The results for one stand of Pinus sylvestris L. in the north of Spain have been evaluated in physical terms total volume veneer volume as well as in financial terms Land Expectation Value LEV showing some of the alternatives its feasibility in comparison with traditional management. silviculture green tree retention Pinus sylvestris L.
