Overview

Range management is a distinct discipline founded on ecological principles and dealing with the use of

 rangelands and range resources for a variety of purposes

these purposes include use as watersheds ,wildlife habitat ,grazing by livestock ,recreation ,and aesthetics ,as well as other associated uses.

Inventory

Developing a plan for using rangeland resources requires information about the productive capability of the rangelands ,current condition , intended use , and land owner ives. Assistance with inventorying resources is available through local conservation districts and natural resource conservation service offices.

Practices

When developing a plan the rangeland resources , first consideration must be given to management of the vegetation resource through the use of a prescribed grazing system.

The preon should take into account periods of grazing , deferment ,rest , animal impact , and levels of use that will bring about desired changes in the plant community.

The second consideration in developing a plan is identifying those practices necessary to implement the desired prescribed grazing system. These practices help control or influence the movement of livestock necessary for uniform distribution of grazing. These practices may include water developments , fencing ,salting, stock trails ,and herding.

 When the vegetation management resulting from the prescribed grazing does not achieve the desired changes in the plant community within a reasonable length of time , one or more supplementary practices may need to be planned and applied to help accelerate the desired change . these practices often result in dramatic changes in the plant community and should be carefully planned and applied , with special follow_up management to insure they are effective and achieve the desired change .

Some of the practices to consider are seeding , brush management , prescribed burning , fertilizing , mechanical treatment , and water spreading.

There are areas that may require special consideration in developing management plans. This may include areas of sensitive soils , unique plants , riparian areas , adjacent land uses , recreation and historical sites.
