Pittosporum leroyanum

Unknown

Overview

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

Pittosporum leroyanum faces severe population decline due to habitat destruction from agricultural expansion and urban development across its limited range in Mauritius. The species is further threatened by invasive plant species that outcompete native vegetation and alter forest composition. Climate change poses additional risks through altered precipitation patterns and increased cyclone intensity, which can damage the fragmented forest patches where remaining populations persist.

Threat summary

Habitat

This endemic Mauritian species inhabits remnant native forest patches and woodland areas, typically found in upland regions with well-drained soils. It occurs in both primary and secondary forest habitats, often along forest edges and in clearings where light penetration allows for growth.

Frequently asked questions

Why is Pittosporum leroyanum classified as Critically Endangered?
Pittosporum leroyanum 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. Pittosporum leroyanum faces severe population decline due to habitat destruction from agricultural expansion and urban development across its limited range in Mauritius. The species is further threatened by invasive plant species that outcompete native vegetation and alter forest composition. Climate change poses additional risks through altered precipitation patterns and increased cyclone intensity, which can damage the fragmented forest patches where remaining populations persist.
Where does Pittosporum leroyanum live?
Pittosporum leroyanum occurs in New Caledonia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pittosporum leroyanum?
The main threats to Pittosporum leroyanum 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.
