Pinanga sibuyanensis

Declining

Overview

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

Pinanga sibuyanensis faces severe threats from deforestation and habitat conversion on Sibuyan Island, where its entire population is confined to rapidly diminishing forest fragments. Mining activities and agricultural expansion have dramatically reduced the species' already limited habitat, while the small population size makes it extremely vulnerable to stochastic events and genetic bottlenecks. The species' restricted range on a single island compounds these threats, as any localized disturbance could potentially eliminate entire subpopulations.

Threat summary

Habitat

This endemic palm species inhabits the remaining primary and secondary lowland forests of Sibuyan Island in the Philippines, typically found in moist, shaded understory environments at elevations up to 500 meters. The species requires intact forest canopy cover and appears to be particularly associated with well-drained forest soils in areas with consistent moisture levels.

Frequently asked questions

Why is Pinanga sibuyanensis classified as Critically Endangered?
Pinanga sibuyanensis 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. Pinanga sibuyanensis faces severe threats from deforestation and habitat conversion on Sibuyan Island, where its entire population is confined to rapidly diminishing forest fragments. Mining activities and agricultural expansion have dramatically reduced the species' already limited habitat, while the small population size makes it extremely vulnerable to stochastic events and genetic bottlenecks. The species' restricted range on a single island compounds these threats, as any localized disturbance could potentially eliminate entire subpopulations.
Where does Pinanga sibuyanensis live?
Pinanga sibuyanensis occurs in Philippines. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pinanga sibuyanensis?
The main threats to Pinanga sibuyanensis are 5.1, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
