Notes on small mammals on the Springbok Flats, Transvaal

Abstract

Small mammals were trapped at three-month intervals on six trap-lines on the Springbok Flats, Transvaal during 1977 and 1978. Trapping success varied considerably (average 18,5%) during 5 760 trap-nights. Nine rodent and four shrew species were recorded in the area. Species composition and abundance differed on black turf and red clay. Praomys natalensis, Rhabdomys pumilio and Otomys angoniensis were the dominant rodents, and Crocidura hirta the commonest shrew. Trapping success was greatest in late spring and autumn to mid-winter. O. angoniensis probably bred throughout the year, but P. natalensis and ft pumilio produced most young in spring and autumn.
