Significant decline in the habitat of the Golden Langur

A recent study by scientists has suggested a significant decline in the habitat of the golden langur (Trachypithecus geei), an endangered primate species distributed in the transboundary region of Bhutan and India.

Key-Points

A recent paper titled “Future simulated landscape predicts habitat loss for the golden langur: a range-level analysis for an endangered primate” throws light on whether the habitat of the endangered primate is protected or not. The paper has been published by scientists of the Zoological Survey of India (ZSI).

Golden langurs are easily recognised by the colour of their fur, and are distributed in the forested habitats of Tsirang, Sarpang, Zhemgang and Trongsa districts of Bhutan.

In India, fragmented and isolated populations of the species are distributed in Chirang, Kokrajhar, Dhubri and Bongaigaon districts of Assam.

The results indicate that out of the total range extent (66,320 square km), only 12,265 square km (18.49%) is suitable for the species at present, which will further be reduced to 8,884 square km by the year 2031, indicating major range contraction.

Conservation Status: In 2003, they were considered endangered by the IUCN Red List, and listed as Appendix I on the CITES website.

Chakrashila is India’s first wildlife sanctuary with golden langur as the primary species. Chakrashila has about 600 golden langurs whose population is scattered across western Assam and the foothills of Bhutan.
