The preservation of biodiversity is one of the most important matters in environmental economics. But, in general, the relevant trade-offs associated with the preservation option are not well known. The absence of a framework capable of relating theoretical and operational aspects is a restriction for understanding the subject of biodiversity. If we cannot measure it, there is no way to take rational actions to get preservation because each one (preservation and non preservation) brings expected gains and current losses of welfare for the society. The aim of this paper is to present a methodology that gives a value to the price for the preservation of biodiversity, by the adaptation of the approach developed by Montgomery et alii (1999). Summing up, this study tries to find the confidence interval for the value of willingness to pay for lump sum tax paid by society to take the preservation program for some endangered species. The viability or probability that the species remain alive in the future, the degree of genetic diversity and the use value are the elements, among others, involved in this process.
