Recently, a family of Hoolock gibbons was rescued in the Lower Dibang Valley district of Arunachal Pradesh by local officials. This event highlights the ongoing efforts to protect these unique primates.
Hoolock gibbons are recognized as the smallest and fastest of all apes, thriving in tropical and subtropical forests throughout Southeast Asia. Among the 20 gibbon species worldwide, the hoolock gibbon stands out as the only member of the ape family found in India.
The distribution of hoolock gibbons covers regions in Southeast Asia, including India, Myanmar, Bangladesh, and southern China. In India, they inhabit states such as Assam, Meghalaya, Arunachal Pradesh, Nagaland, Manipur, Mizoram, and Tripura, primarily south of the Brahmaputra River. The Hollongapar Gibbon Sanctuary in Assam is noted for having the largest population of hoolock gibbons.
These gibbons are divided into two categories: the Eastern Hoolock Gibbon (Hoolock leuconedys), primarily found in a designated region of Arunachal Pradesh, and the Western Hoolock Gibbon (Hoolock hoolock), which is more widely distributed across the northeastern states.
Hoolock gibbons are diurnal and arboreal creatures, adept at moving through the trees using their long arms. They are known for their monogamous nature, often forming lifelong partnerships with a single mate. Living in small family units, these gibbons communicate with each other through distinctive vocalizations.
The average lifespan of a hoolock gibbon is around 25 years, which indicates their need for long-term conservation efforts.
According to the IUCN Red List, the Eastern Hoolock Gibbon is classified as Vulnerable, while the Western Hoolock Gibbon is considered Endangered. Both species are protected under Schedule I of the Wildlife (Protection) Act of India, 1972, highlighting the necessity for ongoing conservation initiatives to safeguard their future.
