Ilex subtriflora

Unknown

Overview

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

Ilex subtriflora faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range in southeastern Brazil. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Invasive plant species further degrade the quality of remaining forest patches, while climate change poses additional stress through altered precipitation patterns affecting the humid forest conditions this holly requires.

Threat summary

Habitat

Ilex subtriflora inhabits humid Atlantic Forest remnants in southeastern Brazil, typically found in understory and edge environments of montane and submontane forests. The species requires well-drained soils and consistent moisture levels characteristic of Brazil's threatened Atlantic Forest biome.

Frequently asked questions

Why is Ilex subtriflora classified as Critically Endangered?
Ilex subtriflora 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. Ilex subtriflora faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range in southeastern Brazil. The species' restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Invasive plant species further degrade the quality of remaining forest patches, while climate change poses additional stress through altered precipitation patterns affecting the humid forest conditions this holly requires.
Where does Ilex subtriflora live?
Ilex subtriflora occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
