| Research Abstract |
In Shizuoka prefecture, farmers traditionally cover furrows in green-tea fields with grass(mainly Miscanthus sinensis and Pleioblastus chino). The semi natural grasslands from where this grass is collected are called Chagusaba. The results of analyses carried out by aerial photography and using GIS at Higashiyama area in Kakegawa city show that 65% of the area of a tea field is maintained as semi-natural grassland. This fact is interesting because, in Japan, the area covered by semi-natural grassland is decreasing, and some natural plants found in semi-natural grasslands are now endangered. In contrast, Chagusaba provide an important habitat for natural plant species of semi-natural grasslands. Chagusaba is considered as a good example of traditional Satoyama landscape and biodiversity conservation maintained by agricultural cultivation.
