Zanthoxylum bissei

Unknown

Overview

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

Zanthoxylum bissei faces severe population decline due to extensive deforestation and agricultural conversion of its native Cuban forest habitats. The species' extremely limited range makes it particularly vulnerable to habitat fragmentation, while its slow growth rate and specific ecological requirements hinder natural recovery. Urban development and infrastructure expansion continue to reduce the remaining forest patches where this endemic tree survives.

Threat summary

Habitat

This endemic Cuban tree species inhabits tropical dry forests and semi-deciduous woodlands at low to moderate elevations. It typically grows in well-drained soils on limestone substrates characteristic of Cuba's coastal and inland forest ecosystems.
