Heptapleurum curranii

Declining

Overview

Heptapleurum curranii is a species of plant in the family Araliaceae. It is a scrambling shrub or small tree endemic to the island of Palawan in the Philippines.

Heptapleurum curranii faces severe threats from ongoing deforestation and habitat conversion in its limited range within the Philippines. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, with logging activities and agricultural expansion continuing to fragment and destroy its remaining forest habitat. Climate change poses an additional threat through altered precipitation patterns and increased frequency of extreme weather events that could further stress the remaining populations.

Threat summary

Habitat

This endemic Philippine species inhabits primary and secondary tropical rainforests, typically found in the understory and mid-canopy layers of montane and lowland forest ecosystems. It requires intact forest cover with high humidity and stable microclimatic conditions characteristic of undisturbed tropical forest environments.
