Montserratina becasis

UnknownCREUCREU

Overview

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

Montserratina becasis faces severe threats from volcanic activity on Montserrat, where pyroclastic flows and ash deposits have destroyed much of its native forest habitat. The species' extremely limited range makes it particularly vulnerable to habitat degradation from invasive plant species and ongoing volcanic disturbances. Climate change poses additional risks through altered precipitation patterns that could affect the moist forest conditions this endemic snail requires.

Threat summary

Habitat

This endemic land snail inhabits the moist montane forests of Montserrat's higher elevations, typically found in leaf litter and among native vegetation. The species requires humid microhabitats within the remaining forest fragments that have survived volcanic activity.
