エゾシカの交通事故対策に関する実験的研究

抄録

As measures to prevent collision of wildlife such as Ezo deer with vehicles, deer exclusion fences are effective, physically intercepting deer's crossing roads. However, Ezo deer are likely to enter roads from the ends of deer exclusion fences or footpaths of fields. Countermeasures against Ezo deer's entering roads are a One Way Gate and a Deer Guard (Texas Gate). The One Way Gate is a facility to make deer escape from roads. The Dear Guard (Texas Gate) prevents deer from entering roads from footpaths. This study investigated whether these facilities would actually effectively work on Ezo deer, conducting a field experiment by using part of a Ezo deer catching facility located in Makoi District, Shari-Cho, on Shiretoko Peninsula, Hokkaido, Japan.
The experiment results found: installing the One Way Gate at a part of the deer exclusion fence where shaped into a short V-lead instead installing it in line with the fence enabled panicking deer to more easily find the gate to escape; and the Deer Guard (Texas Gate) longer than 3m, significantly decreased the number of deer intruding on roads.
