Vigna dolomitica

Declining

Overview

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

Vigna dolomitica faces severe threats from limestone quarrying and mining activities that directly destroy its specialized dolomitic limestone habitat. The species' extremely restricted range on specific geological formations makes it particularly vulnerable to habitat fragmentation and complete site destruction. Agricultural expansion and infrastructure development in the surrounding areas further reduce available habitat and create edge effects that degrade remaining populations.

Threat summary

Habitat

This critically endangered legume is endemic to dolomitic limestone outcrops and rocky slopes with alkaline soils. It occupies specialized microhabitats on exposed limestone formations where few other plant species can survive the harsh, mineral-rich conditions.

Frequently asked questions

Why is Vigna dolomitica classified as Critically Endangered?
Vigna dolomitica 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. Vigna dolomitica faces severe threats from limestone quarrying and mining activities that directly destroy its specialized dolomitic limestone habitat. The species' extremely restricted range on specific geological formations makes it particularly vulnerable to habitat fragmentation and complete site destruction. Agricultural expansion and infrastructure development in the surrounding areas further reduce available habitat and create edge effects that degrade remaining populations.
Where does Vigna dolomitica live?
Vigna dolomitica occurs in Angola, Congo - Brazzaville, and Congo - Kinshasa. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Vigna dolomitica?
The main threats to Vigna dolomitica 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.
