Calliandra pilosa

Unknown

Overview

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

Calliandra pilosa faces significant pressure from agricultural expansion and cattle ranching across its native range in the Atlantic Forest and Cerrado regions of Brazil. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. Urban development and infrastructure projects continue to encroach on the species' remaining strongholds, while altered fire regimes in degraded areas prevent successful seedling establishment.

Threat summary

Habitat

This leguminous shrub occurs in gallery forests, forest edges, and open woodland areas within Brazil's Atlantic Forest and Cerrado biomes. It typically grows in well-drained soils along riverbanks and in transitional zones between forest and grassland ecosystems.
