Pyrostria revoluta

Declining

Overview

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

Pyrostria revoluta faces severe threats from ongoing deforestation and habitat degradation across its limited range in Madagascar's eastern rainforests. The species' extremely restricted distribution makes it particularly vulnerable to localized habitat destruction from slash-and-burn agriculture, logging, and human settlement expansion. Climate change poses additional pressure through altered precipitation patterns that could affect the humid forest conditions this endemic shrub requires for survival.

Threat summary

Habitat

Pyrostria revoluta is endemic to Madagascar's eastern humid rainforests, where it grows as an understory shrub in primary and secondary forest habitats. The species requires the consistently moist, shaded conditions typical of Madagascar's eastern escarpment forests at mid-elevations.
