Context:

The rare long-snouted vine snake (Ahaetulla longirostris) was recently rediscovered in the Dudhwa Tiger Reserve, Uttar Pradesh. This sighting, the first of its kind in the state and only the second recorded instance in India, occurred unexpectedly during a rhino release operation in the Palia division.

Physical Characteristics and Habitat of long-snouted vine snake:

·        The long-snouted vine snake is characterized by its elongated, slender body, which can be green or brown.

·        Its most distinctive feature is the elongated snout (rostrum), an adaptation that enhances camouflage among tree branches and leaves. It is a mildly venomous species, but its toxin poses minimal risk to humans.

·        As an arboreal species, long-snouted vine snake (Ahaetulla longirostris) primarily inhabits trees, allowing it to blend seamlessly into its surroundings.

·        Its rediscovery in Dudhwa highlights the importance of tree-dominated ecosystems in supporting diverse wildlife, including lesser-known reptilian species.

Ecological Importance of Dudhwa Tiger Reserve:

Dudhwa Tiger Reserve, located in the Terai region of Uttar Pradesh near the Indo-Nepal border, comprises Dudhwa National Park, Kishanpur Wildlife Sanctuary, and Katarnia Ghat Wildlife Sanctuary.

·        Established under Project Tiger, the reserve serves as a critical habitat for the Royal Bengal Tiger, Indian rhinoceros, swamp deer, and a variety of bird and reptile species.

·        The rediscovery of long-snouted vine snake underscores the ecological richness of the reserve and highlights the role of microhabitats, such as termite mounds, in supporting rare species. This finding reinforces the significance of sustained research and habitat conservation efforts in the region.

Conclusion

The rediscovery of long-snouted vine snake provides new opportunities for studying its behavior, ecology, and distribution. Further research will help assess its population status, habitat preferences, and interactions with other species. The finding also emphasizes the need to preserve arboreal habitats to ensure the continued survival of lesser-known species within India’s diverse ecosystems.
