The experiments were carried out in an even-aged teak (Tectona grandis Linn. f.) plantation located in the upper part of the Chao Phraya river basin, in Mae Mo district, Lampang Province, northern Thailand. Teak plantations have been widely established throughout the tropics, especially in Indochina and India, due to their high market value—a trend that is likely to continue in the foreseeable future. A case in point is Thailand, where significant decreases in forest area were documented until the 1980s. Forest rehabilitation and plantation have since been vigorously promoted, resulting in the establishment of large-scale teak plantations by the Forest Industry Organization, one of which is used here as a case study.The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system.
