Neisosperma sevenetii

Declining

Overview

Ochrosia sevenetii, synonym Neisosperma sevenetii, is a species of flowering plant in the family Apocynaceae. It is endemic to New Caledonia, where it is known from only two sites. Its habitat is threatened with encroachment and fire.

Neisosperma sevenetii faces severe threats from habitat destruction due to coastal development and agricultural expansion across its limited range in New Caledonia. The species is particularly vulnerable to invasive plant species that compete for resources and alter the native ecosystem structure. Mining activities in the region pose additional pressure through direct habitat loss and soil contamination, while climate change threatens to alter the specific environmental conditions this endemic species requires for survival.

Threat summary

Habitat

This endemic New Caledonian species inhabits coastal forests and shrublands, typically found in well-drained soils on slopes and ridges. It occurs in both primary and secondary forest environments, often associated with ultramafic substrates characteristic of New Caledonia's unique geological formations.

Frequently asked questions

Why is Neisosperma sevenetii classified as Critically Endangered?
Neisosperma sevenetii 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. Neisosperma sevenetii faces severe threats from habitat destruction due to coastal development and agricultural expansion across its limited range in New Caledonia. The species is particularly vulnerable to invasive plant species that compete for resources and alter the native ecosystem structure. Mining activities in the region pose additional pressure through direct habitat loss and soil contamination, while climate change threatens to alter the specific environmental conditions this endemic species requires for survival.
Where does Neisosperma sevenetii live?
Neisosperma sevenetii 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 Neisosperma sevenetii?
The main threats to Neisosperma sevenetii are 3.2, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
