b) The experiences after hurricane Lothar in the state of  Baden-Württemberg (planning alternatives on windthrow areas, consequences, evaluation)
(LFV Baden-Württemberg RP Freiburg)

3. Stand care/tree harvest incl. wood fuel production / Windthrow timber processing

3.1 Harvesting, processing and hauling wood in well-structured stands in  accessible terrains with special emphasis on sort diversity, protection of the stand, young trees and soil as well as cost balance.
