Amphibians and Reptiles

Canada is home to 45 species of amphibians and 46 species of reptiles. Populations of both amphibians and reptiles are declining in Canada. 36% of Canada's 45 amphibian species have declined to the point that they have been designated as endangered, threatened, or of special concern and 46% of Canada's 46 reptile species are at risk. These disappearing species are worrisome because they tell us how well our environmental is doing.

Disappearing habitat is one of the main problems. In southern Ontario, over 90% of wetlands have been lost. Even when good habitats remain, however, habitat fragmentation can also cause population isolation and declines.

Some amphibians can survive in agricultural areas but the use of pesticides, fertilizers, and other agricultural chemicals poses a documented threat. In Quebec, grossly deformed frogs have been found in areas where pesticide use is especially heavy.
