Chamaecrista guanensis

Unknown

Overview

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

Chamaecrista guanensis faces severe threats from agricultural expansion and cattle ranching across its extremely limited range in the Guiana Highlands. Mining activities, particularly for gold and diamonds, have degraded critical habitat areas through soil disturbance and water contamination. The species' restricted distribution makes it exceptionally vulnerable to localized habitat destruction, with entire populations potentially eliminated by single development projects.

Threat summary

Habitat

This leguminous shrub is endemic to the tepuis and montane regions of the Guiana Highlands, occurring in sandy soils and rocky outcrops at elevations between 800-1,500 meters. It typically grows in open savanna-like environments and forest edges where drainage is excellent and soils are nutrient-poor.
