Psiadia cataractae

Declining

Overview

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

Psiadia cataractae faces severe threats from habitat destruction due to urban development and agricultural expansion on Mauritius. The species' extremely limited range makes it particularly vulnerable to invasive plant species that outcompete native vegetation. Climate change poses additional risks through altered precipitation patterns affecting the moist forest conditions this endemic shrub requires.

Threat summary

Habitat

This endemic Mauritian shrub inhabits moist upland forests and forest margins, typically growing in areas with consistent moisture and partial shade. It occurs in remnant native forest patches that have largely been fragmented by human activities.
