The symposium was co-organized by IEFC European Institute of Cultivated Forests INRA National Institute of Agronomic Research and ENITAB National School of Agricultural Engineers of Bordeaux . There were seven plenary sessions and the papers published in this issue were presented in three sessions. - The article on potential for increase in CO2 flux from forest soils in Japan Ishizuka et al. was presented in session 1 on Carbon and Greenhouse Gases. This session provided an update and deep insights into the issues of C sinks and fluxes from forest soils. As illustrated by this article main items of interest in this session included the spatial and temporal changes due to high variability at the local and regional scales and the need to combine information from soil surveys with forest management in the context of the whole system soil-climate-forest practices . New attempts of modelling C fluxes were presented taking into account abiotic temperature and moisture and biotic vegetation species factors. Research results on C pools in forest ecosystems and their spatial and temporal variation were provided including dynamics of C in biomass components and in the forest soil. Development of methodologies for soil respiration and soil CO2 concentrations measurements were also presented. - The article on diversity of wood decomposer communities in different forest stands Kulhankova et al. was presented in session 2 on Soil .
