Rhaptopetalum rabiense

Unknown

Overview

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

Rhaptopetalum rabiense faces severe threats from deforestation and agricultural expansion within its extremely limited range in Cameroon's Cross-Sanaga-Bioko coastal forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while logging activities continue to reduce the quality of remaining forest patches. Climate change poses an additional long-term threat through altered precipitation patterns affecting the humid forest conditions this species requires.

Threat summary

Frequently asked questions

Why is Rhaptopetalum rabiense classified as Critically Endangered?
Rhaptopetalum rabiense is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Rhaptopetalum rabiense faces severe threats from deforestation and agricultural expansion within its extremely limited range in Cameroon's Cross-Sanaga-Bioko coastal forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while logging activities continue to reduce the quality of remaining forest patches. Climate change poses an additional long-term threat through altered precipitation patterns affecting the humid forest conditions this species requires.
Where does Rhaptopetalum rabiense live?
Rhaptopetalum rabiense occurs in Gabon. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Rhaptopetalum rabiense?
The main threats to Rhaptopetalum rabiense are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
