Abstract
An Index of Biological Integrity (IBI) has been developed for rangeland condition assessment in arid
northwestern Namibia. The usefulness of termites as bio-indlcators has been tested and reliable
sampling protocol for termite diversity in an arid ervlronrnent has been developed. The study was
conducted mainly at a high- and low-intensity site on each of three farms. Two of the farms were
communally owned; the other was commercially owned. (Abbreviation abstract)
