Mechanism
Heavy continuous grazing and drought will transition this site into a Shrubland State (2). The site is characterized by greater than 20 percent woody canopy cover.
Mechanism
Land managers may wish to use this site as pasture, or less commonly cropland. If woody species are present, brush management is necessary to remove trees and shrubs. Seedbed preparation and pasture planting are the final steps needed.
Mechanism
Prescribed grazing and brush management are required to restore the community back to a Grassland State (1). Removal of woody species below 20 percent allows more light and nutrients to herbaceous species. Reducing grazing pressure will allow plants to regain vigor and re-establish.
Mechanism
Land managers may wish to use this site as pasture, or less commonly cropland. Brush management, followed by seedbed preparation and pasture planting are needed to create a successful pasture.
