Pterospermum menglunense

Unknown

Overview

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

Pterospermum menglunense faces severe population decline primarily due to rapid deforestation and habitat conversion in its limited range within tropical China. The species' extremely restricted distribution makes it particularly vulnerable to localized threats, with agricultural expansion and infrastructure development fragmenting remaining forest patches. Climate change poses additional pressure through altered precipitation patterns affecting the humid forest conditions this tree requires for reproduction and survival.

Threat summary

Habitat

This critically endangered tree species inhabits humid tropical forests in southwestern China, typically growing in lowland and montane forest ecosystems. It requires specific microclimate conditions with high humidity and consistent moisture levels found in undisturbed primary forest environments.

Why is Pterospermum menglunense classified as Critically Endangered?
Pterospermum menglunense 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. Pterospermum menglunense faces severe population decline primarily due to rapid deforestation and habitat conversion in its limited range within tropical China. The species' extremely restricted distribution makes it particularly vulnerable to localized threats, with agricultural expansion and infrastructure development fragmenting remaining forest patches. Climate change poses additional pressure through altered precipitation patterns affecting the humid forest conditions this tree requires for reproduction and survival.
Where does Pterospermum menglunense live?
Pterospermum menglunense occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
