Oligodon juglandifer has been assessed as Vulnerable due to its estimated extent of occurrence of approximately 14,600 km², its presence in less than ten locations in the Eastern Himalayas, and the continuing decline in the extent and quality of its habitat. Monitoring of the population and distribution of this species is recommended to determine any further declines which could lead to the species being uplisted to a higher threat category in the future.

Threats [top]

Major Threat(s): Habitat degradation and loss may pose a major threat to this species. Total forest cover in the Eastern Himalayas of India has been projected to decrease from 90.5% in 2000 to 70.4% in 2100 with the highest regional losses in Sikkim (Pandit et al. 2007). Causes of deforestation in the Indian Eastern Himalayas include agricultural expansion, primarily for monocrop plantations as well as timber, fuel-wood and other forest product extraction (Bhuyan et al. 2003).

Conservation Actions [top]

Conservation Actions: This species was considered in the Conservation Assessment and Management Plan (CAMP) Workshop for the Amphibians and Reptiles of India, which was convened by the Biodiversity Conservation Prioritization Project, India, and held in Coimbatore in 1997. Further research and monitoring of the population numbers and distribution of this species is needed.
