1. ENDANGERED SPECIES Chapter 1.2

2. SPECIES AT RISK Species whose populations decline below a certain level are considered to be at risk. In Canada, more than 250 species of plants and animals are at various degrees of risk.

3. Why are Species at Risk? The reasons for an ecosystem decline, are the same reasons why certain species are put at risk. 1. Loss of Habitat 2. Pollution 3. Diseases 4. Climate Change 5. Over Harvesting

4. HIGH PROFILE AT-RISK SPECIES BALD EAGLE PANDA BEAR BUFFALO’S See Page 15 of text to look at Canada’s “at- risk” species. The word “at-risk” is used because it encompases all five levels.

5. Classification system for At-Risk Species  1. EXTINCT – A species that is not found anywhere  EXAMPLES:  Blue Walleye (Type of Fish-1965 )  Passenger Pigeon ( 1914 )

10. 3. EXTIRPATED  Any species that no longer exists in one part of Canada, but can be found in others  EXAMPLES:  Grizzly Bear ( no longer in Man. and Sask but found in Alberta and BC.)

11. Grizzly Bear

12. 4. THREATENED  Any species that is likely to become endangered if factors that make it vulnerable are not reversed.  EXAMPLES:  Wood Bison ( small number)  Anatum Peregrine Falcon ( captive breeding is helping to restore population.)

14. 5. VULNERABLE or Special Concern  Any species that is at risk because of low or declining numbers at the fringe of its range or in some restricted area.  EXAMPLES:  Grey Fox  Atlantic Cod  Blue Heron  White tail Deer
