Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Hylidae

Scientific Name: Pseudacris kalmi Harper, 1955
Common Name(s):
English New Jersey Chorus Frog
Pseudacris triseriata Harper, 1955 ssp. kalmi
Taxonomic Notes: Using mtDNA samples from a large number of localities throughout North America, Lemmon et al. (2007) elucidated the phylogenetic relationships and established the geographic ranges of the trilling chorus frogs (Pseudacris). They redefined the ranges of several taxa, including P. maculata, P. triseriata, and P. feriarum, and found strong evidence for recognizing P. kalmi as a distinct species.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Geoffrey Hammerson
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Least Concern in view of the fairly 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:Range includes extreme southeastern Pennsylvania, New Jersey, and the Delmarva Peninsula of eastern Maryland, Delaware, and Virginia (Tobey 1985, Hulse et al. 2001, White and White 2002, Lemmon et al. 2007). Conant and Collins (1991) stated that the species ranges north to Staten Island, New York, but Gibbs et al. (2007) did not indicate any historical or extant occurrences of this frog in that area.

Population [top]

Population:This species is represented by a large number of occurrences. Total adult population size is unknown but presumably exceeds 10,000. This frog is common throughout the Coastal Plain of the Delmarva Peninsula (White and White 2002).

Trends are not well documented, but area of occupnacy, number of subpopulations, and population size probably are declining at a rate of less than 10 percent over 10 years or three generations.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This frog occupies various moist habitats, including grassy floodplains and wet woodlands containing shallow wetlands (ephemeral pools, ditches, wooded swamps, freshwater marshes) in which breeding occurs (White and White 2002). Eggs are attached to submerged vegetation.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): No major threats are known, but locally the species likely has been reduced or eliminated as a result of conversion of habitat to human uses.

Conservation Actions [top]

Conservation Actions: At least several occurrences are in protected areas.
