“…Evidence, albeit largely circumstantial, indicates that in general sour grassveld in South Africa has degraded and the grazing value is thus well below its potential (e.g. Rethman & Kotze 1986;Aucamp & Danckwerts 1989;Barnes 1990). This represents a serious economic loss to the livestock industry and to the nation.…”

Critical evaluation of grazing management recommendations for sourveld revealed scientific, economic and practical deficiencies. These recommendations are seldom adopted. Recent scientific evidence has facilitated the adoption of certain principles in new practical, economically viable recommendations aimed at maintaining or improving the resource while facilitating good animal performance. These are based on the principles that defoliation, particularly by sheep, is detrimental to the vigour of the preferred species and that extended rests are necessary as compensation.Recommendations are aimed at optimal utilisation of veld burnt in spring after a full growing season rest. This is followed by compensatory rests every alternate year with sheep alone or use by cattle for one or two years, depending on sheepxattle ratios, followed by a full season rest. Rested veld utilised during the dormant season is an important feed source.

“…Species were classified into three palatability classes (highly palatable, intermediate and unpalatable) according to research findings and the experience of researchers (Barnes et al 1984;1985;Rethman & Kotze 1986). Using data from long-term grazing system trials, weightings were derived for each class, and, together with species abundances, were used to calculate a range condition index (the so-called weighted palatability composition) which, in turn, was related to grazing capacity.…”
