The grazing value and capacity of the land is a factor of certain attributes such as the soil condition, grass species composition, density, and abundance amongst others. These attributes are further influenced by rainfall activities and the intensity of utilization of the grazing materials. Grazing management refers to the approaches that farmers use to ensure that their livestock have controlled access to a grazing area. The grazing habits of these animals have varying degrees of impact on the grazing. For example, donkeys are heavy grazers, and sheep are selective grazers. Selective grazing is where the animal only selects to utilize certain grass species (e.g. Brachiaria nigropedata) that are more palatable or valuable than others. When heavy and selective grazing pressure on the most palatable species is continuous over a longer time, these grasses become locally extinct or depleted. This leaves the less valuable grass species (e.g. Aristida stipitata) to dominate that grazing area. These are the grasses that animals have at their disposal during the dry season because they were least utilized during the active growing period (summer months) and had a chance to grow to maturity. Due to their rigid structure for example, the animals struggle to eat/digest them, limiting the daily intake.
