Monadenia setosa

Unknown

Overview

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

Monadenia setosa faces severe habitat degradation from urban development and agricultural conversion throughout its limited California range. The species is particularly vulnerable to drought conditions that desiccate its forest floor microhabitats, while invasive plant species alter the leaf litter composition essential for its survival. Fire suppression practices have also modified the natural forest structure, reducing the cool, moist understory conditions this terrestrial snail requires.

Threat summary

Habitat

This terrestrial snail inhabits the cool, moist understory of mixed coniferous and deciduous forests in coastal California, particularly favoring areas with deep leaf litter and fallen logs. It requires stable microhabitats with consistent moisture levels and is typically found in elevations ranging from sea level to approximately 1,500 meters.
