This work compares the net revenues of maintaining grasslands versus shrublands as part of the habitat of the Cervus elaphus big game species in Mediterranean agroforestry ecosystems. For this purpose, data published by the Regional Government of Andalusia (SW Spain) were used to analyze revenues and expenditures under two scenarios: an optimistic one and a pessimistic one. Revenue is generated from both the value of game trophies and the sale of meat. In the grasslands option, expenditure is associated with the need to supply supplemental food since, unlike shrublands, Mediterranean grasslands do not produce forage crops during the summer months. To analyze the expenditure of supplemental feeding, monthly market prices for corn grain in the province of Cordoba (this province covers an area of almost 1.4 million hectares) were obtained for the period 2015–2019. Our results show that, in net revenues terms, substituting shrublands for grasslands is not always the best option under the conditions analyzed.

地中海生态系统中的草地与灌木地栖息地和游戏管理：Cervus elaphus 物种的应用

这项工作比较了作为地中海农林业生态系统中鹿大型猎物物种栖息地一部分的草地与灌木地的净收入。为此，安达卢西亚地区政府（西班牙西南部）发布的数据用于分析两种情景下的收入和支出：乐观情景和悲观情景。收入来自游戏奖杯的价值和肉类的销售。在草原选项中，支出与提供补充食物的需要有关，因为与灌木丛不同，地中海草原在夏季不生产饲料作物。为了分析补充饲料的支出，科尔多瓦省（该省占地面积近 1. 400 万公顷）在 2015-2019 年期间获得。我们的结果表明，就净收入而言，在所分析的条件下，用灌木丛代替草地并不总是最好的选择。
