In Ozegahara, the mire disturbance caused by feeding and digging of Menyanthes trifoliata by Japanese deer (Cervus nippon) feeding and digging up rhizomes has been increasing year by year since 1995. In this report, chronological changes of mire disturbance by deer and resulted mire evolution at Nakatashiro-Rugyu are discussed based on the time series photographic records of the deer disturbance of mire vegetation at this area. In the early stage of deer the disturbance of M. trifoliata, the disturbed area was confined within local locations with limited due to obstructions. In recent years, disturbed areas have been enlarged to the vicinity of wooden roads and to the central part of Ozegahara without hiding place for deer. As food, deer highly prefer M. trifoliata, one of the most valuable vegetation at Ozegahara. Considering the patterns of mire disturbance by deer as well as their inhabitance behavior at Ozegahara, discussion was made on the necessity of long term extensive studies on the recovery of vegetation from the mire disturbance caused by both digging and feeding of its rhizome by deer.
