|Scientific Name:||Hyla versicolor|
|Species Authority:||LeConte, 1825|
|Taxonomic Notes:||This species is not distinguished from the very similar Hyla chrysoscelis in most published literature; it is distinguished by chromosomes, erythrocyte size (Matson 1990), and call characteristics.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Hammerson, G.A. & Pelletier, S.|
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification and presumed large population.
|Range Description:||This species' geographic range is not precisely determined, although it covers much of the eastern USA and southeastern Canada. It is sympatric with Hyla chrysoscelis in Wisconsin, south-central U.S., and probably many other areas. See Little et al. (1989) for distribution in West Virginia, southern Ohio, and southwestern Pennsylvania. See McAlpine et al. (1991) for information on distribution in eastern Maine and southwestern New Brunswick.|
Native:Canada (Manitoba, New Brunswick, Ontario, Québec); United States (Arkansas, Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Virginia, West Virginia, Wisconsin)

|Population:||The total adult population size is unknown but it is abundant and probably stable.|
|Habitat and Ecology:||It inhabits various kinds of wooded and forested habitats. It is both arboreal and terrestrial. It hides in tree holes, under bark, in rotten logs, under leaves and under tree roots when inactive. Eggs and larvae develop in shallow woodland ponds and marshes, puddles, ponds in forest clearings, swamps, bogs and many other kinds of permanent or temporary waters lacking a significant current, including ponds created through excavation by humans. In northern Minnesota, successful reproduction in acidic bog water either does not occur or is a rare event (Karns 1992). In central Ontario, embryos and larvae exhibited high degree of acid tolerance (J. Herpetol. 26:1-6).|
|Use and Trade:||
It is found in the pet trade.
|Major Threat(s):||Introduced bluegill sunfish might cause declines in larval tree frog abundance (Smith et al. 1999).|
|Conservation Actions:||Its range overlaps with many protected areas. No conservation measures are needed.|
