Ÿe term “rangeland” is rather nebulous, and there is no single de¤nition of rangeland that is universally accepted by land managers, scientists, or international bodies (Lund, 2007; Reeves and Mitchell, 2011). Dozens and possibly hundreds (Lund, 2007) of de¤nitions and ideologies exist because various stakeholders o¬en have unique objectives requiring di¦erent information. For the purpose of describing the role of remote sensing in a global context, it is, however, necessary to provide de¤nitions to orient the reader. Ÿe Food and Agricultural Organization (FAO) of the United Nations convened a conference in 2002 and again in 2013 to begin addressing the issue of harmonizing de¤nitions of forest-related activities. Based on this concept, here rangelands are considered lands usually dominated by nonforest vegetation. Ÿe Society for Range Management de¤nes rangelands as (SRM, 1998)

Land on which the indigenous vegetation (climax or natural potential) is predominantly grasses, grass-like plants, forbs, or shrubs and is managed as a natural ecosystem. If plants are introduced, they are managed similarly. Rangelands include natural grasslands, savannas, shrublands, many deserts, tundra, alpine communities, marshes, and wet meadows.
