Clusia brittonii

Unknown

Overview

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

Clusia brittonii faces severe threats from urban development and agricultural expansion across its extremely limited range in Puerto Rico. The species' restricted distribution to specific limestone formations makes it particularly vulnerable to habitat fragmentation and complete site destruction. Hurricane damage and invasive plant species further compound the pressures on remaining populations, while the small population size increases vulnerability to stochastic events and genetic bottlenecks.

Threat summary

Habitat

Clusia brittonii is endemic to limestone cliffs and rocky outcrops in the karst regions of northern Puerto Rico. The species requires specific geological conditions and grows in crevices and ledges of limestone formations, often in areas with thin soils and exposed rock faces.

Frequently asked questions

Why is Clusia brittonii classified as Critically Endangered?
Clusia brittonii 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. Clusia brittonii faces severe threats from urban development and agricultural expansion across its extremely limited range in Puerto Rico. The species' restricted distribution to specific limestone formations makes it particularly vulnerable to habitat fragmentation and complete site destruction. Hurricane damage and invasive plant species further compound the pressures on remaining populations, while the small population size increases vulnerability to stochastic events and genetic bottlenecks.
Where does Clusia brittonii live?
Clusia brittonii occurs in Colombia, and Cuba. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Clusia brittonii?
The main threats to Clusia brittonii 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.
