Shorea montigena

Declining

Overview

Anthoshorea montigena is a species of plant in the family Dipterocarpaceae. It is a tree native to northeastern Sulawesi and the Maluku Islands in Indonesia.

Shorea montigena faces severe population decline primarily due to extensive logging operations targeting its valuable timber across Borneo's montane forests. Agricultural expansion, particularly oil palm plantations, has fragmented its remaining habitat into isolated patches. Mining activities and infrastructure development have further reduced available habitat, while the species' slow growth rate and specific elevation requirements make natural recovery extremely challenging.

Threat summary

Habitat

Shorea montigena is endemic to the montane dipterocarp forests of Borneo, typically occurring at elevations between 900-1,500 meters. The species requires well-drained soils and thrives in the cooler, humid conditions of these highland tropical forests.

Why is Shorea montigena classified as Critically Endangered?
Shorea montigena is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Shorea montigena faces severe population decline primarily due to extensive logging operations targeting its valuable timber across Borneo's montane forests. Agricultural expansion, particularly oil palm plantations, has fragmented its remaining habitat into isolated patches. Mining activities and infrastructure development have further reduced available habitat, while the species' slow growth rate and specific elevation requirements make natural recovery extremely challenging.
