Abstract
The current concept of rangeland condition is faced with many problems that make it difficult for managers to apply. The concept is based on climax theory, which itself has been criticised by many scientists, as it also fails to reflect the real status of rangelands based on all the functions and benefits that they are able to provide. Considering the objectives of rangeland management, a new concept of rangeland condition based on ecological and economic criteria (ECEA) is suggested in this article. In this concept, rangeland condition is achieved as ‘the ratio of current benefits of a rangeland to the operation costs for its ecological restoration (to the extent that the most sustainable benefits provided). Furthermore, based on this new concept an equation is developed for quantitative measurement of the rangeland condition. We believe that this new concept can solve many problems around the existing concept of rangeland condition.
