Switching abruptly from on to another rotation period may cause either short- term gains to forest enterprise, or losses in cases of lengthening of the rotation period. Besides, there should toe taken inito account loss in usage otf capaoity of forest industries depending on raw materials delivered by forestry. Such losses may cause secondarv, terciar, etc. consequences throughout the whole economy.
