Abstract

Using field survey data and interviews with forest owners, managers, and neighbors conducted in Hachioji and Hino, southwest of Tokyo, Japan, we analyzed the relationship between management methods and community structure in secondary Quercus serrata-Q. acutissima woodland. Our survey identified four management types according to past and present uses and the management history of the woodland: traditional management, non-traditional management, ad hoc management, and no management. Management of the forest floor, such as mowing and litter gathering, had significant effects on many attributes of the vegetation structure of the woodland. The species richness of summer-green perennials was low where management practices were interrupted for a long period. Under traditional management, there was little variation in species richness between stands, while non-traditional management resulted in greater variation. To conserve the species richness of existing woodland by non-traditional management, it is necessary to manage the woodland continuously without long periods of neglect.
