FORUM: Defining Goals and Criteria for Ecosystem-Based Management.

/ Identifying goals or targets for landscape and ecosystem management is now a widely recognized need that has received little systematic attention. At a micro-level most planners and managers of both ecosystems and economies continue to pursue traditional goals and targets that miss many desirable characteristics of ecosystem-based management goals. Desirable characteristics of ecosystem and landscape management goals and targets include: addressing complexity, transdisciplinarity, and the dynamic nature of natural systems; reflecting the wide range of interests and goals that exist; recognizing goals and values and limits; involving people and being explainable and implementable in a consistent way to different people and groups; and evolving adaptively as conditions and knowledge change. Substantive and procedural goals can be distinguished; the latter supporting the former. Substantive goals can be grouped according to their relationship to system structure, organization, and process/dynamics, and their disciplinary or subsystemic breadth. These discussions are illustrated by a review of the goals of biodiversity, sustainability, ecological health, and integrity. An example of a hierarchical framework of procedural goals and objectives that supports achievement of substantive goals is also provided. The conclusion is that a parallel, linked system of substantive and procedural goals at different levels of complexity and disciplinarity is needed to facilitate ecosystem-based management.KEY WORDS: Ecosystem management; Goals and objectives; Assessment criteria
