Environment creating and general social cost−consuming factors are of the utmost importance to realize the multifunctional forest management. As a result, in some forest districts, one notes a disproportionate relationship between the costs and incomes. It can determine the level of the achieved profitability and influence the availability of the financial resources. One of the crucial elements of the realization of the forest management is the constant control of the cash flow (income and costs). Because of the specification of the forest management, the flows are determined by the economic as well as ecological factors. This is the reason of exploring of the influence of forest habitat types on the sales income reached as part of the early and late thinning for positive selection. The income from the sales of 100,798 m3 woody raw material acquired from 3,628 ha was analyzed. Forest habitat type significantly influenced the income taken from the sale of woody raw material that was reached as the part of analyzed tending (V=44%). It was proved that forest habitat type in case of early thinning for positive selection had higher all−important influence on the income acquired from the sale of wood than in case of late thinning for positive selection, which was determined as the middle influence (V=56 and 24%, respectively).
