The population of barnacle geese wintering in Denmark has shown a steep increase during the last decades, prompting a parallel escalation of agricultural conflicts. In Denmark, economic compensation to farmers suffering goose damage to crops is not practiced, but despite that the barnacle goose is fully protected, landowners can obtain a permit to undertake so-called derogation shooting (lethal scaring) to reduce local damage to agricultural crops where other means of scaring have been insufficient. Here, we describe the development in numbers and derogation efforts of barnacle geese in Denmark in the period 2010/11 – 2018/19. We demonstrate that differences in the number of issued derogation permits across the country is primarily explained by differences in barnacle goose abundance, and secondarily, by prevalence of vulnerable crops and differences in crop productivity. Hence, derogation efforts are highest in areas with many geese, high proportions of crops vulnerable to goose grazing and high crop yields. Our analysis indicates that the level of conflict, and probably the economic impact of affected farmers, is proportional to the abundance of geese present locally. While the increasing derogation shooting may be a temporary solution to individual farmers, current unorganised practice might only redistribute geese locally and increase energy demands of the affected birds. Currently, there is a lack of alternative and undisturbed accommodation areas in the Danish agricultural landscape for the displacement of geese to achieve a satisfactory effect of derogation shooting.

Barnacle Goose Brata leucopsis 减损与丰度和脆弱作物相关的射击努力

在过去的几十年里,在丹麦越冬的藤壶鹅的数量急剧增加,引发了农业冲突的平行升级。在丹麦,对遭受鹅类作物损害的农民没有实行经济补偿,但尽管藤壶鹅得到充分保护,但土地所有者可以获得许可进行所谓的减损射击(致命恐吓),以减少当地农作物对农作物的损害。其他吓唬人的方法是不够的。在这里,我们描述了 2010/11 至 2018/19 年期间丹麦藤壶鹅的数量发展和减损努力。我们证明,全国范围内颁发的减损许可证数量的差异主要是由藤壶鹅数量的差异来解释的,其次,易受害作物的流行和作物生产力的差异。因此,在有许多鹅、易受鹅放牧影响的作物比例高和作物产量高的地区,减损力度最大。我们的分析表明,冲突的程度以及受影响农民的经济影响可能与当地存在的鹅的数量成正比。虽然越来越多的减损射击可能是个别农民的临时解决方案,但目前无组织的做法可能只会在当地重新分配鹅并增加受影响鸟类的能量需求。目前,丹麦农业景观中缺乏替代性的、不受干扰的住宿区,用于迁徙鹅以达到令人满意的减损射击效果。在有许多鹅、易受鹅放牧影响的作物比例高和作物产量高的地区,减损力度最大。我们的分析表明,冲突的程度以及受影响农民的经济影响可能与当地鹅的数量成正比。虽然越来越多的减损射击可能是个别农民的临时解决方案,但目前无组织的做法可能只会在当地重新分配鹅并增加受影响鸟类的能量需求。目前,丹麦农业景观中缺乏替代性的、不受干扰的住宿区,用于迁徙鹅以达到令人满意的减损射击效果。在有许多鹅、易受鹅放牧影响的作物比例高和作物产量高的地区,减损力度最大。我们的分析表明,冲突的程度以及受影响农民的经济影响可能与当地存在的鹅的数量成正比。虽然越来越多的减损射击可能是个别农民的临时解决方案,但目前无组织的做法可能只会在当地重新分配鹅并增加受影响鸟类的能量需求。目前,丹麦农业景观中缺乏替代性的、不受干扰的住宿区,用于迁徙鹅以达到令人满意的减损射击效果。受影响农民的经济影响可能与当地存在的鹅的数量成正比。虽然越来越多的减损射击可能是个别农民的临时解决方案,但目前无组织的做法可能只会在当地重新分配鹅并增加受影响鸟类的能量需求。目前,丹麦农业景观中缺乏替代性的、不受干扰的住宿区,用于迁徙鹅以达到令人满意的减损射击效果。受影响农民的经济影响可能与当地存在的鹅的数量成正比。虽然越来越多的减损射击可能是个别农民的临时解决方案,但目前无组织的做法可能只会在当地重新分配鹅并增加受影响鸟类的能量需求。目前,丹麦农业景观中缺乏替代性的、不受干扰的住宿区,用于迁徙鹅以达到令人满意的减损射击效果。
