| Outline of Final Research Achievements |
The purpose of this study is to evaluate the value of Kayaba, (Kaya field), which is still used today, from multiple perspectives. The effects of the fire treatment, herbaceous and fungal fauna studies, and soil studies were conducted in a Kayaba, located in Otari village, in Nagano prefecture. The vegetation structure and its biomass differed greatly from place to place, and the differences in soil quality have led to differences in the vegetation. In addition, this study revealed that it has an impact on the quality of the thatch. It was also found that the presence or absence of burning has a significant impact on the quality of thatch and that special fungi exist on thatched roofs. This study highlights that the biota, quantity and quality of thatch production in the thatch field were strongly influenced by human management, such as burning and harvesting.

| Academic Significance and Societal Importance of the Research Achievements |
小谷村茅場での様々な分野の研究から、近年問題となっている茅の生産量の低下および茅の質の低下の現状把握とその原因の一端を明らかにすることが出来た。具体的には、刈り取りや火入れなど、茅場管理のための撹乱の影響が大き過ぎると、土壌表層浸食が促進されてしまい、茅の生産量および茅の質低下をもたらす可能性を明らかにした。これらを踏まえ、茅場および茅葺き民家の持続的利用を講じる必要がある。
