Monoon glabrum

Unknown

Overview

Monoon glabrum is a species of plants in the custard apple family Annonaceae. It is a tree endemic to Peninsular Malaysia and is threatened by habitat loss.

Monoon glabrum faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion and urban development across its native range in Southeast Asia. The species' restricted distribution and specialized habitat requirements make it particularly vulnerable to forest fragmentation, while selective logging targets mature trees that provide essential breeding and foraging sites.

Threat summary

Habitat

Monoon glabrum inhabits tropical lowland rainforests and secondary forest areas, typically occurring in well-drained soils of river valleys and hillsides. The species requires mature forest canopy cover and is associated with mixed dipterocarp forest communities at elevations below 800 meters.

Frequently asked questions

Why is Monoon glabrum classified as Critically Endangered?
Monoon glabrum 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. Monoon glabrum faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion and urban development across its native range in Southeast Asia. The species' restricted distribution and specialized habitat requirements make it particularly vulnerable to forest fragmentation, while selective logging targets mature trees that provide essential breeding and foraging sites.
Where does Monoon glabrum live?
Monoon glabrum occurs in Malaysia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Monoon glabrum?
The main threats to Monoon glabrum are 1.1, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
