Recreational specialization and ecologically responsible behaviour of Chinese birdwatchers in Hong Kong

Birdwatching is a popular nature-based recreational activity that has millions of participants worldwide. Hong Kong is an important birdwatching destination in Southeast Asia, and the number of birdwatchers visiting Hong Kong has steadily increased in recent decades. This study investigated the influences of recreational specialization on the pro-environmental attitudes and ecologically responsible behaviour of Chinese birdwatchers. Questionnaire surveys were conducted in Hong Kong, and 387 completed questionnaires were collected. The results of structural equation modelling indicate a direct positive association between the birdwatchers’ specialization and pro-environmental attitudes and an indirect positive association between their specialization and ecologically responsible behaviour. These findings suggest that understanding birdwatchers’ specialization is essential for predicting birdwatchers’ behaviour when visiting ecologically sensitive destinations. Birdwatcher specialization levels could be used to formulate visitor management strategies at birdwatching sites and to mitigate visitor impacts on avian species.     

Joint estimation of discount rates and willingness to pay for public goods

We analyze willingness to pay (WTP) for environmental programs whose time periods of benefit and repayment differ, using a net present value framework that identifies parameters of both WTP and personal discount rates. Respondents to a contingent valuation survey focusing on protection of critical habitat buffer zones for the endangered Steller Sea Lion in Alaska were asked their willingness to pay for 1-, 5-, and 15-year repayment periods. We jointly estimate the personal discount rates and WTP via maximum likelihood, and compare with a model assuming a fixed, market discount rate.
