Stereospermum leonense

Unknown

Overview

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

Stereospermum leonense faces severe population decline primarily due to extensive deforestation and agricultural expansion across its limited West African range. The species is particularly vulnerable to logging operations targeting its preferred forest habitats, while slash-and-burn agriculture continues to fragment remaining populations. Climate change compounds these pressures by altering rainfall patterns essential for this tree's reproductive cycles.

Threat summary

Habitat

This critically endangered tree species inhabits lowland tropical rainforests and gallery forests in West Africa, typically growing in well-drained soils along forest edges and clearings. It requires high humidity and consistent rainfall patterns characteristic of Guinea's forest zone ecosystems.

Frequently asked questions

Why is Stereospermum leonense classified as Critically Endangered?
Stereospermum leonense 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. Stereospermum leonense faces severe population decline primarily due to extensive deforestation and agricultural expansion across its limited West African range. The species is particularly vulnerable to logging operations targeting its preferred forest habitats, while slash-and-burn agriculture continues to fragment remaining populations. Climate change compounds these pressures by altering rainfall patterns essential for this tree's reproductive cycles.
Where does Stereospermum leonense live?
Stereospermum leonense occurs in Sierra Leone. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
