Fifteen-year survey identifies three new cascade frog species

Researchers working across Northeast India's forest streams over 15 years have identified three new cascade frog species from Tripura, Nagaland and West Bengal. One was named in memory of a Kerala social worker known as Ammachi. The discoveries expand the documented amphibian diversity of a region where stream habitats face continuing ecological pressure.

Why it matters

Newly described species can change conservation priorities because narrow ranges make stream-dependent amphibians vulnerable to habitat disruption before their populations and ecological roles are fully understood.

Evidence assessment

EastMojo summarises the long field search and three locations; the supplied material does not include the taxonomic paper or population estimates.

Medium confidence — The regional report provides specific research history and geography, with scientific documentation not separately available here.
