Acer chiangdaoense

Unknown

Overview

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

Acer chiangdaoense faces severe pressure from limestone quarrying operations that directly destroy its specialized karst habitat in northern Thailand. The species' extremely limited range, restricted to a few limestone hills around Chiang Dao, makes it particularly vulnerable to habitat conversion and fragmentation. Agricultural expansion and infrastructure development in the surrounding valleys further isolate remaining populations.

Threat summary

Habitat

This endemic maple species inhabits limestone karst formations and rocky outcrops in montane forests of northern Thailand, typically growing in crevices and on steep limestone cliffs between 400-1,200 meters elevation. It requires the specific microclimate and soil conditions created by weathered limestone substrates.

Frequently asked questions

Why is Acer chiangdaoense classified as Endangered?
Acer chiangdaoense is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Acer chiangdaoense faces severe pressure from limestone quarrying operations that directly destroy its specialized karst habitat in northern Thailand. The species' extremely limited range, restricted to a few limestone hills around Chiang Dao, makes it particularly vulnerable to habitat conversion and fragmentation. Agricultural expansion and infrastructure development in the surrounding valleys further isolate remaining populations.
Where does Acer chiangdaoense live?
Acer chiangdaoense occurs in Myanmar (Burma), Thailand, and Vietnam. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Acer chiangdaoense?
The main threats to Acer chiangdaoense 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.
