摘要: Active adaptive management is increasingly advocated in natural resource and conservation biology. looks at the benefit of employing strategies that may be suboptimal near term but which provide additional information will facilitate better future years. However, when comparing policies it traditional to weigh rewards geometrically (at a constant discount rate) results far-distant making negligible contribution total benefit. Under such discounting scheme active rarely much benefit, especially if learning slow. A growing number authors advocate use alternative forms evaluating optimal for long-term decisions have social component. We consider theoretical harvested population recovery rate from an unharvestably small size unknown look effects on experimental three different are employed. geometric discounting, with 5% per annum, managing learn actively had little This study demonstrates functions more heavily result conservative harvesting strategies, do not necessarily encourage learning. Furthermore, strategy equivalent lower rate. If made mandatory calculating environ- mental then this affect structure regimes change how we willing invest
