Description complète des menacesTexte détaillé évaluation IUCNExpert
This species is endemic to Zambia, where it is known to occur in the Copperbelt, Central and Lusaka Provinces. In Zambia, the estimated rate of conversion of land to urban use is 3.2% per annum, and the annual rate of deforestation is in the range of 1.5–6% (Mabeta et al. 2018). Urbanisation is a particular threat where this species is found in the outskirts of Lusaka and large amounts of habitat have already been lost to settlements and intensive agriculture (Google Earth 2022). Similarly, Ndola has also been expanding, with heavily transformed habitats visible from satellite imagery (Google Earth 2022). The Ndola area, within the Copperbelt Province, is the most significant mining district in Zambia, with concessions covering over 200,000 hectares (Kambani 2003, Global Forest Watch 2022).
