JapanFlux2024 JP-Yms Yamashiro forest meteorology research site

Yamashiro forest hydrology research site is located in the southern part of Kyoto prefecture. The site is in a broadleaf forest which is built up on weathered granite and the forest is also one of headstreams of Kizu River. The region used to be cleared off as it was managed as a suburban forest, until a century ago, when the green development operated by Johannis de Rijke has brought vegetation restoration. After the invasion by pine wilt disease in 1980's, Konara oak has taken over and the forest is now regenerated.Yamashiro 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 observe space variation in complex terrain. Our research activity covers wide range of areas which include long term continuous observation of seasonal change using automated chambers and REA observation of trace gas flux as well as common ecological investigations. The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system.
