Micrarionta gabbii

Unknown

Overview

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

Micrarionta gabbii faces severe habitat degradation from urban development and agricultural expansion across its limited Southern California range. The species is particularly vulnerable to drought conditions and altered fire regimes that destroy the shrubland vegetation it depends upon. Invasive plant species further degrade habitat quality by outcompeting native flora that provides essential food sources and shelter.
