Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Xenotyphlops grandidieri faces severe threats from Madagascar's rapid deforestation, with primary forests being converted to agricultural land and settlements at an alarming rate. The species' extremely limited distribution makes it particularly vulnerable to habitat fragmentation, as even small-scale forest clearing can eliminate entire local populations. Mining activities and slash-and-burn agriculture in the remaining forest patches pose additional immediate threats to this endemic blind snake's survival.

Threat summary

Habitat

This endemic blind snake inhabits the leaf litter and upper soil layers of Madagascar's remaining primary rainforests, particularly in the eastern humid forests.
