Horsfieldia sessilifolia

Unknown

Overview

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

Horsfieldia sessilifolia faces severe population decline primarily due to extensive deforestation and habitat conversion throughout its limited range in Southeast Asian lowland forests. Agricultural expansion, particularly oil palm plantations and logging operations, has fragmented the remaining forest patches where this endemic nutmeg species occurs. The species' restricted distribution and specialized habitat requirements make it extremely vulnerable to continued forest loss, with remaining populations increasingly isolated in small, degraded forest remnants.

Threat summary

Habitat

Horsfieldia sessilifolia is endemic to lowland tropical rainforests, typically occurring in primary and secondary forest habitats at elevations below 500 meters. The species requires the humid, shaded understory conditions characteristic of intact dipterocarp forests in Southeast Asia.

Why is Horsfieldia sessilifolia classified as Critically Endangered?
Horsfieldia sessilifolia 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. Horsfieldia sessilifolia faces severe population decline primarily due to extensive deforestation and habitat conversion throughout its limited range in Southeast Asian lowland forests. Agricultural expansion, particularly oil palm plantations and logging operations, has fragmented the remaining forest patches where this endemic nutmeg species occurs. The species' restricted distribution and specialized habitat requirements make it extremely vulnerable to continued forest loss, with remaining populations increasingly isolated in small, degraded forest remnants.
Where does Horsfieldia sessilifolia live?
Horsfieldia sessilifolia occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
