Theme 22: Grazing Management
Description
This study was conducted in the Pantanal of Mato Grosso do Sul state, Brazil, from September 1995 to July 1997. The objective was to evaluate the effect of annual burning on grasses and forbs biomass and standing dead in an ungrazed grassland of Elyonurus muticus. In two areas, one free of burning (control) and another area with annual burning, grasses, forbs aboveground biomass, and standing dead were collected. The experimental design was completely randomized with 10 replications. Burning modified the grasses and forbs biomass dynamics when compared to the area free of burning. After the first burning the grasses biomass reduced in, approximately, 22% and the forbs increased in 32%. After the second burning the grasses biomass reduced in, approximately, 35%, while the forbs was similar in both areas. The standing dead in the burning area was practically absent.
