Ilex arisanensis

Unknown

Overview

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

Ilex arisanensis faces severe pressure from habitat destruction as Taiwan's montane forests are cleared for agriculture and development. The species' restricted range makes it particularly vulnerable to localized disturbances, while climate change threatens to shift suitable habitat zones upslope beyond the species' current elevational limits. Small population size increases extinction risk from stochastic events and reduces genetic diversity.

Threat summary

Habitat

This endemic holly species inhabits montane broadleaf forests and forest margins in Taiwan's central mountain ranges, typically occurring at elevations between 1,500-2,500 meters. It grows in cool, humid conditions among mixed deciduous and evergreen forest communities.

Frequently asked questions

Why is Ilex arisanensis classified as Endangered?
Ilex arisanensis 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. Ilex arisanensis faces severe pressure from habitat destruction as Taiwan's montane forests are cleared for agriculture and development. The species' restricted range makes it particularly vulnerable to localized disturbances, while climate change threatens to shift suitable habitat zones upslope beyond the species' current elevational limits. Small population size increases extinction risk from stochastic events and reduces genetic diversity.
Where does Ilex arisanensis live?
Ilex arisanensis occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Ilex arisanensis?
The main threats to Ilex arisanensis 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.
