This report describes the Nature Game Instructors training course executed in a college curriculum and an extension lecture of Nara Saho College in December, 2003. The training course was carried out in the college campus and the forest of Gokoku shrine near the college for 3 days (9:00-18:00). The college students and the participants from the outside actively and enthusiastically enjoyed "Nature Game" as "Sharing Nature" activities set. The participants could improve their senses to the nature through Nature Game. This field activity program suggests to be effective in order to greatly change the approach of the students to the nature.研究報告

This study investigated current-year tree seedlings in a warm-temperate evergreen forest on Mt. Kasugayama, a World Heritage Site in Nara Japan. In 24 study plots (total area = 980 m^2) there were 1681 current-year tree seedlings, of 42 species. Symplocos prunifolia, Abies firma, Castanopsis cuspidata, Eurya japonica, Parthenocissus tricuspidata, Ampelopsis leeoides, and Rhus tricocarpa were abundant in the study pots ; dufing May and November of 2002, current-year tree seedlings of 55 species were found in a 45ha area. Mega- and mesophanerophytes (MM) and mesopharerophytes (M) represented 49.9% and 45.3%, respectively, of the life-form spectra of current-year tree seedlings, while nanophanerophytes (N) had a low value of only 4.8%. Of the 55 species that produced current-year seedlings, 9.1% were non-native.論文
