Taxonomic CommentsNuclear phylogenetic analysis by Ospina et al. (2020) supported a clear split between Northern and Southern clades of Pseudacris brachyphona. In light of genetic, acoustic, and ecological divergence between the clades, they elevated the taxonomic status of the Southern clade and named this species P. collinsorum.

Rank ReasonsThis species has a limited range in the southeastern U.S. It is protected on several conservation lands throughout the range. Threat impacts, which include habitat loss, habitat degradation, and road mortality, are considered low at this time.
Range Extent CommentsThis species inhabits the southernmost portion of the Appalachian Mountains on the Piedmont, Ridge and Valley, and Plateau regions, and adjacent northern Coastal Plain, USA. It does not occur farther north than the southern portion of the Blue Ridge Mountains and the Tennessee River (Ospina et al. 2020). The distribution includes the northern half of the state of Alabama, south to the Tennessee River, northeast corner of Mississippi, northwest Georgia, and southwestern corner of North Carolina (Ospina et al. 2020). Using Global Biodiversity Information Facility (GBIF 2024) records, range extent is estimated to be 81,669 km².
Occurrences CommentsThere are approximately 33 occurrences (GBIF 2024).
Threat Impact CommentsConversion of hardwood forests to loblolly pine (Pinus taeda) plantation has likely degraded habitat suitability in Mississippi (Tom Mann, pers. comm. 2024). Loss of suitable upland habitat extending farther than 150 m from the shoreline of a breeding wetland likely has negative impacts on the population (McCoy et al. 2021). Other members of the genus Pseudacris in the southeastern U.S. are susceptible to infection by the chytrid fungus (Batrachochytrium dendrobatidis) (Rothermel et al. 2008), but it is not yet known if this species is susceptible. Road mortality is a possible threat that needs further study. It is unknown how this species will respond to climate change.
Ecology & Habitat
Habitat
Southern Piedmont dry pine forest, East Gulf dry upland hardwood forest, and southern Ridge and Valley/Cumberland dry calcareous forest (Ospina et al. 2020). These habitats contain dry to dry-mesic forests primarily dominated by pine and oak species. This species is associated with areas where precipitation during the driest season is relatively high (~260–500 mm), which probably allows for their survival in predominantly drier habitats (Ospina et al. 2020). It has also been observed breeding in regularly mowed orchard environments where breeding ponds are available and forest habitat is nearby (McCoy et al. 2021).
Ecology
It is possible forest habitat is preferred due to its more stable soil moisture despite being drier, on average, than nearby grassland soils which have more widely varying moisture levels (McCoy et al. 2021).
Reproduction
Females typically attach egg masses to vegetation (McCoy et al. 2021). Females average 16.5 egg masses per breeding season, each containing an average of 20 eggs for an average annual egg production of 338 eggs per female per year (McCoy et al. 2021).
