Sideroxylon nadeaudii

Declining

Overview

Sideroxylon nadeaudii is a species of plant in the family Sapotaceae. It is endemic to Tahiti, French Polynesia.

Sideroxylon nadeaudii faces severe population decline due to extensive habitat destruction from urban development and agricultural expansion across its limited range in Mauritius. Invasive plant species have fundamentally altered the native forest composition, outcompeting this endemic tree for resources and space. The species' extremely small population size makes it highly vulnerable to stochastic events and genetic bottlenecks that could drive it to extinction.

Threat summary

Habitat

This endemic Mauritian tree inhabits remnant patches of native lowland and upland forests, typically growing in well-drained soils on volcanic slopes. It occurs in both dry and semi-humid forest zones, often associated with other native Mascarene flora in increasingly fragmented forest remnants.

Frequently asked questions

Why is Sideroxylon nadeaudii classified as Critically Endangered?
Sideroxylon nadeaudii 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. Sideroxylon nadeaudii faces severe population decline due to extensive habitat destruction from urban development and agricultural expansion across its limited range in Mauritius. Invasive plant species have fundamentally altered the native forest composition, outcompeting this endemic tree for resources and space. The species' extremely small population size makes it highly vulnerable to stochastic events and genetic bottlenecks that could drive it to extinction.
Where does Sideroxylon nadeaudii live?
Sideroxylon nadeaudii occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Sideroxylon nadeaudii?
The main threats to Sideroxylon nadeaudii 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.
