放鳥直後期におけるトキ放鳥への住民意識: 佐渡市全域のアンケート調査から

摘要

To evaluate people's opinions concerning the release of the Japanese Crested Ibis Nipponia nippon, a questionnaire was mailed throughout Sado City, Niigata Prefecture, Japan. The 1, 000 target individuals were selected randomly from within the 20 to 79 year age group. Results from the 591 respondents indicated almost 74% to have appreciated the release, and only 26% have neither agreed nor disagreed. The most common reason people gave for their appreciation was "they have lived here", though only 16% of the people had actually seen the Japanese Crested Ibis in the wild. Their concerns related to the release were related mainly toward the success of the release father than to any harm the birds might cause to crops. Especially, they worried about the released Japanese Crested Ibis survival. These results may be affected by the media like TV. Many people treated Japanese Crested Ibis as a local symbol, or a symbol of nature, and only a few viewed the bird as a potentially commercial venurte. Similar results were obtained from a questionnaire on the Oriental Storks Ciconia boyciana in Toyooka City. The releases in the past have been done far from the villages. This Japanese Crested Ibis release is the second case done near the villages, just after the release of the Oriental Storks. The sequential research will be done to compare the two questionnaires relating to the Oriental Stork and the Japanese Crested Ibis.%2008年9月25日に新潟県佐渡市において，10羽のトキNipponia nipponが放鳥され，野生復rn帰が開始された。トキは，江戸時代（ここでは1730年代）の時点では，東北日本を中心に各rn地で生息していたことが安田健の調査から明らかになっている（安田1987）。明治時代に入rnり，乱獲の影響で急激に数が減少し，大正時代には絶滅したと思われていた。
