Description complète des menacesTexte détaillé évaluation IUCNExpert

The most significant threats are associated with habitat degradation as a consequence of increasing human activities, such as the building of houses, farms and plantations. This is especially true near Freetown, where most of specimens were collected. However, there are still well preserved sandy habitats in south-eastern Sierra Leone, where the species might occur.

Habitats préférentiels (classification IUCN)

5_8Wetlands (inland) - Seasonal/Intermittent Freshwater Marshes/Pools (under 8ha)

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

More surveys are needed near the Peninsula Mountains and central Sierra Leone to evaluate the status of this species. Most of the formerly known localities are destroyed, but some small areas (square metres) of natural habitats are suitable for this species.
