Robinsonella pilosissima

Declining

Overview

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

Robinsonella pilosissima faces severe pressure from agricultural expansion and urban development across its limited range in Mexico's tropical dry forests. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while cattle grazing and conversion to agricultural land continue to reduce available habitat. Climate change poses an additional threat through altered precipitation patterns that could disrupt the seasonal flowering cycles critical for this endemic shrub's reproduction.

Threat summary

Habitat

This endemic Mexican shrub inhabits tropical dry forests and semi-deciduous woodlands, typically growing in well-drained soils on hillsides and canyon slopes. It occurs at elevations between 200-800 meters in areas with distinct wet and dry seasons.
