Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA HYLIDAE

Scientific Name: Hyla chrysoscelis
Species Authority: Cope, 1880
Common Name/s:
English Cope's Gray Treefrog
Taxonomic Notes: This species is not distinguished from the very similar Hyla versicolor in most published literature; it is distinguished by chromosomes, erythrocyte size (Matson 1990), and call characteristics.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor/s: Geoffrey Hammerson
Reviewer/s: Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description: This species' geographic range is not precisely determined, although it covers most of the southeastern and central USA and part of south-central Canada. It is sympatric with H. versicolor in south-central U.S. and Wisconsin area and perhaps many other areas as well. See Little et al. (1989) for information on distribution in West Virginia, southern Ohio, and southwestern Pennsylvania.

Population: Total adult population size is unknown but apparently common. It is probably relatively stable.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: Its geographic range includes wooded areas and woodland edges (including woodlots in prairies), usually within a few hundred meters of water. It is often found in recently disturbed areas with abundant shrubs, herbaceous growth, and vines. It is an arboreal and terrestrial species. When inactive, it may hide in tree holes, under bark, under leaves, or under tree roots. In Tennessee, frogs associated with knothole cavities in trees in fall were not there after mid-November (Ritke and Babb 1991). Eggs are laid and larvae develop in temporary or permanent waters of flooded ditches, puddles, river sloughs, creeks, and small ponds, where there are woody branches or extensive herbaceous growth along the edges. Males call from water surface or from vegetation or ground near water. Individuals generally breed in the same site in successive years (Ritke et al. 1991).
Systems: Terrestrial; Freshwater
