Abstract: Considering the high value of pinewood forest in Tuscany for the reforestation of coastal sands it is extremely important to improve the knowledge on the ecology of these ecosystems, especially in these area where difficult environmental conditions joined with damages of the canopies (marine aerosol) could debilitate the trees, rendering them more vulnerable to damages caused by attack of fungus or insect. In our research we carried out long-term micrometeorological, gas exchanges at canopy and soil level using the eddy covariance method and sap fluxes measurements (1999-2007) in a coastal pine forest situated in the San Rossore Regional Park (Tuscany,Italy). The analysis of meteorological data showed a variation of rainfall regime with a decrease of precipitation during the spring; at the same time we observed a reduction of tree water use and stand level carbon assimilation during the summers. On the contrary the evapotranspiration (ET) of the stand, measured using the eddy covariance method, showed a different trend, presumably influenced by other components like see breeze (advection), etc.
