Although the wood frog is not endangered or threatened, in many parts of its range, urbanization is fragmenting populations. Several studies have shown, under certain thresholds of forest cover loss or over certain thresholds of road density, wood frogs and other common amphibians begin to "drop out" of formerly occupied habitats.
Found at latitudes up to 71° N, it is the northernmost wild amphibian species. [4] Favoring lowlands, it is seldom encountered at elevations of more than 600 m. [1] A habitat generalist, Rana amurensis favors open ground, but is also found in both deciduous and coniferous forests. In the winter, it hibernates on pond bottoms.

Some frogs such as the wood frog, moor frog, or spring peeper can even survive being frozen. Ice crystals form under the skin and in the body cavity but the essential organs are protected from freezing by a high concentration of glucose.
The wood frog (Rana sylvatica) [20] [21] [27] has a broad distribution over North America, extending from the southern Appalachians to the boreal forest with several notable disjunct populations including lowland eastern North Carolina. In Idaho, wood frogs are found only in Boundary and Bonner counties. [29]
