The goal of the proposed project is to make an access of the Methodological and Experimental Research Centre and Infrastructure (MERCI) for community of EU researchers interested in the forest stand ecophysiology and impact of Global Climate Changes. The MERCI is constructed as a cluster of special tools used for the long-term research on the level of a forest stand. The capacity (up to 20%) of MERCI can be used for users from EU countries for their research. The users will be selected on the annual basis upon submitting project proposals evaluated by an Int. Sci. Committee. Because of the unique equipment of MERCI and a participation in EU R&TD programmes, international cooperation is expected.
