The dominant species is red pine and there are also mixed evergreen and deciduous broadlef trees such as holly and azalea. Because of its high altitude (1000m), the climate is relatively cold for its latitude and snowdepth reaches up to 0.5m in winter. Soil is poorly developed due to underneath volcanic lava, land surafce is covered with a very thin layer of liter and its decomposing materials. We are measureing CO2 and energy balance in this red pine forest.The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system."],
