Use of dogs to reduce crop damage by wild animals in Tokyo

摘要

There is over 20 billion a year in the amount of crop damage by wildlife in Japan. The amount of wildlife damage in Tokyo is only 0.2% of all over Japan, but understo-ry vegetation has been devastated through the predation of deer and that causes large scale soil erosion, agricultural and forestry damage in Okutama region.The present studies revealed that use of dogs, which was introduced in Nagano prefecture for the first time in 2007, has been effective to reduce crop damage in many parts of Japan. It is supposed that this measure may be effective in Okutama region. This paper tried to verify that the monkey dog is effective to wildlife damage control in this region.
