Abstract

Wild boar Sus scrofa populations are actively expanding northwards. Their presence in the North is closely tied to anthropogenic activities, as wild boars are either fed, or find food and suitable habitat at farmlands. However, the nature reserves of the northern part of Russia show that wild boars are able to survive on their own even in a completely natural environment. In the taiga zone, there are habitats providing for their survival in winter: wetlands in mires and around large water bodies, and dense spruce forests. Continued northwards expansion of wild boar range is likely if pressure from hunting is reduced. Modelling based on climatic variables also shows that they could potentially inhabit vast areas in the North. The existence of wild boars in the North is interrelated with other species of relatively large mammals (beavers and roe deer) and partly supports the idea of “Pleistocene rewilding” in a boreal environment, i.e., the potential to increase the variety and numbers of megafauna representatives.

北方野猪(Sus scrofa)稳定生存的自然栖息地
野猪的数量正在积极向北扩展。野猪在北方的出现与人类活动密切相关,因为野猪要么在农田里得到喂养,要么在农田里找到食物和合适的栖息地。不过,俄罗斯北部的自然保护区表明,即使在完全自然的环境中,野猪也能独立生存。在针叶林区,有为野猪提供冬季生存条件的栖息地:沼泽和大型水体周围的湿地,以及茂密的云杉林。如果减少狩猎压力,野猪的活动范围有可能继续向北扩展。根据气候变量建立的模型也显示,野猪有可能栖息在北方的广大地区。北方野猪的存在与其他相对大型的哺乳动物物种(河狸和狍子)相互关联,并部分支持了北方环境中的 "更新世野化 "理念,即增加巨型动物代表的种类和数量的潜力。
