Basic components of values of biodiversity have been analyzed. The methods of estimation of various benefits of biodiversity conservation have been exposed with an emphasis on the contingent valuation methods. On the basis of the questionnaire prepared by the author various Willingness-To-Pay (WTP) values have been estimated for the non-use value benefits. Various estimations of the basic components of the value of biodiversity have been commented based on case study of the Bulgarian Danube islands. The results demonstrate relatively high WTP in favor of restoration of natural forests on the Danube islands, which is expected to promote the development of tourism and recreation, commercial and non-commercial fishing and hunting. It is expected that the growth of revenues from activities stimulated by biodiversity conservation as tourism, recreation, etc. will compensate the reduction of revenues from the reduced felling of timber from the poplar plantations.
