In-Situ Conservation
Provincial and National Parks are Provincial and National Parks are examples of in-situ conservationexamples of in-situ conservation
These areas keep species in their These areas keep species in their natural environments rather than natural environments rather than removing themremoving them
Establishing Wildlife Corridors
Corridors are Corridors are important to share important to share genetic information genetic information between populationsbetween populations
All levels of All levels of government must government must work together to work together to make these workmake these work
#2. Restoration of Ecosystems and Species There are various programs to restore There are various programs to restore
endangered species and their habitatsendangered species and their habitats Could be charities, non-profit Could be charities, non-profit
organizations, volunteer groups or organizations, volunteer groups or private citizens doing the restorationsprivate citizens doing the restorations

#3. Resource Use Policies
Governments pass laws to protect Governments pass laws to protect species that are endangered or species that are endangered or threatenedthreatened
These laws say that these species These laws say that these species cannot be hunted or capturedcannot be hunted or captured
Species at Risk Act
Passed by the Canadian government in June Passed by the Canadian government in June 20042004

#4. Controlling the Spread of Exotic Species A new species in an environment can A new species in an environment can
have disastrous consequenceshave disastrous consequences There are two examples of this…There are two examples of this…

Important to control this plant Important to control this plant so that wetlands can so that wetlands can continue to flourishcontinue to flourish
Rabbits in Australia
Englishman Thomas Austin brought 24 Englishman Thomas Austin brought 24 rabbits into Australia in 1859 because he was rabbits into Australia in 1859 because he was homesickhomesick
These 24 rabbits reproduced and soon after These 24 rabbits reproduced and soon after the species was found all across the the species was found all across the continentcontinent
Rabbits would eat the grass and kill trees by Rabbits would eat the grass and kill trees by stripping their barkstripping their bark

#5. Conservation of Genetic Resources These involve any activity that helps to These involve any activity that helps to
store the genetic variations of as many store the genetic variations of as many of the world’s species as possibleof the world’s species as possible
Ex-Situ Conservation – Ex-Situ Conservation – the the maintenance of organisms outside of maintenance of organisms outside of their ecosystemstheir ecosystems
Two examples are: SEED BANKS and Two examples are: SEED BANKS and ZOOSZOOS
Seed Banks
Established to gather and store seeds Established to gather and store seeds from plants that are threatened by from plants that are threatened by extinctionextinction
Scientists are able to preserve the Scientists are able to preserve the genetic diversity of many plant speciesgenetic diversity of many plant species
One of the largest is the Royal Botanic One of the largest is the Royal Botanic Gardens in London, EnglandGardens in London, England
Zoos
The Calgary Zoo performs many The Calgary Zoo performs many functionsfunctions– Educational institution for children to visitEducational institution for children to visit– Supports biodiversity research going on Supports biodiversity research going on

Do we need Zoos?
PROSPROS– Provide a place for Provide a place for

CONSCONS– Animals are put in Animals are put in
enclosures so humans enclosures so humans can observe them, can observe them, causing stress to the causing stress to the animalsanimals
– Many animals won’t Many animals won’t breed in captivity so their breed in captivity so their genes are lostgenes are lost
