Monadenia circumcarinata
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Monadenia circumcarinata faces severe habitat degradation from urban development and agricultural expansion 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 conditions this terrestrial snail requires.
Habitat
This terrestrial snail inhabits the cool, moist leaf litter and understory of mixed coniferous and deciduous forests in coastal California. It requires specific microhabitat conditions with high humidity, stable temperatures, and rich organic matter for feeding and reproduction.
