Soil texture and chemical properties of soil dumps, brought up to the surface by the harvester termite Hodotermes mossambicus (Hagen, 1853) during subterranean building activity, were examined and compared with unmodified soils of different depths on three different study areas in the Etosha National Park, northern Namibia. Termites in these regions removed 372.9 kg on a total area of 2595 m(2) between February 1999 and September 2000. These termite-affected soils were enriched in clay, brought up from deeper soil levels richer in day.
