The regional ecology of alternative states and thresholds:strategies for ecological site descriptions

摘要：

Introduction Land dynamics,ecosystem resilience,and the interaction of management decisions with them vary significantly across space.One-size-fits-all applications across distinct land types have been responsible for many failures in rangeland management.Ecological Site Descriptions ( ESDs) and similar land unit classification systems specify the characteristics of different land areas associated with variation in rangeland potential,ecological dynamics,vulnerabilities,and monitoring needs.
