Known as CARCNET, the Canadian Amphibian and Reptile Conservation Network is an organization devoted to conserving Canada's native species of amphibians and reptiles. The bilingual (French & English) website provides lots of information to include a valuable ID guide with field photography and nomenclature of 2 Tailed Frogs; 2 Spadefoot Toads; 5 True Toads; 7 Tree Frogs; and 9 True Frogs. An Identification Key is easy to follow and a good learning aid to differentiate among the 5 families previously mentioned. Finally the site provides full article access to their scientific publication "The Canadian Herpetologist." Hope this links helps forum members learn more about Canadian frogs and their biology, thank you !
