Abstract
A large-scale fence which prevented the invasion of the deer on Senjogahara moor of Nikko National Park has seven opening points that were not able to get a fence ready. When many deer invade the inside of the fence from these opening points, the function of the fence is lost. This study clarified the enforcement process of the invasion countermeasures from 2006 in the opening point, and evaluated the effectiveness of countermeasures from the number of invasions of the deer. As a result, the net in the river, the grating and the supersonic wave device in the road were carried out, and those three kinds of countermeasures were effective. This result serves as a reference for other large-scale fence to prevent deer.
