Modern Art Range: Management of the Range.—The objective range management is the maximum produc-of meat and wool without damage to the 1. Overly optimistic estimates of the grazing icity of ranges have often resulted in over grazing and deterioration of vegetation. Where misuse has been continued to the point of de-vegetation, soil erosion and devastation of the land have resulted. The modern art range range manager's chief duty is to avoid such deterioration.Optical Range Finders. Optical range finders determine range by solving a right triangle in which one side and two angles are known, range being one of the unknown sides. Referring to Fig. 4, the range from a range finder PS to a target T is R. The distance between P and S is the range finder base length B. As the base length is increased, by enlarging the range finder, it becomes possible to obtain accurate readings at greater ranges. The lines of sight from P and rections such as atmospheric temperature, winds, and other factors.
A knowledge of botany and animal husbandry does not make a range manager, however, for range management is a science in its own right. As of 1963, 16 American universities gave degrees in range management, and the United States Civil Service Commission offered an examination entitled "Range Conservationist" for those desiring government employment in the profession. The American Society of Range Management, an international professional organization, publishes the Journal of Range Management, a bimonthly periodical devoted to range science. The Range Education Council is an organization of Western universities that studies range teaching programs and standardizes curricula in range management. |
