    Question How well does the forest classification system of the 1:5,000,000 vegetation map of Africa developed by Frank White correspond with classification systems and more extensive information on species assemblages of higher resolution maps developed for Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda and Zambia? Methods We reviewed various national and sub-national vegetation maps for their potential in increasing the resolution of the African map. Associated documentation was consulted to compile species assemblages, and to identify indicator species, for national forest vegetation types. Indicator species were identified for each regional forest type by selecting those species that, among all the species listed for the same phytochorion (regional centre of endemism), were listed only for that forest type. For each of the national forest types, we counted the number of indicator species of the anticipated regional type. Floristic relationships (expressed by four different ecological distance measures) among national forest types were investigated based on distance-based redundancy analysis, permutational multivariate analysis of variance (PERMANOVA) using distance matrices and hierarchical clustering.

    In the 50s to 70s of the twenties century vegetation scientists and botanists mapped the vegetation and land cover of most of eastern Africa. These maps offer an unique insight in the vegetation patterns in the region. Unique because they were based on extensive field surveys, often in combination with detailed areal photography studies by experienced field botanists and vegetation scientists. These explorers were usually able to create detailed maps of entire countries, something which has become increasingly more difficult since much larger changes and fragmentation of natural vegetation has taken place in the decades since these maps were developed. The vegetation maps were for long periods hardly utilized outside of plant ecology circles and they became largely forgotten. A plausible explanation for the lack of interest in the vegetation maps is that during the period following the completion of the vegetation maps, there was little interest in indigenous vegetation outside of national parks and forest reserves. The main species used for e.g. industrial forest plantations and social forestry woodlots were the species that had been established by the forestry services during the colonial era – mainly Central American Pinus and Australian Eu
