Vegetation along climate gradients in Kaokoland, North-West Namibia
Becker, Thorsten; Jürgens, Norbert
Vegetation ecological research was conducted in Kaokoland along three transects during the rainy seasons of 1997 and 1998. The transects follow the predominately east-west leading gradients of decreasing precipitation and increasing variability in rainfall. A total of 387 relevés was recorded in order to describe the diversity of the vegetation along the transects. Besides the gradient of climate elements edaphic and topographic factors have a strong influence on vegetation patterns. Furthermore, the pastoral utilisation by semi-nomadic Herero-speaking people has an impact on the vegetation. Fortyfive plant communities were derived from 4 identified main vegetation units. These vegetation units comprise different types of savannas and ephemeral grasslands. The classification of vegetation units and communities is presented in several tables. Using the whole data set, the influence of precipitation on the vegetation units was analysed using ordination techniques.
