom I had contacted about visiting the MRI is currently
working on Jaguars in Venezuela, however, he was in Poland on the 24th July, when we had
scheduled to meet. British Airways had overbooked their flight to Poland, and when I arrived
there were no seats left available on the plane. Unfortunately, due to this delay I missed the
opportunity to meet with Professor Jędrzejewski.
Research by Professor Jędrzejewski and other scientists at the MRI revealed that forest
corridors are a necessary component in any conservation program for wolves because wolves
have large territory sizes and are predisposed to disperse if conditions are not favourable, or
if mates are not available. Negative impacts of man made structures such as roads and
railway on habitat and animal populations can be minimised and mitigated using
underpasses, overpasses, signage for awareness, and through a better understanding of types
of movement patterns.
For this aspect of my fellowship, I was provided a book written by Professor Jędrzejewski and
others titled Animals and roads: Methods of mitigating the negative impacts of roads on
wildlife. After I read this book, I came to the realisation that roads and railway lines in
Australia have severely fragmented habitat and populations of animals. This is not a new
observation, because I had previously studied habitat fragmentation as an undergraduate and
Sustainable management of carnivores 2010
Brad Purcell 19
have seen examples in New South Wales, Australia, where the Roads and Traffic Authority
(RTA) have attempted to maintain habitat connectivity. Now I realise that they have not done
enough. For instance, think of the freeway between Sydney and the central coast. There are
bridges and opportunities for animals to walk under the roads using underpasses. What if,
however, there were animals that have movements limited to ridgetops? The characteristics
of underpasses and overpasses may also deter animals from using them. There was a strong
relationship for instance between the width of an overpass and the frequency of use by
animals. Habitat availability on an overpass may also deter or encourage animals to use the
passage. During discussion with the spatial scientists at MRI, I showed them the Australian
road network in Google Earth and searched the RTA website for information on animal
passages and crossings. Admittedly my search was not comprehensive but there appeared to
be a lack of information on the subject. Some reports had briefly mentioned the issue and I
am aware of fences used to deter animals such as koalas from attempting to cross roads
between Buladelah and Port Macquarie. Opportunities for dispersal and migration should
either be maintained or where possible, increased and not prevented. Wolves have however
managed to start dispersing without habitat connectivity in Poland, but the lynx have not.
One wolf being studied travelled 1500 km from East Germany, across the top of Poland to
Białowieża Primeval Forest and Belarus before the tracking collar failed or the wolf was killed
(c.f. www.polishwolf.org.pl).
At the institute I gave a presentation on my dingo research to staff and students. Once again
it was well received and some researchers confirmed my ideas associated with genetic
population structure, diet and patterns of movement. Other scientists at the Mammal
Research Institute such as Dr Krzysztof Schmidt, Deputy director of the Mammal Research
Institute and Thomasz Borowik, PhD Candidate, provided me with some very relevant insights
of studies that will contribute to understanding wolves. These included:
- Looking at the stress levels between ungulates in areas where wolves have
recolonised, have not yet recolonised and are currently recolonising;
- What is the perception of prey to predator and reactions of prey to scent of
predator; and
- Interference of humans with large carnivores because conservation goals
interfere with development of the country.
Conflicts however continue to arise. There is a compensation system in Poland that is not
working effectively due to administrative requirements to be awarded compensation.
Sustainable management of carnivores 2010
Brad Purcell 20
Farmers prefer no predators and no problems and although depredation events are generally
local, some farmers make a lot of noise and exacerbate the scale of the problem. To conserve
the wolf in that sense it is acknowledged that some wolves need to be shot, especially since
some farmers believe that the government regards wolves to be more important than them.
Illegal hunting is another dilemma that can be managed by permitting wolf hunting but then
the wolves are still being killed and conservationists have to carry the burden of that sacrifice.
Similar to Australia, wolf management strategies in Poland may allow for shooting (or control)
to occur so that political tension between the government and the public is suppressed.
Polish scientists have observed that the wolf population is not increasing in areas where they
are not hunted as much as in areas that they are hunted.
In terms of connectivity there are trends showing that wolves living in bigger forests with less
fragmented habitat are not as big a problem as wolves living in fragmented habitats. The
connectivity is crucial to species longevity and genetic population structure. The MRI
scientists are very interested in dispersal related problems because they are linked to genetic
variability and therefore population strength of the species. Dr Matt Oliver, postdoctoral
fellow in genetics at the MRI, had other interesting insights into population genetics. In terms
of function he considered that dilution of genetic structure through hybridisation will make
matters worse, though contends that genes will be purified by natural selection in the wild. I
have hypothesised that natural selection may play a bigger role in dingo populations to revert
back to a ‘dingo like’ functional state, regardless of the extent of hybridisation. I raised this
possibility at the 15th Australasian Vertebrate Pest Conference in Sydney, 2011.
When I enquired as to our ability to coexist in the future with wolves or predators in general,
the response from MRI scientists was not overly optimistic and survival was dependant on
how the world develops . The distribution of humans, roads and habitats limits the
opportunities for predators and more roads will lead to more cars, and more people. It is
most important to document change because adaptation of predators to human settlement
may lead to new problems. The wolf population in Europe increased during periods of war
because they could scavenge human corpses, and then crashed again in the 1970’s.
In Poland, farmers are responsible for reducing the risk of livestock depredation and their
livestock should be put into safe zones at night to prevent attacks. In contrast, wolves will kill
one cattle beast per attack but they will kill numerous sheep packed tightly into a protected
fenced area. Wolf predation in Poland also changes seasonally and damages are most
Sustainable management of carnivores 2010
Brad Purcell 21
pronounced in September/August when wolf pups become more active simultaneously with
the time of year calves are born. This is consistent with observations of wolves turning to a
milk based diet such as suckling calves by Shaun Ellis, in whelping/early nursing seasons.
Whilst in Białowieża I participated with the MRI in tracking a Eurasian lynx (Figure 10), and
was taken to see the guarded Białowieża Primeval Forest (Figure 11). During a meeting with
Dr Andrzej Zalewski, Director of the MRI, I was once again humoured by comments such as
‘only in Australia they use poison!’ Dr Zalewski’s background is the ecology and conservation
of carnivores, and he is of the opinion that genetics should be used to identify barriers to the
dispersal of invasive species, and the distance of dispersal. When planning migratory paths
that will intersect human infrastructure, it is important to first understand species habitat
selectivity, the density of prey species along the roads, and the density of preferred prey
within or adjacent to the migratory corridor.

Defenders of Wildlife: Idaho, USA The Defenders of Wildlife proactive wolf management projects are lead by Suzanne Stone,
who has been involved with wolf restoration since 1988 and assisted with the reintroduction
of wolves to Yellowstone National Park. My time with Defenders of Wildlife in the Sun Valley,
Ketchum, Idaho included two community consultation days (Figure 12), wolf population
monitoring (Figure 13), and an evening of livestock protection. Since 1998, the Defender of
Wildlife organisation has spent approximately USD $1 million on proactive carnivore
management using non-lethal measures to prevent conflict. Australia spent AUD $9.5 million
during the 2007-2008 financial year on lethal control of dingoes/wild dogs.

Figure 13: Tracking a wolf pack with Defenders of Wildlife staff Matt Furber (centre) and Pete Haswell (right) in the Sun Valley, Idaho USA.
I also attended the premiere of The phantom wolves of Sun Valley – a documentary on the
conflict between livestock producers and the Phantom Hill wolf pack that colonised the area
north of Ketchum. The documentary highlighted many of the same issues associated with
human-carnivore conflict. It also showed that the situation in America is more dynamic than
Sustainable management of carnivores 2010
Brad Purcell 23
in Australia because hunters see other wildlife as a resource. Therefore it is not only the
livestock producers that feel threatened, the hunters feel like they are also threatened
because the wolves have caused the deer to seek protective cover and they are now behaving
more cautiously.
The American livestock producers are in a different situation compared with Australian
livestock producers because wolves are not the only large terrestrial predator like dingoes in
Australia. American producers also have to be cautious about depredation by cougars, bears
and coyotes. Admittedly dingoes have smaller home ranges than wolves and there is high
overlap between preferred habitat for livestock and preferred habitat by wolves. In addition,
native prey species preferred by wolves also share habitat with livestock, and they may
attract wolves into livestock habitat.
During the week, I worked alongside field staff to monitor the movements of wolves,
participate in discussions at community consultation events and contributed my expertise on
dingo ecology and management for application in wolf habitat. Defenders of Wildlife field
technicians were equipped to monitor packs of wolves and also equipped with wolf deterrent
devices. The devices included fladry tape, to set up as a fence to contain and protect sheep
during the night and cracker shells, radio activated guard boxes, air horns and radio telemetry
equipment. If wolves were present near the sheep the field staff would camp with the sheep
and monitor the proximity of the wolves to the herd. In addition they trained sheepherders in
the use of non-lethal wolf deterrents, and Great Pyrenees guard dogs were present amongst
the sheep to warn of approaching predators (Figure 14). The Great Pyrenees dogs are
probably twice the size of a dingo, and I cannot imagine a dingo attempting to fight one. As
dingoes are more nervous than wolves, I have confidence that all of the proactive sustainable
carnivore management techniques being used by the Defenders of Wildlife will work in
Australia successfully on dingoes. Furthermore, the program has been so effective that wolf
depredation on sheep has almost been eliminated. Australian livestock producers are still
suffering depredation events despite regular bi-annual baiting and reactive trapping control
programs.

Yellowstone National Park: Wyoming, USA Ecologists were discussing the reintroduction of wolves to Yellowstone National Park since
the 1970’s. It was apparent that elk were overgrazing and damaging seedlings and trees,
heavily impacting on the ecology of the park and had to be managed. Approximately 20 years
later, Canadian wolves were released, and in less than 10 years, the health of the ecosystem
had improved.
I first visited the Grizzly and Wolf Discovery Centre in West Yellowstone. I also visited Rick
McIntyre in the Lamar Valley as he has the VHF telemetry equipment and expertise to track
wolves. . Mr McIntyre is a biological technician for the Yellowstone Wolf Project and has
tracked wolves for more than 3000 days consecutively. He was the point of contact to follow
the wolves in the valley and managed the wolf watchers, those tourists and devoted locals
that regularly tracked wolves living in the park (Figure 15).

Dr Halfpenny was the next expert that I met. He has written over 25 books and videos and he
runs educational programs about natural history and ecology through A Naturalist’s World
(www.tracknature.com). Dr Halfpenny provides the public with comprehensive field guides so
that they can understand some aspects of the ecology of Yellowstone quickly and effectively.
When I visited the Hayden Valley I was lucky to arrive at the same time five wolves were
crossing the river to feed on a bison carcass (Figure 16). Here I met Bob Landis, wildlife
documentary producer and he spoke about his experiences with the wolves in Yellowstone.
Mr Landis informed me that the stories were documented on his videos. It was clear from
viewing the videos that they have documented behaviours previously unreported, which
suggests that as yet we do not fully understand the ecology and behaviour of wild wolves.
Australians therefore cannot expect to understand the impact that lethal control programs
have on dingo populations without the appropriate scientific studies.

Yale Large Carnivore Group: Wyoming, USA On my visit to the Yale Large Carnivore Group, Jackson Hole I met Professor Susan
Clark. Professor Clark’s expertise is in development of policy, leadership and
leadership perspectives and political psychology. She stated that it was important to
find common ground and to achieve this I will need to explore community interaction,
perceptions, education and values.
During the week I met with a range of experts including:
Sustainable management of carnivores 2010
Brad Purcell 26
Mike Jimenez, Wyoming Project leader, U.S. Fish & Wildlife Service Wolf recovery
program;
Jason Wilmot, Executive Director, and Rebecca Watters, Project Manager, The
Northern Rockies Conservation Cooperative;
Erik Cole, Wildlife Biologist, U.S Fish and Wildlife Service National Elk Refuge;
Gary Harvey and Dave Cottle, Bridger-Teton National Forest, United States
Department of Agriculture Forest Service;
Louise Lasley, Public Lands Director, Jackson Hole Conservation Alliance; and
Chris Colligan, Wyoming Wildlife Advocate, The Greater Yellowstone Coalition.
Mike Jimenez informed me that his role in wolf management is to maintain the middle
ground between American livestock producers and environmentalists because people like to
see wolves from their own perspectives. His aim is to ensure management plans are based on
science and a consensus of opinions so that perceptions and values are not included as part
of the plan. This is the middle ground I have been trying to achieve in Australia. By calling
dingoes ‘wild dogs’, ‘hybrids’ or ‘pure dingoes’ based on biased scientific data, perceptions
and values of livestock producers and dingo breeders are supported and dingoes are not
being managed holistically. If wild dogs, hybrids and pure dingoes are simply called ‘dingoes’
then we can start to manage them for their functional ecological role in Australian
landscapes.
Jason Wilmot and Rebecca Watters informed me that even when livestock producers receive
compensation they remain upset about the situation. It demonstrated to me that money
does not fix the situation. Erik Cole at the National Elk Refuge informed me that the numbers
of elk in their refuge each census is well above quota. It would appear that elk have instead
found areas where they are safe from hunters and predators. This is relevant because hunters
are claiming wolves have killed the elk and as a result, none are available to be hunted. In
discussing livestock management strategies with Gary Harvey and Dave Cottle at Bridger-
Teton National Forest, they suggested that if programs are not already in place, Australia
might benefit from developing vegetation management programs for livestock producers.
During meetings with Lousie Lasley and Chris Colligan we also discussed the development of
migratory corridors for protection of wildlife.

I also attended a public forum on the Wyoming Gray Wolf Management Plan (Figure 17). The
objective of the plan is to maintain a population size of at least 15 breeding pairs, and at least
150 wolves in the entire state of Wyoming. Similar to Australia, the debate was heated and
issues were not fully resolved.

5. Recommendations, implementation and dissemination
Key recommendations to work with livestock producers for sustainable management of
carnivores include:
1. Amend all state and territory legislation to provide protection to dingoes, as I defined
them by their functional ecological role in my book Dingo, to be consistent with the
definition of a native animal in the Commonwealth Environment Protection and
Biodiversity Conservation Act 1999;
2. Establish programs at state and federal levels to monitor dingoes more closely to identify
numbers of breeding pairs (that define a pack), quantify the scale of the dingo issue and
potential threats to livestock;
3. Develop management strategies based on the scientific data collected rather than using
anecdotal information;
4. Identify and mitigate barriers to animal migration to maintain genetic variability;
5. Develop a management plan to coexist with dingoes that is ecologically sustainable;
Sustainable management of carnivores 2010
Brad Purcell 28
6. Educate and train livestock producers and government agencies in the use of ecologically
sustainable carnivore management techniques to minimise livestock depredation;
7. Commence scientific research to investigate differences in the ecology and behaviour of
dingoes undisturbed by lethal control and those populations disturbed by lethal control;
8. Increase community education, awareness and involvement in dingo management;
9. Establish an independent committee to review legislation, policies and management
plans involving wild dogs and dingoes; and
10. Increase collaboration with international wildlife research institutions.
During my fellowship I maintained a fortnightly blog (www.thedingotracker.blogspot.com),

Since returning from my fellowship I participated at the Blue Mountains Pest Management
Strategy community consultation, reviewed the NSW Wild Dog Management Strategy
2011/2015 (see appendix) and provided comments to relevant government departments to
consider. I have also met with colleagues to inform them of the outcomes of my fellowship. In
addition I was interviewed for a story on defining dingoes in the BBC wildlife magazine and on
ABC 630AM radio, Townsville about management techniques for populations of dingoes
encroaching on suburbia. I will continue to disseminate and implement my findings through
publications and public speaking where possible. I will also distribute my fellowship report to

31 October 2011 Draft NSW Wild Dog Management Strategy Dear Mr Cutter, I have reviewed the Draft NSW Wild Dog Management Strategy and write to inform you that it is heavily biased, environmentally unsustainable and should be either re-written or discarded. The subject matter is too controversial to treat lightly, especially in respect to evidence that shows the functional ecological role top predators play in unregulated ecosystems. Whether your organisation disagrees with the most recent science or not is irrelevant. The science is available for reference and should be included within this management strategy to objectively create a framework for wild dog management that is holistic and employs the five objectives of ecological sustainable development. Furthermore, there are many incorrect statements, unsubstantiated claims and extensive reference to anecdotal evidence. Chapters eight and nine in my recently published monograph, Dingo (CSIRO Publishing 2010) has many environmentally sustainable management techniques that could be utilised in this strategy and I recommend you incorporate some of them into the NSW Wild Dog Management Strategy. If you would like to consult with me on this strategy, please feel free to call me on (02) 4570 1648 or 0403 492 148, or email [email protected]. Yours sincerely,
