Zanthoxylum dumosum

Unknown

Overview

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

Zanthoxylum dumosum is a Critically Endangered shrub confined to a small number of fragmented dry-forest and scrubland localities, making it acutely vulnerable to habitat clearance for agriculture and grazing. Its restricted range and low population size mean that even localized disturbances, such as land conversion or fuelwood collection, can substantially reduce the number of mature individuals. Ongoing degradation of remaining habitat patches limits natural regeneration and gene flow between subpopulations.

Why is Zanthoxylum dumosum classified as Critically Endangered?
Zanthoxylum dumosum 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. Zanthoxylum dumosum is a Critically Endangered shrub confined to a small number of fragmented dry-forest and scrubland localities, making it acutely vulnerable to habitat clearance for agriculture and grazing. Its restricted range and low population size mean that even localized disturbances, such as land conversion or fuelwood collection, can substantially reduce the number of mature individuals. Ongoing degradation of remaining habitat patches limits natural regeneration and gene flow between subpopulations.
Where does Zanthoxylum dumosum live?
