Cojoba urbanii

Declining

Overview

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

Cojoba urbanii faces severe threats from ongoing deforestation and habitat conversion in its extremely limited range within Puerto Rico's remaining forest fragments. The species' restricted distribution makes it particularly vulnerable to localized disturbances, including infrastructure development and invasive species encroachment. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this endemic tree requires for survival and reproduction.

Threat summary

Habitat

Cojoba urbanii is endemic to Puerto Rico's moist limestone forests, typically found in karst terrain with well-drained soils. The species occurs in secondary forest fragments and forest edges, often in areas with partial canopy cover where it can access adequate light while maintaining the humid conditions necessary for establishment.

Frequently asked questions

Why is Cojoba urbanii classified as Critically Endangered?
Cojoba urbanii 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. Cojoba urbanii faces severe threats from ongoing deforestation and habitat conversion in its extremely limited range within Puerto Rico's remaining forest fragments. The species' restricted distribution makes it particularly vulnerable to localized disturbances, including infrastructure development and invasive species encroachment. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this endemic tree requires for survival and reproduction.
Where does Cojoba urbanii live?
Cojoba urbanii occurs in Dominican Republic. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cojoba urbanii?
The main threats to Cojoba urbanii 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.
