  Abstract:  The present paper presents a detailed analysis, on a long time period, 1972-2002, of the coppice that is in the responsibility of O.S. Baia Mare. The field activity proved that a cost-benefit analysis for the forest ecosystem from our country is difficult to be made, but an analysis of the productivity of the ecosystem is easier to be done and can also be presented briefly. These analyses can be used by teams of economists and ecologists in order to present the quality of the environmental factors, of the processes of degradation or amelioration for a specific area, and to suggest an environment protection strategy that is going to be developed on a long time period. For O.S. Baia Mare, the indirect economic value of the forest ecosystem is not presented in official documents. Through this paper we measure the value of the forest ecosystem, the nature and the intensity of the destabilization factors and we conclude that the diversity of the coppice has decreased, but the local species of forest have not disappeared, generating new phase of succession of the ecosystems.

Key words: pollution, forest ecosystems, intrinsic economic value
