Chirixalus nongkhorensis, also known as the Nongkhor Asian treefrog, Nongkhor pigmy tree frog, Nong Khor bushfrog, and Nongkhor foam-nest treefrog, is a species of frog in the family Rhacophoridae. It is found in north-eastern India (Assam), Myanmar, Thailand, Cambodia, Laos, Vietnam, and Peninsular Malaysia.
Chirixalus nongkhorensis occurs in a wide range of both open and forested habitats, often affected by human disturbance, at elevations of 78–1,660 m (256–5,446 ft) above sea level. Breeding takes place around the rainy season adjacent to still bodies of water; the eggs are laid in foam nests attached to the underside of leaves overhanging water, to which the tadpoles drop upon hatching.
This species could be threatened by forests loss, although it appears quite adaptable. It is present in a number of protected areas. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Nongkhor Asian Treefrog is recorded against all the amphibians logged in Kaeng Krachan National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
