Why is the bamboo pit viper silently disappearing from Gujarat’s forests?
In the humid forests of the Dangs district, Gujarat, a discreet and little-known species struggles to survive. The bamboo pit viper, recognizable by its intense green color and triangular head, is the only venomous snake in this region. Yet, despite its presence in thirteen Indian states, its habits and conservation status remain poorly understood.
Research conducted between 2022 and 2025 reveals that these snakes spend their nights perched between three and seven meters high, on exposed roots, shrubs, or bamboo. They hunt by ambush, remaining motionless near underground shelters where they hide during the day. Their activity peaks between February and June, before the monsoon rains make them almost invisible. During this season, they leave their perches for drier shelters, thus avoiding landslides and floods.
A surprising behavior has been observed: these vipers systematically return to the same spot after being relocated, sometimes in less than three days. Some even remain in pairs for weeks, suggesting a form of seasonal monogamy during the breeding period. Their loyalty to a specific site makes them particularly vulnerable to human disturbances.
The threats they face are numerous. Forest fragmentation, caused by deforestation and soil erosion, destroys their habitats. Illegal wildlife trafficking also worsens their decline. In 2023, poachers equipped with bags and hooks were caught hunting these snakes, confirming the urgency of protecting the region.
In response to these dangers, conservation measures are beginning to emerge. Local authorities are considering creating protected areas where the cutting of bamboo and trees would be prohibited. These spaces would help limit erosion and preserve the vipers’ natural refuges. Better education of local populations could also reduce conflicts between humans and snakes, which are often killed out of fear or ignorance.
The bamboo pit viper, with its sedentary habits and role as an ecological indicator, could become a model for studying the impact of climate change on wildlife. Its silent decline reminds us that even species classified as of least concern can rapidly shift to a critical status if no action is taken. Protecting its forests is not just a matter of survival for this snake, but also for the balance of an entire ecosystem.
