The study is a part in a more comprehensive series of investigations into the profitability of forest improvement measures. The present paper describes a new method for calculation of the suitability of various peatlands for forest drainage. According to this method, the net profit is calculated as the difference between the gross profit and the costs, and the profitability coefficient, as the ratio between the gross profit and the costs. The most important factors used for calculation of the gross profit and the costs are as follows: the site quality index, the volume of the tree stand capable of development at the time of draining, the temperature sum and the stumpage development at the time of draining, the temperature sum and the stumpage price. For use in the field, simplified auxliary tables have been worked out.
