ABSTRACT
Rangeland Management includes techniques that are used to directly modify the species composition and/or structure of the vegetation. Many woody plants are undesirable because they are strong competitors that reduce the growth and production of understory vegetation. However, the understory vegetation appears to be tolerant to low density shrubs and herbage growth may be enhanced below certain woody-plant densities. Desirable forage species for livestock and game, and other desirable species for human recreation, have been encouraged on many thousands of hectares of formerly unproductive rangelands. Whatever the type of vegetational manipulation, increasing care for the needs of all objectives must be taken in its application. A major problem of manipulating vegetation is in the biology of all the species. Increasing human population reduces available acreage for grazing, recreational services, clean air, and production of clean water. Because land becomes scarce when demands increase, range-vegetation management must be practiced with increasing intensity.
