The SavFIRE (Savanna Fire Ignition Research Experiment) burning trial was initiated in 2006 in the Kruger National Park in South Africa. The objective of the trial is to test the hypothesis that the resultant fire mosaic of controlled burns applied as point and perimeter ignitions, is significantly different when applied to small areas, but becomes increasingly similar as the burnt areas increase in size. In 2002 the official burning system in the Kruger National Park was changed and involved applying controlled burns as point ignitions rather than perimeter ignitions because it was believed that this would promote the biodiversity of the overall ecosystem because the fires would be more diverse in terms of type and intensity with resultant different effects on the flora and fauna in the burnt area. However, point ignitions are more difficult to control compared to perimeter ignitions which are applied to areas with prepared or natural firebreaks. If, however, the same diverse fire mosaic can be developed by applying perimeter ignitions to areas above a certain threshold size this would be an attractive ignition procedure for situations where the risk of wild and/or escaped fires is too great. During the 2006 and 2007 implementation of the SavFIRE project, point and perimeter ignitions were simultaneously applied to paired areas approximately 500, 1000, 2000 and 3000 hectares in size. Preliminary results indicated that a more diverse burning pattern developed as the size of burn increased but that weather conditions also played a critical role in the resultant pyrodiversity. The pyrodiversity data are currently being analysed in detail to test the hypothesis that the resultant fire mosaic of controlled burns applied as point and perimeter ignitions is significantly different when applied to small areas, but becomes increasingly similar as the areas being burnt increase in size.
