Rinorea thomensis

Unknown

Overview

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

Rinorea thomensis faces significant pressure from habitat degradation on São Tomé Island, where its lowland forest habitat is increasingly fragmented by agricultural expansion and human settlement. The species' restricted range makes it particularly vulnerable to localized threats, with deforestation for cocoa plantations and subsistence farming reducing available habitat. Climate change poses an additional long-term threat, as rising temperatures may force this lowland species to seek higher elevations where suitable habitat is limited.
