Chamaecrista ulmea
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.
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.
