The authors report the results of experimental investigations about forest growth, yield and quality of timber assortments, carried out in Turkey oak high forest stands, grown after shelterwood cuttings applied on a wide forest area. The results, obtained after about 20 years of testing, relate to two different intensity of thinning “from below”, compared with areas left to natural evolution. Moreover, some data are reported about the production of litter on a period immediately following the experimental fellings; finally, some comments are made on economic and financial results resulting from intermediate thinnings.
