The results are summarized as follows:Nisihara, the western part of the Nasunohara upland in Tochigi Prefecture, is situated in the northeast part of the Kanto Plain. Nisihara, located in the center of the Nasu alluvial fan is composed of acid and volcanic ashes which are less productive. The farmers had used the lands as upland farming fields before 1960. The farmers needed to add to the soil a lot of organic fertilizers so as to keep them productive. Consequently the farmers took good care of the plain forests with the aim of collecting fallen leaves in winter and making them into manure. As well as fallen leaves, the plain forests have supplied the farmers with materials such as wood for fuel.Since the 1960s, the reclamation of the paddy fields has been in progress, and the way of farming has changed into the production of rice crops in paddy fields. Growing rice in the paddy fields, compared with the upland fields, depends less upon organic fertilizer. Consequently, the farmers stopped gathering fallen leaves, wood for fuel and other subsistence goods from the plain forests owing to the change of their way of life under the influence of the commercialized economy.The unused forests in the old village of Niwatoko have been sold to real estate agents or have been bought as the sites for public institutions. The remaining forests at Niwatoko are left uncared for and unused.The vast plain forests of broad-leaved trees in the Senbonmatsu area, which were bought by the enterprise Senbonmatsu Farm after World War II, were replaced by pine forests to create economic forestry.
