Nutrient hotspots from patch burning in a Namibian rangeland

摘要：

Although fires have shaped savanna rangelands for millennia, most farmers have controlled lightning induced fires on their farms for past decades, with resultant change in rangeland condition.A few farmers have tried to apply prescribed burning to portions of their farms, mainly to try controlling bushes that have thickened on the land, but very few apply patch burning for biodiversity, such as promoted by Fuhlendorf & Engle (2001).The significance of nutrient hotspots to savanna dynamics has been pointed out by Scholes & Walker (1993).This study, falling under the Biodiversity Transect Analysis in Africa (BIOTA) program, learns from a farmer who applies patch burning.
