According to a recent findings, the golden langur, a rare primate species endemic to the Indo-Bhutan border region, is facing a severe threat of extinction due to rapid habitat loss and deforestation in Assam.
- Over half of India’s golden langur’s habitat has disappeared in recent decades. This loss is particularly pronounced in the southern part of its distribution range, specifically in the Kokrajhar and Bongaigaon districts of Assam.
- The main driver of this habitat loss is deforestation, exacerbated by the conversion of forests into farmland and human settlements.
- The fragmentation of once extensive forested areas into smaller, isolated patches, further jeopardizing the species’ survival.
- The increasing risks faced by these primates, includes road accidents, electric hazards, and higher exposure to parasites.
- Researchers have implemented innovative solutions such as artificial canopy bridges (ACBs) in high-risk areas.
- Researchers are focusing on connective bridges, constructed using materials like HDPE pipes and plastic ropes, aim to provide safe passage for the langurs across fragmented habitats.
About Golden langurs
- Golden langurs get their name from the striking golden-orange colour of their fur.
- The golden langur (Trachypithecus geei), an obligate canopy-dwelling primate, is primarily found in four districts of western Assam and six districts of south-central Bhutan.
- As arboreal primates, these langurs are particularly vulnerable to habitat fragmentation and linear infrastructure development.
- The entire distribution range of the golden langur (Trachypithecus geei) covers the Manas Biosphere Reserve and all fragmented forests in the western part of Assam.
- Golden Langurs belong to a large group of Old World monkeys called the colobines (subfamily Colobinae).
- The Colobines are principally leaf eating primates and have a ruminant like multichambered stomach.
- IUCN Status: Critically Endangered; CITES: Appendix I; Wildlife (Protection) Act, 1972: Schedule I.
