Rustia angustifolia

Declining

Overview

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

Rustia angustifolia faces severe pressure from deforestation and agricultural expansion throughout its limited range in Central American cloud forests. The species' narrow altitudinal requirements make it particularly vulnerable to climate change, as warming temperatures force suitable habitat upslope into increasingly fragmented patches. Mining activities and infrastructure development further fragment the remaining forest corridors essential for population connectivity.

Threat summary

Habitat

Rustia angustifolia is endemic to montane cloud forests between 1,200-2,400 meters elevation in Central America. The species requires the persistent moisture and stable temperatures characteristic of these fog-shrouded ecosystems, typically growing in the understory of primary and well-developed secondary forests.

Frequently asked questions

Why is Rustia angustifolia classified as Endangered?
Rustia angustifolia 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. Rustia angustifolia faces severe pressure from deforestation and agricultural expansion throughout its limited range in Central American cloud forests. The species' narrow altitudinal requirements make it particularly vulnerable to climate change, as warming temperatures force suitable habitat upslope into increasingly fragmented patches. Mining activities and infrastructure development further fragment the remaining forest corridors essential for population connectivity.
Where does Rustia angustifolia live?
Rustia angustifolia 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 Rustia angustifolia?
The main threats to Rustia angustifolia 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.
