Five encroaching species (Acacia melifera, Acacia nolitica, Dichrostachys cinerea, Terminilia prunioides and Terminilia sericea) have been fire-girdled at various heights and during various seasons. The height of coppice has been measured at two assessments after fire-girdling and the number of dead plants noted. The regrowth was the lowest and mortality rate the highest for trees fire-girdled during the rainy season, i.e. between January and April. Fire-girdling is also most effective if done as near to groundlevel as possible. A minimum duration and intensity of the fire must be achieved, for fire-girdling to be effective. Post fire-girdling treatments, especially with browsers, is suggested, as coppicing does occur
