Résumé :
|
Results are presented from an ongoing research study of the productivity of forest trees in France. The results provided here are from studies on the height growth of beech [Fagus sylvatica] in northern France, and focus on the growth patterns that have been delineated (over the period 1870 to 2000), and the contrasts that have been found between the NE and NW regions. The study method adopted, and the growth model that has been derived, are described in detail. Different scenarios were simulated for the development of mature beech by the year 2100 in order to clarify the management options that are available; these consider age of exploitation, aspect and storm risk. The findings are discussed and conclusions drawn.
