Yamashiro forest hydrology research site is located in the southern part of Kyoto prefecture. The site is in a deciduous broadleaf forest on weathered granite and the forest is also one of headstreams of Kizu River. The region used to be a bare area caused by the management as a suburban forest, until the re-vegetation was conducted by Johannis de Rijke about 100 years ago. After the invation by pine wilt disease in 1980’s. Quercus serrata (Konara ork) has taken over and the forest is now recovered. Such secondary forests are widely distributed throughout Kyoto-Osaka-Kobe and Seto Inland Sea coast area. Yanashiro research site was established to study internal mechanism of carbon circulation and to develop the flux observation method in such ecosystem. This site can be characterized by twin towers (one on the ridge and the other in the valley) to evaluate spatial variation characteristics on complex terrain.
