Vegetation Benefits

Patch burning through preferential grazing of burned patches promotes a diversity of plant species (Figure 4). An abundance of forbs (broadleaf herbaceous plants) can be expected to increase following the fire and heavy grazing pressure of focal grazing for several years following burning. Forbs contribute an important element to wildlife habitat, as well as benefits to livestock. Given time to recover from focal grazing, the forb community changes (Figure 4).

Increases in some invasive plant species can be constrained by either intense grazing or growing season burns. This has been demonstrated in research with sericea lespedeza (Lespedeza cuneata) in tallgrass prairie (see invasive plants section).

Figure 4. Plant diversity, total plant cover, tallgrass cover, and forb cover is greater for PB than the traditional management practice of grazing and burning the entire pasture.
