We examined the influence of tree thinning on the abundance of mammals in a Japanese larch plantation in Mt Gariwang, Pyeongchang, South Korea. In 2014 and 2015, from April to October, we recorded the presence of tracks as a proxy for abundance, for the following seven mammalian species: Korean hare , raccoon dog , Siberian weasel , Eurasian badger , water deer , roe deer , and wild boar . We also assessed how the intensity of tree thinning affected vegetation cover; there were significant differences in number of standing trees, basal area, coverage of vegetation layers, and number and volume of downed trees among the control, moderately thinned, and intensively thinned stands. We found significant differences in the abundance of tracks among the stands for three mammal species. In four mammal species, the abundance of track was significantly correlated with volume of downed trees, coverage of ground vegetation, number of downed trees, and number of standing trees, according to stepwise analysis. The presence and abundance of mammals is linked to habitat variables and forest managers should consider how habitat modifications will affect wildlife.
我们研究了在韩国平昌加里旺山的日本落叶松人工林中进行树木间伐对哺乳动物数量的影响。在2014年和2015年的4月至10月期间，我们记录了以下七种哺乳动物的踪迹出现情况，以此作为数量的替代指标：朝鲜野兔、貉、黄鼬、欧亚獾、獐、狍和野猪。我们还评估了树木间伐强度如何影响植被覆盖度；在对照林分、中度间伐林分和强度间伐林分中，立木数量、断面积、植被层覆盖度以及倒木数量和体积存在显著差异。我们发现，三种哺乳动物在不同林分中的踪迹数量存在显著差异。根据逐步分析，在四种哺乳动物中，踪迹数量与倒木体积、地面植被覆盖度、倒木数量和立木数量显著相关。哺乳动物的存在和数量与栖息地变量有关，森林管理者应考虑栖息地改造将如何影响野生动物。
