Sophora mangarevaensis

Declining

Overview

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

Sophora mangarevaensis faces severe threats from invasive plant species that outcompete native vegetation and alter soil chemistry on Mangareva Island. Habitat degradation from introduced grazing animals, particularly goats and pigs, has severely impacted the remaining forest fragments where this endemic tree survives. The species' extremely limited population size and restricted range make it highly vulnerable to stochastic events and genetic bottlenecks.

Threat summary

Sophora mangarevaensis faces severe threats from invasive plant species that outcompete native vegetation and alter soil chemistry on Mangareva Island. Habitat degradation from introduced grazing animals, particularly goats and pigs, has severely impacted the remaining forest fragments where this endemic tree survives. The species' extremely limited population size and restricted range make it highly vulnerable to stochastic events and genetic bottlenecks.
Where does Sophora mangarevaensis live?
Sophora mangarevaensis occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
