Gaertnera grisea

Declining

Overview

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

Gaertnera grisea faces significant pressure from habitat degradation in its limited range within Madagascar's eastern rainforests. Slash-and-burn agriculture and logging activities continue to fragment the remaining forest patches where this endemic shrub occurs. The species' restricted distribution makes it particularly vulnerable to localized disturbances, with climate change potentially altering the moisture regimes essential for its survival in montane forest environments.

Threat summary

Habitat

Gaertnera grisea is endemic to the humid montane forests of eastern Madagascar, typically occurring in understory environments at elevations between 800-1,500 meters. The species requires the consistent moisture and filtered light conditions characteristic of intact rainforest ecosystems.
