Use prescribed burning on grasslands
A controlled trial in upland grassland at Highmoor State Forest, KwaZulu-Natal, South Africa (Mentis & Bigalke 1981), in 1973-1977 found that grey-winged Francolinus africanus and red-winged F. levaillantii francolins were found at higher densities in unburned, rather than burned areas immediately after fire, but that preferences were reversed in the year after burning. At the start of the experimental period (spring 1975), francolin densities were higher in an area sunject to large scale burns than an area under patch burning, but by autumn 1977 there were significantly higher densities in the patch-burned area.
