ABSTRACT
The lake ecosystem in the municipality of Saguiaran serves as a habitat for various flora and fauna species and a main source of water supply for agriculture and livestock production in the surrounding communities. The lake experiences periodic drying and its surrounding ecosystem has been significantly influenced by various anthropogenic activities and the introduction of alien species. Thus, this study assessed the lake diversity and the residents' willingness to pay for the protection. This study used the belt transect method to assess the diversity and contingent valuation to determine the willingness to pay for the protection. Results show that diversity (H' = 1.324) and evenness (J = 0.533) are low. Carabao grass (Paspalum conjugatum P.J. Bergius) is with the most abundant species that accounts for about 62% (n = 457) of the total plant individuals assessed. There are four statistically significant variables in correlation analysis and there is a very low degree of multicollinearity among independent variables, with a mean Variance Inflation Factor (VIF) of 1.49. In a regression model, five variables are correlated to the dependent variable, which are all from the demographic profile of the respondent. It includes age, gender, monthly income, household monthly income and number of years living in the area. The average willingness to pay is Php 23.85, which is what respondents paid monthly for Basak Lake protection. The payment for the protection of Basak Lake can generate Php 109,324,931 annually.
