Senna formosa

Unknown

Overview

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

Senna formosa faces significant pressure from agricultural expansion and cattle ranching across its native range in the Brazilian Cerrado. Urban development and infrastructure projects have fragmented remaining populations, while altered fire regimes disrupt the natural savanna cycles this species depends upon. Climate change compounds these pressures by shifting precipitation patterns critical for seed germination and establishment.

Threat summary

Habitat

Senna formosa inhabits the Brazilian Cerrado savanna, thriving in open grasslands with scattered trees and gallery forests. This species prefers well-drained soils and areas with natural fire cycles that maintain the characteristic savanna structure.
