Geranium exallum

Unknown

Overview

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

Geranium exallum faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Invasive plant species compete directly with this geranium for resources, while climate change alters the specific moisture and temperature conditions it requires for reproduction.

Threat summary

Habitat

Geranium exallum inhabits rocky slopes, cliff faces, and well-drained soils in montane and subalpine regions. The species typically grows in open areas with partial shade, requiring specific soil chemistry and drainage conditions found in its native mountainous terrain.
