Weinmannia jahnii

Declining

Overview

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

Weinmannia jahnii faces severe pressure from ongoing deforestation and habitat fragmentation across its limited Venezuelan range. Agricultural expansion and urban development continue to reduce the montane forest areas essential for this endemic tree's survival. Climate change poses an additional threat by altering the specific temperature and moisture conditions required in its high-altitude habitat.

Threat summary

Habitat

This endemic Venezuelan tree species inhabits montane cloud forests and humid mountain slopes at elevations between 1,500-2,500 meters. It requires the specific microclimate conditions found in these high-altitude tropical forests, including consistent moisture and cooler temperatures.
