West Africa is botanically largely understudied area particular impacted by Global change in the 21st century. The regional natural vegetation ranges from true rain forest on the Atlantic coast in the south, over various types of try forest and savanna to the Sahara desert in the North. Paleogeographic vegetation reconstructions and vegetation modelling suggests that the forest savanna boundary in the region has been particularly dynamic, and subject to cyclic changes in the Pleistocene. The current climatic and land-use change has potential sever effects on regional vegetation, in particular forest species. I am interested in current and past vegetation patterns in West Africa, as well as the current conservation status and anthropogenic use of the flora in the region.
