| Research Abstract |
Coppice woods (so-called satoyama) managed by a short rotation for fuel production have been thought to maintain a high biodiversity and to function as carbon sink, but no studies supporting these views have been available so far. Biodiversity status and carbon cycle in coppice woods under short rotation management were studied. Vegetation heterogeneity among small compartments of different ages enhanced a high biodiversity.
Carbon flux along increasing age of coppice woods was quantitatively evaluated, and the best tree age to harvest was determined based on the rate of biomass increase. These results are to be transferred to NPO's and administrative organs as useful guidelines for effective use of coppice woods.
