Stemonoporus moonii

Unknown

Overview

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

Stemonoporus moonii faces severe population decline primarily due to extensive deforestation and habitat conversion throughout Sri Lanka's lowland wet zone forests. The species is particularly vulnerable to logging operations and agricultural expansion, as it requires intact forest canopy structure for survival. Mining activities and infrastructure development have further fragmented its already limited range, while climate change threatens to alter the specific moisture and temperature conditions this endemic tree species requires.

Threat summary

Habitat

Stemonoporus moonii is endemic to Sri Lanka's lowland wet zone rainforests, typically occurring in primary and mature secondary forest formations at elevations below 500 meters. The species requires high humidity levels and consistent rainfall patterns characteristic of these tropical wet forests, growing as part of the forest canopy structure.

Frequently asked questions

Why is Stemonoporus moonii classified as Critically Endangered?
Stemonoporus moonii 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. Stemonoporus moonii faces severe population decline primarily due to extensive deforestation and habitat conversion throughout Sri Lanka's lowland wet zone forests. The species is particularly vulnerable to logging operations and agricultural expansion, as it requires intact forest canopy structure for survival. Mining activities and infrastructure development have further fragmented its already limited range, while climate change threatens to alter the specific moisture and temperature conditions this endemic tree species requires.
Where does Stemonoporus moonii live?
Stemonoporus moonii occurs in Sri Lanka. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Stemonoporus moonii?
The main threats to Stemonoporus moonii are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
