Carbon Absorption by Temperate Forest Ecosystems: Problems and Responses to a Changing Environmentill need to be solved in order to fully understand mitigation potentials of temperate forests and to answer to questions about their optimal management strategies. In this paper, results of recent researches conducted on global change and temperate forests will be provided.
