Oreopanax williamsii

Unknown

Overview

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

Oreopanax williamsii faces severe pressure from ongoing deforestation and agricultural expansion throughout its limited montane range in Central America. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Climate change poses an additional threat by potentially shifting suitable habitat zones upslope, reducing the total area of appropriate montane conditions.

Threat summary

Habitat

This endemic tree species inhabits cloud forests and montane rainforests at elevations between 1,200-2,400 meters in the mountains of Costa Rica and Panama. It requires the consistently humid conditions and stable temperatures characteristic of these high-altitude tropical ecosystems.
