British Columbia has 22 species of amphibians -- 20 of which are native to the
province. Both the Bullfrog and the Northern Green Frog have been introduced to
southwestern BC. There is a greater diversity of species in the southern half of the
province, although 6 species are found as far north as the border with the Yukon and
Northwest Territories. The Rocky Mountains naturally divide BC from the rest of Canada
and because of this 13 species are found nowhere else in Canada.
