Thresholds for conservation and management: structured decision making as a conceptual framework

摘要: A conceptual framework is provided for considering the threshold concept in natural resource management and conservation. We define three kinds of thresholds relevant to Ecological are values system state variables at which small changes bring about substantial or specified dynamics. They frequently incorporated into ecological models used project responses actions. Utility components objectives performance yield value outcome. Decision prompt actions order reach objectives. derived from other decision process. advocate a structured making (SDM) approach within following identified: (possibly including utility thresholds), potential actions, monitoring program, solution algorithm (which produces thresholds). Adaptive (ARM) described as special case SDM developed recurrent problems that characterized by uncertainty. believe SDM, general, ARM, particular, provide good approaches conservation management. Use ARM also clarifies distinct roles thresholds, informed processes.
