Quantified range condition assessment of open Camelthorn savanna along a degradation gradient
Measurements were taken at 20 different sites in a relatively homogenous area of open Camelthorn savanna in eastern Namibia. Ordination of grass species composition did not provide a good degradation gradient, due to domination by different species of annual grasses at many of the sites. However a centred PCA ordination of perennial grass species indicated a degradation gradient. This gradient was used to allocate a range condition score to each site, which was then correlated with other measurements. Keywords: ordination, distance measurements, Namibian rangeland, western Kalahari.
