An experiment on the use of highintensity fires to control bush encroachment in South Africa's Kruger National Park (KNP) has revealed that these fires did not result in a meaningful long-term reversal of the problem.
In mid-February 2023, the results of this largescale, decade-long investigation were published in the Journal of Applied Ecology in an article titled 'High-intensity fires may have limited medium-term effectiveness for reversing woody plant encroachment in an African savanna'.
Prof Brian van Wilgen, emeritus professor of invasion biology at Stellenbosch University (SU) and one of the co-authors of the article, says most studies that advocate the use of high-intensity fires in the fight against bush encroachment are based
