Global Range: (5000-200,000 square km (about 2000-80,000 square miles)) 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.

Justification
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.

Global Short Term Trend: Relatively stable (=10% change)

Comments: 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.

Global Long Term Trend: Increase of 10-25% to decline of 30%

Wikipedia

Pseudacris kalmi

The New Jersey chorus frog (Pseudacris kalmia) is a species of frog found in the states near New Jersey in the United States. It was formerly considered as subspecies of Pseudacris triseriata.[1]

Names and Taxonomy

Taxonomy

Comments: A molecular phylogeny of Pseudacris based on mtDNA data (Moriarty and Cannatella 2004) revealed four strongly supported clades within Pseudacris: (1) A West Coast Clade containing regilla and cadaverina, (2) a Fat Frog Clade including ornata, streckeri, and illinoensis, (3) a Crucifer Clade consisting of crucifer and ocularis, and (4) a Trilling Frog Clade containing all other Pseudacris. Within the Trilling Frog Clade, brimleyi and brachyphona form the sister group to the Nigrita Clade: nigrita, feriarum, triseriata, kalmi, clarkii, and maculata. The Nigrita Clade shows geographic division into three clades: (1) populations of maculata and triseriata west of the Mississippi River and Canadian populations, (2) southeastern United States populations of feriarum and nigrita, and (3) northeastern United States populations of feriarum, kalmi, and triseriata. Moriarty and Cannatella (2004) found that subspecific epithets for crucifer (crucifer and bartramiana) and nigrita (nigrita and verrucosa) are uninformative, and they therefore discouraged recognition of these subspecies. They concluded that further study is needed to determine if illinoensis warrants status as a distinct species. Molecular data were consistent with retention of regilla, cadaverina, ocularis, and crucifer in the genus Pseudacris.

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; found strong evidence for recognizing P. kalmi as a distinct species; and discovered a previously undetected species in the south-central United States (now known as P. fouquettei; Lemmon et al. 2008). Based on mtDNA data, Pseudacris maculata and P. clarkii did not emerge as distinct, monophyletic lineages but, given the degree of morphological and behavioral divergence between the taxa, Lemmon et al. (2007) chose to recognize them as separate species, until further data suggest otherwise.
