Phaseolus rosei
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Phaseolus rosei faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range in western Mexico. The species' restricted distribution makes it particularly vulnerable to localized threats, while collection pressure for its edible seeds has further reduced wild populations. Climate change poses an additional threat by altering the precipitation patterns essential for this bean species' reproductive cycle.
Habitat
Phaseolus rosei inhabits tropical deciduous forests and oak-pine woodlands in the Sierra Madre Occidental of western Mexico, typically growing in clearings and forest edges at elevations between 1,200-2,000 meters. The species requires well-drained soils and seasonal rainfall patterns characteristic of these montane ecosystems.
