Ailanthus vietnamensis

Unknown

Overview

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

Ailanthus vietnamensis faces severe population decline due to extensive deforestation and habitat conversion in its native Vietnamese range. The species is particularly vulnerable to logging operations and agricultural expansion that fragment its remaining forest habitat. Urban development and infrastructure projects have further reduced available habitat, while the small remaining population size makes the species extremely susceptible to stochastic events and genetic bottlenecks.

Threat summary

Habitat

This critically endangered tree species is endemic to the tropical forests of Vietnam, where it occurs in lowland and montane forest ecosystems. It typically grows in primary and secondary forest habitats with well-drained soils and high humidity levels characteristic of Southeast Asian tropical forests.

Frequently asked questions

Why is Ailanthus vietnamensis classified as Critically Endangered?
Ailanthus vietnamensis 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. Ailanthus vietnamensis faces severe population decline due to extensive deforestation and habitat conversion in its native Vietnamese range. The species is particularly vulnerable to logging operations and agricultural expansion that fragment its remaining forest habitat. Urban development and infrastructure projects have further reduced available habitat, while the small remaining population size makes the species extremely susceptible to stochastic events and genetic bottlenecks.
Where does Ailanthus vietnamensis live?
Ailanthus vietnamensis occurs in Vietnam. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Ailanthus vietnamensis?
The main threats to Ailanthus vietnamensis are 3.2, 5.3, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
