Restoration technologies to improve the grazing capacity of degraded arid-and semi-arid rangelands in South Africa
Introduction About 80％ of the total land area of South Africa is regarded as rangelands of which most are arid-or semi-arid.It is estimated that approximately 66％ of the rangelands are moderately to severely degraded ( Snyman,1988) and many have passed the thresholds of self recovery.Once irreversible transitions have occurred,restoration practices have to be implemented to assist the recovery of these degraded ecosystems (SER,2002).In most cases,the general aims of restoration is to increase the biodiversity for higher resilience,increase the vegetation cover to combat erosion and to improve the production potential for a higher grazing capacity (Bakker,et al.1996 ; Van den Berg & Kellner,2005 ).
