Chamaecrista ulmea

Declining

Overview

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

Chamaecrista ulmea faces severe pressure from agricultural expansion and cattle ranching across its limited range in Brazil's Cerrado savanna. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. Fire regime alterations, both suppression and increased frequency from human activities, disrupt the species' natural reproductive cycles and seedling establishment.

Threat summary

Habitat

This leguminous shrub is endemic to the Cerrado savanna of central Brazil, typically found in open grasslands with scattered trees and gallery forest edges. It thrives in well-drained sandy soils and areas with natural fire cycles that maintain the open savanna structure.

Why is Chamaecrista ulmea classified as Endangered?
Chamaecrista ulmea is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Chamaecrista ulmea faces severe pressure from agricultural expansion and cattle ranching across its limited range in Brazil's Cerrado savanna. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. Fire regime alterations, both suppression and increased frequency from human activities, disrupt the species' natural reproductive cycles and seedling establishment.
Where does Chamaecrista ulmea live?
Chamaecrista ulmea occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Chamaecrista ulmea?
The main threats to Chamaecrista ulmea 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.
