The transitional semi-evergreen bushland in Ethiopia: characterization and mapping of its distribution using predictive modelling

摘要: Question Evergreen bushlands in Ethiopia have been inadequately studied and mapped. We address the question whether there is a transitional semi-evergreen bushland on eastern escarpment of Ethiopian Highlands, with unique floristic characteristics that distinguish it from evergreen other parts Africa. Methods Based review recent descriptions Ethiopia, we hypothesize distinct zone natural bushland, which restricted to southeastern Highlands. In contrast, are considered be secondary nature. To test this hypothesis, carried out qualitative vegetation surveys 354 locations across classified these based occurrences indicator species. Based data, created predictive distribution models using various environmental models. furthermore compared characteristic species occurrence within Kenya Uganda. Results The confirmed existence type vegetation. The forms between Acacia–Commiphora woodland Afromontane forest escarpments but also characterized by number that, zone. Most not found or only lower densities western Ethiopia. There is, furthermore, limited overlap Uganda. Conclusions Our results provide important information hitherto It highlights character part argue should taken into account for future conservation planning.
