Chionanthus proctorii

Unknown

Overview

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

Chionanthus proctorii faces severe threats from habitat destruction due to urban development and agricultural expansion across its extremely limited range in Puerto Rico. The species is further threatened by invasive plant species that compete for resources and alter the native forest structure. Hurricane damage poses an additional significant risk to the remaining small populations, as severe storms can destroy mature trees and fragment the already restricted habitat.
