État de la populationTexte officiel évaluation IUCNExpert

There is no reliable information on the population status of this species. Apparently it is rare and very localised (Rosevear 1974). The most recent confirmed records are from Liberia in the late 1980s (Taylor 1992), but no serious search effort has been undertaken since then. The species has apparently not been reported from bushmeat markets over the past 25 years; this might reflect the limited number of surveys within and around its known range and/or the fact that the arboreal behaviour of this species takes it out of the range of most of the hunting effort.

Description complète des menacesTexte détaillé évaluation IUCNExpert

Like Johnston's Genet (Genetta johnstoni), Bourlon's Genet (G. bourloni) and Liberian Mongoose (Liberiictis kuhni), this species is believed to be affected by ongoing habitat loss in the upper Guinean forests, possibly more so given that it is a canopy species. It is unclear to what degree this semi-arboreal species is impacted by bushmeat hunting, but this could be a threat since most of the specimens collected during field expeditions were acquired from hunters.

It may occur in the Sangbé National Park (NP) in Côte d’Ivoire (Hoppe-Dominik 1990) and the type locality is not far away from the northern boundary of Liberia’s Sapo NP (Schreiber et al. 1989). This is a priority species for further survey work, particularly to determine its current range and population status, whether or not it is subject to damaging levels of hunting, and to investigate other aspects of its ecology. It is presently too poorly known to define relevant conservation needs.
