Understanding space‐use patterns by elk (Cervus canadensis) is essential to alleviating human‐elk conflicts, particularly when crop depredation by elk can make it harder to justify to the public the need to restore elk populations to regions with agricultural landscapes. In 2016–2017, we used global positioning system data from 20 female elk to investigate their selection for agricultural cover during the agricultural season (1 May–31 Oct) in northwestern Minnesota, USA. We estimated resource selection functions with resource availability defined at the home range scale. Elk space use was primarily determined by distance to forest cover in areas proximate to agricultural fields. During diurnal periods, elk selected areas with forest cover near agricultural fields planted with legumes and cereal. During nocturnal periods, elk selected for agricultural fields with little to no canopy and that were planted with legumes. We suggest that management of elk in northwestern Minnesota will require practices that discourage the use of agriculture by elk while improving natural habitats within areas managed for elk restoration. We suggest that forestry practices (i.e., thinning and burning) could improve cover and forage openings for elk in restoration areas. Furthermore, managers could work with agricultural producers where elk occur to plant crops favored by elk (i.e., legumes) outside known home ranges and plant fields within home ranges with crops that elk avoided (i.e., hay). Collectively, these practices may shift the ranges of elk herds into restoration areas and lower conflict between the public and elk restoration efforts. © 2020 The Wildlife Society.

明尼苏达州农业季节女性麋鹿的栖息地选择

了解麋鹿(加拿大鹿)的空间使用方式)对于缓解人与麋鹿之间的冲突至关重要,特别是当麋鹿对作物的掠夺使公众更难证明有必要将麋鹿种群恢复到具有农业景观的地区时。在2016–2017年,我们使用了来自20名雌性麋鹿的全球定位系统数据,调查了他们在美国明尼苏达州西北部的农业季节(5月1日至10月31日)进行农业覆盖的选择。我们估计了资源选择功能,其中资源可用性在家庭范围范围内定义。麋鹿的空间利用主要取决于靠近农田的森林覆盖距离。在白天,麋鹿在种植豆类和谷物的农田附近选择了森林覆盖的地区。在夜间,麋鹿被选为几乎没有树冠且种植豆类的农田。我们建议,明尼苏达州西北部的麋鹿管理将要求采取一些措施,以阻止麋鹿使用农业,同时改善管理麋鹿恢复区域内的自然栖息地。我们建议林业实践(即间伐和焚烧)可以改善恢复区麋鹿的覆盖和觅食开口。此外,管理人员可以与发生麋鹿的农业生产者合作,种植已知家园以外的麋鹿(即豆类)所偏爱的作物,以及避免麋鹿的作物(即干草)在本家范围内的田地。总的来说,这些做法可能会将麋鹿群的范围转移到恢复地区,并减少公共和麋鹿恢复工作之间的冲突。©2020野生动物协会。我们建议,明尼苏达州西北部的麋鹿管理将要求采取一些措施,以阻止麋鹿使用农业,同时改善管理麋鹿恢复的地区的自然栖息地。我们建议林业实践(即间伐和焚烧)可以改善恢复区麋鹿的覆盖和觅食开口。此外,管理人员可以与发生麋鹿的农业生产者合作,种植已知家园以外的麋鹿(即豆类)所偏爱的作物,以及避免麋鹿的作物(即干草)在本家范围内的田地。总的来说,这些做法可能会将麋鹿群的范围转移到恢复地区,并减少公共和麋鹿恢复工作之间的冲突。©2020野生动物协会。我们建议,明尼苏达州西北部的麋鹿管理将要求采取一些措施,以阻止麋鹿使用农业,同时改善管理麋鹿恢复的地区的自然栖息地。我们建议林业实践(即间伐和焚烧)可以改善恢复区麋鹿的覆盖和觅食开口。此外,管理人员可以与发生麋鹿的农业生产者合作,种植已知家园以外的麋鹿(即豆类)所偏爱的作物,以及避免麋鹿的作物(即干草)在本家范围内的田地。总的来说,这些做法可以将麋鹿群的范围转移到恢复地区,并减少公共和麋鹿恢复工作之间的冲突。©2020野生动物协会。
