Hibbertia margaretae

Unknown

Overview

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

Hibbertia margaretae faces severe threats from urban development and infrastructure expansion across its limited range in Western Australia. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation from residential and commercial development. Mining activities and road construction pose additional pressures on remaining populations, while altered fire regimes and invasive plant species further degrade suitable habitat.

Threat summary
