Habitat and conservation
Scutiger boulengeri is an alpine species that lives near streams and lakes in grassland habitats at elevations of 3,300–5,270 m (10,830–17,290 ft) above sea level.[1] A healthy population has been found at an elevation of 5,270 m (17,290 ft) in the Gurudongmar Lake complex in Sikkimese Himalaya.[3] This is one of the highest elevations where amphibians have ever been recorded. They hibernate in loose soil from September to March or April.[3]
Scutiger boulengeri is not considered threatened and is ranked as a species of least concern by the IUCN Red List.[1]
