This article estimates benefits from preserving wildlife resources. Contingent valuation method of dichotomous choice form was applied to the nightheron resource of Mt. Eourdeung in Gwangju, Korea. Author used Krinsky-Robb procedure to construct confidence intervals around benefit estimates derived from the logit models to determine whether there is a significant difference in willingness to pay estimates. While consumers’ sociodemographic characteristics except for income were not important determinants of the WTP for preserving the nightheron, the WTP itself was found significantly affected by respondents’ value system, environmental and economic concerns, and knowledge on the wildlife. Total preservation value of the nightheron is an estimated 9.6 billion Won, averaging about 23,500 Won per household.
