Abstract

A survey of elephant impact at various distances from roads was conducted in June 1978 for Sclerocarya caffra (marula) tree populations in Acacia nigrescens Tropical Plains Thornveld in the Kruger National Park, Republic of South Africa. Data from scar recovery indicate that widespread scarring of S. caffra trees by elephant commenced in 1973, coinciding with a wet cli- matic phase. Elephant impact, old and fresh and irrespective of kind, decreased with distance from roads. Substantially higher impact was also recorded along S. caffra population boundaries. The most recent impact on some populations was higher than expected from the established relationship between elephant impact and tree density.
