The Namdapha Flying Squirrel, missing for four decades, has resurfaced in Arunachal Pradesh. Last documented in 1981, this nocturnal flying squirrel is indigenous to the Changlang district and endemic to Arunachal Pradesh, specifically the Namdapha National Park.
Initially discovered in the Mesua Ferrea jungles bordering the Noa Dihing river in Arunachal Pradesh, an area now covered by Namdapha National Park, the Namdapha Flying Squirrel is often confused with the Red Giant Flying Squirrel, another species found in the region. Distinguishing between the two presents a considerable challenge due to their similar appearances.
The Namdapha Flying Squirrel has reddish grizzled fur with white markings. Its crown displays a pale grey hue, while its patagium (a membrane or fold of skin between the forelimbs and hindlimbs) exhibits an orangish color, and its underparts are white.
The squirrel is among the ‘25 most wanted lost species’ identified by the Global Wildlife Conservation’s Search for Lost Species initiative. Additionally, it is protected under Schedule II of the Wildlife Protection Act 1972 and is classified as critically endangered on the IUCN Red List. Out of the 43 recognized flying squirrel species worldwide, the Namdapha Flying Squirrel is one. It faces multiple threats, including habitat loss, destruction, landslides, flooding, and poaching, among others.
The recent discovery was made by the Aaranyak wildlife organization’s team, which observed the species for over an hour. The confirmation was based on distinctive features such as prominent ear tufts and behavior distinguishing it from the Red Giant Flying Squirrel.
