由入侵的梅花鹿(Cervus Nippon Temminck)取食会对自然植被造成严重破坏，特别是在森林地面上。尽管有几项研究考察了梅花鹿的影响，但很少有人关注梅花鹿入侵的早期阶段。在这里，我们研究了梅花鹿饲养对日本神奈川箱根森林地面的影响，那里正处于鹿入侵的早期阶段。从2010年到2014年，我们建立了五个鹿围围栏，并监测了围栏内外植被的差异。我们发现，在一些地点，围栏内外的植被存在明显的差异，但在其他地点则没有。因此，我们的方法在检测梅花鹿觅食的早期效果方面是部分有效的。在入侵的早期阶段开始管理工作是将对自然植被的损害降至最低的具有成本效益的战略。我们的方法将有助于在梅花鹿入侵的早期阶段检测植被损害并建立管理计划。
Feeding by invasive Sika deer (Cervus nippon Temminck) causes severe damage to natural vegetation, especially on the forest floor. Although several studies have examined the effects of Sika deer, few have focussed on the early stages of deer invasion. Here, we examine the effects of Sika deer feeding on forest floors in Hakone, Kanagawa, Japan, which are in the early stages of deer invasion. We established five deer exclosure fences and monitored differences in vegetation inside and outside the fences from 2010 to 2014. We found clear differences between vegetation inside and outside the exclosures at some sites, but not at others. Thus, our approach was partially effective at detecting the early effects of feeding by Sika deer. Commencing management efforts in the early stages of invasion is a cost-effective strategy for minimizing damage to natural vegetation. Our approach will aid in detecting vegetation damage and establishing a management plan in the early stages of Sika deer invasion.
