Habitat & Geographic Range
Calamus
Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical coniferous forests within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Widely distributed across Africa (South Africa), Asia (5 countries), Europe (30 countries), and North America (Canada, United States).
Chuanbei Toothed Toad
Typically found in freshwater habitats, moist forests, and wetlands.
Calamus
The Calamus (Acorus calamus) is a species in the genus Acorus. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical coniferous forests within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Chuanbei Toothed Toad
The Chuanbei Toothed Toad (Oreolalax chuanbeiensis) is an Endangered amphibian endemic to the mountains of northern Sichuan Province in southwestern China. It belongs to the family Megophryidae, a diverse group of litter frogs and toad-like amphibians that is particularly species-rich in the eastern Himalayan and southwestern Chinese highlands. The species name chuanbeiensis refers to northern Sichuan (Chuanbei), reflecting its highly restricted geographic range. Like other Oreolalax species, the Chuanbei Toothed Toad is associated with cold, fast-flowing mountain streams, where larvae develop in torrent conditions that require specialized morphological adaptations including oral suckers. Adults are terrestrial outside the breeding season, sheltering in leaf litter and rocky crevices in montane forest. The IUCN has assessed this species as Endangered due to its small known range, ongoing habitat degradation from logging, agriculture, and infrastructure development in mountain areas, and the impacts of chytridiomycosis (amphibian chytrid fungal disease) which threatens Asian megophryid frogs. Limited survey data mean that the species' full extent of occurrence and population size are poorly constrained.
