Gate Preventing Deer's Entrance

Because, in accordance with the increase of deer in Oku-nikko, their entrance into wetlands including the Senjogahara Marshland and destruction of wetland vegetation were concerned, fences to prevent their entrance were established in order to integrally preserve the environment of the Senjogahara Marshland and its surrounding forest vegetation. Even after the establishment, various efforts have been still made including the improvement of the fences.

Invasive Plants Extermination Efforts

In the Oku-nikko area, valuable indigenous plants, such as the Spiraea salicifolia and Fireweed , had been threatened by invasive plants including the Rudbeckia laciniata. Therefore, extermination projects were conducted from 1976 with the cooperation of volunteers, and these invasive species were drastically reduced. However, eradication has yet to be achieved, and the activity remains ongoing.
