Oswald s standard rules show a relatively narrow range of variation for young stands, and represent a rather mild type of silvicultural treatment. Two more vigorous types of silviculture are proposed and tested: _ Very early energetic cleanings leading to almost free growing of young stands; _ A "discontinuous" silviculture, with near-free growing not taking place until stand height reaches about 18m, after an extended phase of "squeezing/selection". The expected results from such silviculture, in terms of increment in diameter and height of pruning, are extrapolated from early measurements carried out in the tested stands and the output of other trials.
