Popis: Samples of vegetation revealed that total plant biomass was reduced by almost 30% directly above burrows of mole-rats (Bathyergidae) compared with control samples. Bulbs and roots of dicots especially were reduced above burrows. We predicted that mole-rats would inhabit portions of the study site with greater than average plant biomass than indicated by random samples on the field site; this was not the case. Burrows underlay 10.7% of the study area and mounds produced during excavation of burrows covered another 28.2% of the field. Thus, the potential impact of burrowing activity of mole-rats on the plant community is substantial, through both direct consumption of plant material and physical alteration of the habitat.
