Calliandra glyphoxylon

Unknown

Overview

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

Calliandra glyphoxylon faces severe pressure from agricultural expansion and cattle ranching across its limited range in the Brazilian Cerrado. 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 disrupt the natural savanna dynamics this leguminous shrub depends upon.

Threat summary

Habitat

This endemic Brazilian species inhabits the Cerrado savanna ecosystem, particularly favoring well-drained soils in open woodland areas and grassland margins. It thrives in the transition zones between dense cerrado vegetation and more open campo limpo grasslands, where it benefits from the natural fire cycles that maintain savanna structure.

Why is Calliandra glyphoxylon classified as Endangered?
Calliandra glyphoxylon 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. Calliandra glyphoxylon faces severe pressure from agricultural expansion and cattle ranching across its limited range in the Brazilian Cerrado. 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 disrupt the natural savanna dynamics this leguminous shrub depends upon.
Where does Calliandra glyphoxylon live?
Calliandra glyphoxylon occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
