Natural value of ecosystems and their economic valuation, case of the middle Pomerania lakes

Summary/Abstract: The purpose of this article is the identification of relationships between the natural and the economic value of ecosystem. The authors attempt to answer the question how the natural value of ecosystems affects its economic value. The object of the analysis is 16 lakes of Central Pomerania, Poland. They have been grouped into 4 classes, adequate for their natural value. The natural value of each of the lakes has been determined on the basis of specially adopted criteria. Economic valuation has been based on two methods: the travel costs method and willingness to pay (WTP). The results of the analysis indicate the relationships between the natural value and the economic valuation of ecosystems. Using the travel cost method of valuation, the relation between those values is directly proportional. The WTP method indicates that an average nature valued lakes obtain the highest economic value. Lakes with a high natural value are less valued in terms of their economic value.
