s:950:"%T Comparisons between original and current composition of indigenous tree species around Mount Kenya %A Kindt, R. %A Lillesø, J-P.B. %A van, Breugel.P. %X Tropical trees are sedentary for most of their lifespan and spatial distribution data are available for many plant species (e.g. McClean et al. 2005). However little is known of the ecology and distribution of the majority of African tree species. Only a small fraction of terrestrial species has been described to date and fine-scale distributional data are available only for a few species. As such global assessments of biodiversity distribution have been based on surrogates such as ranges of vertebrate species or ecoregions (Ferrier et al. 2002 2004). One such ecoregional map that has been used within the context of global biodiversity assessment (Olson et al. 2001) is the vegetation map of Africa showing boundaries for continental patterns of plant endemism (White 1983).
