Contrasting Restoration Efforts
on the
Fraser and Columbia Rivers The Fraser and Columbia are the two largest watersheds
in the PNW, together draining 343,000 sq. miles. TheFraser is noted for its sockeye runs; the Columbia was
noted for its chinook runs (historically producing morechinook, coho, and steelhead than any other river in theworld)
Restoration efforts on the Fraser emphasized scientificresearch on migration routes, etc. while refining counting
methods, but science was given low priority on theColumbia, where dams were built and money was putinto hatcheriesan example of American techno-optimism(Lichatowich, 1999)

Results of Salmonid Restoration Efforts
on theFraser and Columbia Rivers
Fraser River sockeye runs increased (from 3.3 million in1949 to 22 million in 1990)
Columbia River chinook crashed from historical runs of 8to 10 million to 450,000 in 1993 Hatchery production on the Columbia was ineffective in
making up for changing ocean conditions (beginning in1976); hatchery fish are more vulnerable to unproductive
ocean conditions Performance of salmon in the ocean is not independent
of human manipulation of the fresh water phase of theirlives(Lichatowich, 1999)

Changing Ocean Conditions
Changes in ocean currents can reduce abundance of phytoplanktonthat support fish species that salmon prey on
E.g., if springtime ocean currents change, the advantages of mixingof cold deeper waters with shallow warmer waters that provide coldwater nutrients to phytoplankton will be lost and salmon health will
deteriorate
Global warming/El Nio events can shift fish runs to the north, asmay have happened with the unusually high numbers of sockeye in2010 returning to the Fraser River (Canadian northern route) and
bypassing US southern route

The Missing Sockeye of 1994
14 million sockeye returned to the Fraser River in 1988 and 22million in in 1990, but the 1994 run was nearly obliterated: 2 million
sockeye (of 3.3 million estimated salmon) were lost and fisheries
were closed down. Fishing quotas had been set at 80% and nearly
caused zero reproduction
Tribal poachers and logging were blamed. A complete ban ontribal fishing was proposed (although tribes accounted for < 5% of
salmon taken annually). Sockeye runs in the late 90s and 2000s
were well below the 1980s until 2010.
Lesson: While Canadian fisheries practices were better managedmore holistic with an ecosystem management approach and with
science guiding the processchanges in ocean conditions were not
well understood and still are not

Historical Eco-cultural Richness of the PNW
Recent research suggests that the social andcultural richness of Pacific Northwest tribes wasthe result in part of sophisticated political and
legal systems linked to sophisticated resourcemanagement and harvest technologies
A stable food supply was ensured by thedeliberate spread of salmon and enhancedcomplexity of habitats by First Nations peoples-increasing salmon abundance, diversity, anddistribution(Nigel Haggan, UBC fisheries Centre, 2004)

Native People Cared for Salmonid Freshwater Habitat
Given the uncertainty of oceanic conditions, Nativepeople had to work hard at maintaining quality salmonstream habitat
Spawning beds were cleaned and log jams removed followinglarge storms
Sandspits blocking late summer/fall chinook runs were opened Trees were felled to divert stream water into side channels
creating backeddies for overwintering coho or to flush sedimentfrom spawning beds
Salmon spawn were transplanted in damp moss to streams withno or few salmon
Salmon were flumed or carried around landslides or iceblockages (this happened most recently in 1914 following thehuge slide on the Fraser River at Hells Gate canyonsavingsockeye runs)

Other conservation measures included:
Complex stone fishtraps for a wide range of marinespecies (including herring, eulachon, and perch)which were species and size specific (Herring wasand still is farmed on submerged hemlock boughs)(Nigel Haggan, 2004)
Use of weirs at river mouths to count and thencontrol harvestable fish before allowing them upriverto their natal spawning streams and other tribes
Regulation of fishing times, places, and gear basedon a sophisticated understanding of salmonreproductive biology and genetics

Local Control Over Local Resources
These and other conservation measures were sustainablymaintained by a land tenure system which divided fisheries andother marine resources (e.g. farmed clam beds) into units of localresponsibility and harvesting rights by individuals, families, andclans nested within a larger, collective tribal authority structurethrough which experienced knowledge specialists had the lastword on harvest regulation and rights during times of regional orseasonal shortages of particular runs
Fishing at the mouths of rivers and streams allowed accurate fishcounts, with quotas for use based on the relative abundance of
different fish runs
Trading between families of different salmon species ensured adiverse food supply and good nutrition (Nigel Haggan, 2004)

Adaptation to Climate Change
Adaptation to climate change will depend in large part in
the futureas it did for millennia with aboriginal fisheries
on a wide range of practical aquatic and terrestrialrestoration and conservation measures which in sum
enhance the genetic diversity of salmon by maintaining
high enough population numbers of all 5 salmonid
species to ensure genetic adaptability to warming
oceans and rivers.
[Those practical activities will be discussed in detail in the 2nd half of this
presentation]

Adapting the Indigenous ecosystem-based model to modern
conditions in complementarity with Western science
Adopt a holistic fisheries ecosystem managementstrategyinstead of single species population modeling
addressing restoration in both upland terrestrial(watershed) and riverine and estuarine-marine habitat
Work toward a site-specific local (community-based)regulatory structurelocal responsibility for localresourcesnested within larger tribal, regional, and state
\national structures, e.g. New England / Newfoundland

Use fishing gear which is species and size specific Favor natural regeneration of wild salmon stocks over hatchery fish where possible Find a balanced number of transferable license quotas and buy-backs of licenses by
governments (e.g. Canada) to encourage local access and control of local resources and
achieve distributive social justice while reducing fishing pressure on salmon. No open
access, but some constraints on transferable quotas needed to reduce social disruption.
(Coward et al, 2000; Berrill, 1997)
Utilize both Western science and traditional ecological knowledge (TEK). Local knowledgeprovides important information on stock structure, spawning grounds, juvenile habitat,
and seasonal and directional fish movements.
Scrap maximum sustainable yield model in favor of whole ecosystem\multispeciesmanagement (Iceland and Norway are already doing so)feasible in relatively simplecold ocean systems
No to No Net Loss salmon recoveryuse historically reconstructed baseline modelsinstead of just going with current population numbers as a baseline, e.g. target salmon
numbers lost to habitat destruction and dams instead of comparing cost of hatcheries vs.
income from fishing as a metric of sustainability

Ecosystem Management at the Watershed
Level and Climate Change Adaptation
Broad Goals
1. Maintain or restore key aquatic and riparian habitatstructure, composition, and processes (e.g. hydrologicfunction) affecting all organismsnot just fish (e.g.
invertebrate species richness: 196 terrestrial vertebratespecies, besides fish, utilize streamside macro-invertebrates)
2. Maintain or restore key upland forest structure,composition, and function with a broad range of light-shade conditions where possible by approachinghistorical tree stocking rates, landscape configuration,and composition to the extent possible given changedlandscape scale environmental conditions

Ecocultural Restoration
The process of recovering as much as is recoverable of the key
historic precontact ecosystem structure, composition, processes,
and function, along with traditional, time-tested, ecologically
appropriate and sustainable Indigenous cultural practices that
helped shape ecosystems, while simultaneously building-in
resilience to future rapid climate disruptions and other
environmental changes in order to maintain ecological integrity in
a way that ensures the survival of both Indigenous ecosystems
and cultures

Mimicking Native American Fire Regimes in their
Intensity, Frequency, Seasonality, Selectivity, and
Landscape Scale Pattern
The 100s of plant species utilized by First Nations
required a watershed level fire regime based on
periodic, low-intensity burns done rotationally at afrequency of from one to 10 or 15 years depending
on the resource targeted and its phenologyapplied
to a wide variety of plant communities rich in cultural
resources, including forest herbaceous understories,
montane meadows, prairie-savanna, wetlands,shrub-steppe, and riparian zones

Erosion Mitigation Measures
Minimize erosion by substituting mechanical thinning forfire in erodible soils (e.g. granitic soils) near streams
Dont thin or burn on steep (over 60%) slopes nearstreamsbalance those kinds of closed areas withadjoining opens and gaps on less steep and erodibleslopes for overall watershed structural heterogeneity
Phase out roads and recontour slopes\restore naturaldrainage patterns by using outsloped roads instead of
inboard ditches and culverts to restore historic hydrology
8/3/2019 Fraser Columbia 09-22-2011
34/52
Aim High
Avoid shifting baselines by referring climate
adaptation and mitigation goals to historical
conditions (Hardison and Williams, Tulalip Tribe, 2005; Haggan, 2004)
as an initial guide for restorationthat will be
modified by todays changed conditions but will alsoset a restoration trajectory that recovers the
historical range of variability of forest landscape
heterogeneity for sufficient microsite variability to
ensure genetic variability (a diverse gene pool) for
adaptation of populations and subspecies to rapidclimate destabilization and change
For Tribes: Assisted regeneration instead of assisted
migration

Global Warming Induced Changed Weather and Oceanic
Conditions in the Pacific Northwest
Current Ecohydrologic Conditions
Winter season reduced by roughly 2 months Longer warm fall rains and shorter spring snowmelt More precipitation falls as rain than snow, reducing snowpack Snow melts more rapidly and earlier in spring, resulting in higher peak
flows
Increased flows increase erosion and floods that deliver higher sedimentloads, nutrient loads, and contaminants in downstream receiving waters,
causing scouring and sedimentation; reduces infiltration and capacity of
wetlands and riparian vegetation to filter nutrients and toxins in runoff(Hardison and Williams, 2004)
Earlier snow melts are causing water to be available up to ~ 2 months before thenormal times of salmon arrival
Ocean acidification is reducing available calcium for shellfish and juvenile bonedevelopment of some fish species

Temperature Alterations
Loss of forest cover from clearcut logging has resulted inless stream shading and faster spring runoff; removal of
large logs has resulted in poor stream structurewithfew or no deep pools for summer cooling
Warm water induces whirly disease in salmon andincreases their susceptibility to other aquatic diseases(Hardison and Williams, 2004)
Loss of groupings of tall old-growth trees has reducedhumidity in forests with increased drying of forestunderstories, overstocked smaller trees and ladder fuels
resulting in increased fire hazard
8/3/2019 Fraser Columbia 09-22-2011
37/52
Species Range Shifts
As oceans warm, salmon have no place to go but north,e.g. sockeye salmon may move to the Bering Sea.(Haggan, 2004)
The extremely rapid rate of climate change could trapterrestrial species which may have a wide ecologicalamplitude but have genetically fixed times forreproduction and feeding resulting in population declinesand loss of tribal resources. (Hardison and Williams, 2004)
Evolutionary opportunities will increase for invasivegeneralist species and decrease for more conservativespecies

Balancing Carbon Sequestration with Restoration of
Biodiversity and Fire Hazard Reduction
Use variable density thinning model (Lindenmayer and Franklin, 2002)to create structural and compositional heterogeneity
Thin to release permanent old-growth softwoods and hardwoodsforreducing fire hazard and for future understory moisture retention andcarbon sequestration both in trees and in soil organic matter/legacy
charcoal, enhanced by forest openings which support rich perennial
herbaceous and fern understories
Structure longterm timber harvest rotations (120 years or longer) andfuture permanent old-growth trees in groupings which provide a widerange of light-shade conditions appropriate to the forest typefor
biodiversity, species composition, and gene pool restoration (facilitated
by enough spacing between tree groupings to allow good gene flow)

Restoring Forest Hydrologic Function to Benefit
Salmonid Aquatic Habitat
Remove sufficient number of smaller treesespecially invasive shadetolerant conifers in interior coastal mountainsto reduce
evapotranspiration and increase groundwater quantity
Restore beavers for groundwater recharge and increased fish diversity,abundance, health and juvenile survival
Increase soil infiltration capacity by creating openings and gapsandmaintaining montane meadowswhich support long-lived herbaceous
perennials such as native bunchgrasses with extensive root systems
which can loosen compacted soils in the appropriate plant
communities. Native grasslands are a good underground carbon sink.
Greater water quantity translates into greater water quality forsalmonids
