Strategies for Sustainable Livestock Grazing: Ecological, Economic and Social Implications

Newswise — The growth of grasses on South Dakota rangeland provides forage for livestock, habitat for wildlife and a number of ecosystem services. For ranchers, grass growth affects the health and profitability of the cattle they graze as well as the value of their land.

An article in the March 2010 issue of Rangeland Ecology & Management contrasts the long-term production and profitability of rangelands in western South Dakota that were in varying range conditions, from excellent to good to low-fair. The study spans 34 years, from 1969 to 2002and addresses the economic parameters of annual total gross income, annual total expenses and annual net income per hectare (2.47 acres).

For conservationists and rangeland professionals, conventional wisdom has long held that grazing livestock on rangeland in good to excellent condition rather than in a lesser condition is the most productive, both ecologically and economically. Heavy grazing can lead to changes in the plant species present and a decline in range condition. Yet, ranchers generally maintain a lower level of range condition and neither profitability nor sustainability have been negatively affected.

Results from this 34 year record show that profit actually increased for the good and low-fair condition range through time , while it remained steady in excellent condition range. Range in low-fair condition supported a higher stocking rate indicating that ranchers are acting in a manner that is both sustainable and profitable over the long term.

However, this practice may not be the most beneficial to the environment and society at large, and incentives may be needed to take ranchers in a different direction. The authors note that “some ecosystem goods and services, increasingly demanded by society, come at a cost to the rancher. If ecosystem services generally associated with high range condition, such as wildlife habitat, floristic diversity, and improved hydrologic function, are publicly valued, and associated markets have not been established in the private sector, then funds cost-shared by federal, state, and private organizations must provide the incentive to direct ranchers’ decisions.”

About Rangeland Ecology & ManagementRangeland Ecology & Management is a peer-reviewed journal of the Society for Range Management that is published six times a year. The journal provides a forum for the presentation and discussion of research information, concepts, and philosophies pertaining to the function, management, and sustainable use of global rangeland resources.
