Sažetak:
Within the framework of the European Union project CADSES "Carbon-Pro" and with the help of Croatian Forests Ltd. on 21 September 2007 a station for continuous monitoring of forest carbon and energy fluxes has been put into operation. The station is located within a lowland oak forest complex, in the Forest Mnagement Unit "Jastrebarski lugovi", forest compartment 37a. It is a 35-years old Pedunculate oak (Quercus robur L.) stand with significant share of other tree spcies (Black alder, Field ash, Hornbeam etc). Acquired data should enable us to better understand the processes, causes and effects that environmental factors have on Pedunculate oak stands and lowland forest in general. The station is first of such kind in Croatia and wider in South-European Region and as such has already become invaluable source of new data. At the station a wide range of meteorological and ecological variables is continuously measured and recorded. The fluxes of CO2, sensible and latent heat are estimated using eddy covariance method. In this work we present the preliminary results of the first year of our research. We illustrate changes with time of tatal precipitation (P), daily evapotranspiration (ET) of the stand and surface soil water content (SWC) during period January - August 2008. Comparison of aboveground biomass growth estimated with dendrometer bands and Net Ecosystem Productivity (NEP) measured with eddy covariance showed good correlation in the first half of the growing season. Negative NEE (i.e. CO2 assimilation) in summer still has to be explained in terms of biomass growth. High rate of soil respiration in summer could be an indicator of increased root respriration and root growth, but further research is necessary before conclusions could be made.
