Contingent valuation is used to examine the influence of environmental engagement and beliefs on willingness to pay (WTP) for urban forest preservation. We survey surrounding residents of two urban forest sites in Puerto Rico with distinct environmental experiences and beliefs about ecosystem services. We find that WTP for preserving the urban forest where the surrounding residents are involved in forest management is $118/year. On the other hand, WTP for preserving a larger urban forest where surrounding residents are not engaged in management is $81/year. In addition to the respondents' characteristics and environmental engagement, WTP also depends on the beliefs about urban forest ecosystem services.

条件估值用于检查环境参与和信念对城市森林保护支付意愿 (WTP) 的影响。我们调查了波多黎各两个城市森林遗址的周围居民，他们对生态系统服务有着不同的环境体验和信念。我们发现，保护周围居民参与森林管理的城市森林的支付意愿为 118 美元/年。另一方面，保护周围居民不参与管理的较大城市森林的支付意愿为 81 美元/年。除了受访者的特征和环境参与度外，支付意愿还取决于对城市森林生态系统服务的信念。
