The geography of Fukuroi City, Shizuoka Prefecture, is characterized by hills of Satoyama Woodland, which consists of the Quaternary marine sediments. The geological outcrops in the hills are important not only for field study in school education, but also for extension of natural history for citizens. In order to effectively utilize the outcrops as educational materials, this study surveyed public perceptions of the natural history of the Satoyama Woodland in Fukuroi City. The questionnaire-sheet survey, composed of five geology questions (age, rock solidification, environmental fluctuation, and formation processes of hill features) and one ecology question (habitat of fireflies), was conducted on fifth and sixth graders of primary school students as well as adults of local residents. The survey results show that percentages of correct answers for the geological questions are lower by over 10% than for the ecology question. Cross tabulation made for the children population suggests the following four trends. First, the image of rock solidification is not clearly linked to those of geological age and hill geography formation. Second, we could not recognize linkage between geological age and images of events, which may occur during the time span. Third, there is little change in image of climatic warming degree, nevertheless they can image sea-level rising caused by climatic warming. Fourth, incorrect images on the geology can mislead to wrong schema for ecosystem conservation. On the basis of the survey results, five devices are proposed for more effective study plan on natural history of Satoyama Woodland: 1) reflection of feel of rocks, such as solidification, in discussion on geological processes and geographical features, 2) arrangement of geological and historical events in various time-scale, 3) story plotting about formation process of local nature in relating with global earth-history, 4) introduction of quantitative expression for environmental fluctuation, and 5) reconsideration on relation between geological processes and ecosystem conditions.
