Phaseolus rosei

Unknown

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.

Threat summary

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.

Frequently asked questions

Why is Phaseolus rosei classified as Endangered?
Phaseolus rosei 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. 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.
Where does Phaseolus rosei live?
Phaseolus rosei occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Phaseolus rosei?
The main threats to Phaseolus rosei are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
