Public preferences and willingness to pay for preservation of Mazandaran forests (Case study: Soleyman-tangeh (Sari))

Determining the real value of forest resources, due to their significant function and ecosystem services, has a great importance. This study tries to evaluate and estimate preservation value of forest resources in Soleyman-tangeh in Mazandaran province and analyzes parameters affecting individual public preferences in 2007. Willingness to pay (WTP) of individuals was specified, using contingent valuation method (CVM) and Logit regression model and also effective factors on WTP, were studied. Results showed that individual preservation WTP in Soleyman-tangeh forest had direct relation with income, education and the number of visits but negative relation with bid and age. Number of visits had the greatest elasticity and marginal effect. Therefore it could be considered as the most important factor for accepting proposed preservation amount. The calculation of the expectancy of WTP using Logit Model led to 7360.155 and 274613.2 Rials monthly WTP per person and annual family pay amount for preservation purposes, respectively.
