Rangeland FORESTER’S By Javed Iqbal PhD Scholar Department of Silviculture, Faculty of Forestry and Wood Sc, Czech University of Life Sciences, Prague •Rangelands are vast natural landscapes in the form of grasslands, shrublands, woodlands, wetlands, and deserts. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras. Rangelands do not include barren desert, farmland, closed canopy forests, or land covered by solid rock, concrete and/or glaciers. (http://en.wikipedia.org/wiki/Rangeland) •(n.) Land supporting indigenous vegetation that either is grazed or that has the potential to be grazed, and is managed as a natural ecosystem. Range includes grassland, grazable forestland, shrubland and pastureland. Range is not a use. (adj.) Modifies resources, products, activities, practices, and phenomena pertaining to rangeland. cf. rangeland, forested range, grazable woodland, shrubland, pastureland. (Society for Range Management. )
Definition of Range Management FORESTER’S By Javed Iqbal PhD Scholar Department of Silviculture, Faculty of Forestry and Wood Sc, Czech University of Life Sciences, Prague •Range management is the use of grazing land to ensure consistent livestock production and, at the same time, conserve range resources. (Glossary of Environment Statistics) •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. (Society for Range Management.) •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. (University of Idaho)

Not synonymous with animal month. Abbr. AUM. The term AUM is commonly used in three ways: (a) stocking rate, as in "X acres per AUM"; (b) forage allocations, as in "X AUMs in Allotment A"; (c) utilization, as in "X AUMs taken from Unit B." •Annual Plant Range on which the principal forage plants are self-perpetuating annual, herbaceous species. •Arid A term applied to regions or climates where lack of sufficient moisture severely limits growth and production of vegetation. The limits of precipitation vary considerably according to temperature conditions, with an upper annual limit for cool regions of 10 inches or less and for tropical regions as much as 15 to 20 inches. cf. semiarid •Basal Area The cross sectional area of the stem or stems of a plant or of all plants in a stand. Herbaceous and small woody plants are measured at or near the ground level; larger woody plants are measured at breast or other designated height.
Terminology in Range Management FORESTER’S By Javed Iqbal PhD Scholar Department of Silviculture, Faculty of Forestry and Wood Sc, Czech University of Life Sciences, Prague •Biennial A plant that lives for two years, producing vegetative growth the first year and usually blooming and fruiting in the second year and then dying. •Biomass The total amount of living plants and animals above and below ground in an area at a given time. •Browse (n.) The part of shrubs, woody vines and trees available for animal consumption. (v.)

In addition to site characteristics, it is a function of management goals and management intensity. (SRM) The amount of forage produced annually in a management unit is only one attribute used to determine carrying capacity. The forage also has to be available to the animals. On many rangelands, the carrying capacity may be less than forage production would indicate because parts of the management unit are inaccessible to grazing animals. In essence, forage is present but unavailable. •Climax (1) The final or stable biotic community in a successional series; it is self- perpetuating and in equilibrium with the physical habitat. •Closed Area Any area closed to certain types of use for management purposes. •Community A general term for an assemblage of plants and/or animals living together and interacting among themselves in a specific location; no particular successional status is implied. •Conservation The use and management of natural resources according to principles that assure their sustained economic and/or social benefits without impairment of environmental quality. •Consumers Heterotrophic organisms, chiefly animals, that ingest other organisms or particulate organic matter.

On many rangelands, the carrying capacity may be less than forage production would indicate because parts of the management unit are inaccessible to grazing animals. In essence, forage is present but unavailable. •Climax (1) The final or stable biotic community in a successional series; it is self- perpetuating and in equilibrium with the physical habitat. •Closed Area Any area closed to certain types of use for management purposes. •Community A general term for an assemblage of plants and/or animals living together and interacting among themselves in a specific location; no particular successional status is implied. •Conservation The use and management of natural resources according to principles that assure their sustained economic and/or social benefits without impairment of environmental quality. •Consumers Heterotrophic organisms, chiefly animals, that ingest other organisms or particulate organic matter.
