List of amphibians of Michigan

[1][2] Blanchard's cricket frog, a subspecies of northern cricket frog, is considered to be threatened and two species, the marbled salamander and small-mouth salamander, are considered endangered; these are protected under the Endangered Species Act of the State of Michigan.

Two more species, the boreal chorus frog and lesser siren, are considered to be of special concern, although they are not protected under the act.

However, Michigan's species live where it is often cold, necessitating adaptions to freezing weather due to their ectothermic (cold-blooded) nature.

[2] Amphibians are vulnerable to many types of human encroachment, including water pollution, automobiles, the destruction of wetlands through farming and the use of off-road vehicles and chemical pesticides.

There are extensive wetlands, dominated by coniferous forests, while upland areas provide mixed conifer/broadleaf hardwood tracts.
