Title: HOW DO WE CONSERVE BIOLOGICAL DIVERSITY?


1
HOW DO WE CONSERVE BIOLOGICAL DIVERSITY?
  • 5 Strategies to Keeping Species Alive

2
1. Protected Areas
  • Governments set aside land to protect species
  • Provincial and National Parks
  • Allow animals to live in relatively undisturbed
    environments
  • 244 540 square kilometers of Canada is national
    park land

3
Canadian National Parks Map

List of National Parks in Western Canada
  • Banff
  • Jasper
  • Waterton Lakes
  • Elk Island
  • Wood Buffalo
  • Glacier
  • Gulf Islands
  • Kootenay
  • Mount Revelstoke
  • Yoho
  • Gwaii Haanas
  • Pacific Rim
  • Riding Mountain
  • Wapusk
  • Grasslands
  • Prince Albert
  • Ivvavik
  • Kluane
  • Vuntut
  • Nahanni

5
In-Situ Conservation
  • Provincial and National Parks are examples of
    in-situ conservation
  • These areas keep species in their natural
    environments rather than removing them

6
Establishing Wildlife Corridors
  • Corridors are important to share genetic
    information between populations
  • All levels of government must work together to
    make these work

7
2. Restoration of Ecosystems and Species
  • There are various programs to restore endangered
    species and their habitats
  • Could be charities, non-profit organizations,
    volunteer groups or private citizens doing the
    restorations
  • Some examples include

8
Ducks Unlimited Canada
  • Conserves wetlands and other habitats for
    Canadas waterfowl - ducks, geese, loons, etc.
  • Private non-profit organization
  • www.ducks.ca

9
Nature Conservancy of Canada
  • Purchases land and turns it into an area to
    protect habitat and endangered species
  • Owns about 1.8 million acres of Canada
  • www.natureconservancy.ca

10
Friends of Fish Creek
  • protect, preserve, and enhance the diverse
    natural and human history found in Fish Creek
    Provincial Park.
  • Non-profit and volunteer-driven
  • www.friendsoffishcreek.org

11
World Wildlife Fund
  • stop the degradation of the planet's natural
    environment and to build a future in which humans
    live in harmony with nature
  • Protects 96 millions acres in Canada through
    endangered species programs
  • www.wwf.ca

12
3. Resource Use Policies
  • Governments pass laws to protect species that are
    endangered or threatened
  • These laws say that these species cannot be
    hunted or captured

13
Species at Risk Act
  • Passed by the Canadian government in June 2004
  • framework for actions across Canada to ensure
    the survival of wildlife species and the
    protection of our natural heritage
  • To see a copy of this legislation, go to
    http//www.sararegistry.gc.ca/the_act/HTML/Guide_e
    .cfm

14
Committee on the Status of Endangered Wildlife in
Canada (COSEWIC)
  • This is the national committee that studies
    organisms across Canada
  • Determines whether or not organisms need to be
    protected by law
  • Currently there are 456 Species at Risk in Canada
    (including 67 mammals and 60 birds)
  • If people harm animals protected by this law,
    they face up to a 250 000 fine and/or up to five
    years in prison

15
4. Controlling the Spread of Exotic Species
  • A new species in an environment can have
    disastrous consequences
  • There are two examples of this

16
Purple Loosestrife
  • Introduced to Alberta from Europe in the 1800s
  • A plant that lives near wetlands
  • Nothing eats this plant or uses it for shelter
  • Purple loosestrife will reduce the size of
    natural plant communities
  • Important to control this plant so that wetlands
    can continue to flourish

17
Rabbits in Australia
  • Englishman Thomas Austin brought 24 rabbits into
    Australia in 1859 because he was homesick
  • These 24 rabbits reproduced and soon after the
    species was found all across the continent
  • Rabbits would eat the grass and kill trees by
    stripping their bark
  • Ate grass that should have been for sheep this
    cut down on Australias wool exports

18
Controlling Rabbits in Australia
  • Government gave rewards to people who killed
    rabbits
  • Built a 2000 mile fence to protect key cereal
    crops
  • In 1950, the government introduced a virus that
    killed rabbits
  • As of 1997, there were still 300 million rabbits

5. Conservation of Genetic Resources
  • These involve any activity that helps to store
    the genetic variations of as many of the worlds
    species as possible
  • Ex-Situ Conservation the maintenance of
    organisms outside of their ecosystems
  • Two examples are SEED BANKS and ZOOS

21
Seed Banks
  • Established to gather and store seeds from plants
    that are threatened by extinction
  • Scientists are able to preserve the genetic
    diversity of many plant species
  • One of the largest is the Royal Botanic Gardens
    in London, England

22
Zoos
  • The Calgary Zoo performs many functions
  • Educational institution for children to visit
  • Supports biodiversity research going on around
    the world
  • Part of a worldwide network to protect and
    preserve endangered animals
  • Share animals with zoos around the world to
    maintain the genetic diversity

Do we need Zoos?
  • PROS
  • Provide a place for animals with damaged or
    limited habitat
  • Maintain biodiversity with animal breeding
    programs
  • Supports research to re-establish extirpated
    species
  • CONS
  • Animals are put in enclosures so humans can
    observe them, causing stress to the animals
  • Many animals wont breed in captivity so their
    genes are lost
  • Money spent on zoos would be better spent
    protecting natural habitats
