Supplementary feeding is a widespread but controversial practice in game management. While many studies have been conducted on this issue, there is limited empirical evidence on how feeding affects damage caused by wildlife. In this context, the present study focused on the effect of artificial winter feeding on tree damage in three mountain regions in Poland.
The presence of additional winter food did not increase tree damage caused by deer in any region, as expected. Moreover, we observed that additional feeding mitigated forest damage in one region, where the highest level of deer impact had occurred. However, in this mountain region, the most important factor was elevation, which was used to classify additional feeding practice as efficient or inefficient. In the two other study regions, we did not observe any effect of supplementary feeding.
Additional winter supplementary feeding can reduce damage caused by deer in forest stands, but only in areas with high deer pressure. Moreover, feeders should be situated in locations > 600 m above sea level in our study area. © 2018 Society of Chemical Industry.
补充喂养是一种广泛存在但颇具争议的猎物管理方式。尽管针对这一问题已开展了多项研究，但关于喂养如何影响野生动物造成的损害的实证证据有限。在这种情况下，本研究集中探讨了人工冬季喂养对波兰三个山区树木损害的影响。
正如预期的那样，额外的冬季食物的存在并没有增加任何地区鹿造成的树木损害。此外，我们观察到，在一个地区，额外的喂养减轻了森林损害，而该地区发生了最高水平的鹿的影响。然而，在这个山区，最重要的因素是海拔，我们用它来对补充喂养实践进行有效的或无效的分类。在另外两个研究区域，我们没有观察到补充喂养有任何效果。
额外的冬季补充喂养可以减少森林中鹿造成的损害，但仅在鹿压力高的地区。此外，在我们的研究区域，饲养器应位于海拔 > 600m 以上的位置。 © 2018 英国化学学会。
