Threats and conservation strategies for the African cherry (Prunus africana) in its natural range- A review

摘要

The world’s?Prunus africana?bark demand used to be satisfied by exports, approximately 4000 tonnes per year from a few African countries, led by Cameroon exporting 62%, Madagascar, 20% and Uganda and Equatorial Guinea, 7% each. This coupled with unsustainable bark harvesting methods created pressure on the natural resource which suffered population decline and resulted in the species listing in Appendix II of CITES and EU’s bark export ban. In other range countries where no commercial harvesting has taken place, the species is under threat from other anthropogenic threats which include local use, deforestation and habitat fragmentation which is affecting populations in Ethiopia, Madagascar, Zimbabwe and South Africa as well as Cameroon, Uganda and Equatorial Guinea. Wildfires burn?P. africana?seedlings, saplings and mature trees throughout the species’ range every year. Invasive alien species have mainly affected?P. africanapopulations in Zimbabwe and South Africa. Climate change is projected to affect populations in southern Africa and Madagascar than those in East and West Africa. The fact that the threats vary or are common among countries calls for different or similar?P. africana?conservation strategies respectively. Strategies may vary from country to country or region to region depending on the type and magnitude of threats. These strategies include?in situ, circa situ?and?ex situ?conservation. In this paper, the various threats to?P. africana?populations across the species’ natural range are investigated together with the conservation strategies which can be put in place to ensure sustainability.
