In this paper, we conduct a cost-benefit analysis (CBA) of five alternative management strategies for red deer in Denmark: free harvest, trophy hunting, maximum harvest and two cases for natural demographic population compositions. To capture the outcome under each strategy we use a biological sex- and age-structured population model. The net benefit function includes meat values, recreational values, browsing damage costs and traffic damage costs and these values and costs are assumed to differ for the various sex and age classes of red deer. We show that the maximum harvest strategy leads to a reasonably high positive total net benefit, while the free harvest strategy yields a small positive net benefit. On the other hand, the trophy hunting strategy generates a high negative net benefit, while small negative net benefits are obtained under the two strategies for natural demographic population compositions.
本文针对丹麦五种不同的赤鹿管理策略进行了成本效益分析（CBA）：自由收获、奖杯狩猎、最大收获以及两种自然种群结构。为了捕捉每种策略下的结果，我们使用了一个具有生物性别和年龄结构的种群模型。净收益函数包括肉类价值、娱乐价值、啃食损害成本和交通损害成本，并且这些价值和成本因赤鹿的不同性别和年龄组而异。我们发现，最大收获策略会带来相当高的正总净收益，而自由收获策略则会带来较小的正净收益。另一方面，奖杯狩猎策略会产生高的负净收益，而在两种自然种群结构策略下则会得到较小的负净收益。
