Private forests in the southeastern US are critical for providing a variety of ecosystem services, including timber production and water resource protection. Restoration of longleaf pine (LLP) forests and savannas tends to enhance some ecosystem services, including water supply, over timber production. A variety of payments for watershed services (PWS) strategies have emerged to address the market failure associated with private forests and public water supply. The nature of these programs suggests that biodiversity protection may be a positive externality, or third-party benefit, to water resource protection. This paper uses a critically engaged research approach and expert interviews to investigate how PWS programs may help prevent land use change and promote LLP restoration. We also offer recommendations on how to sustain emerging efforts to implement PWS strategies while including LLP restoration objectives.

分水岭服务付款可以帮助恢复长叶松树吗？批判性研究方法

美国东南部的私人森林对于提供各种生态系统服务（包括木材生产和水资源保护）至关重要。恢复长叶松（LLP）森林和热带稀树草原往往会增强某些生态系统服务，包括供水，超过木材生产。为了解决与私人森林和公共供水相关的市场失灵，已经出现了各种分水岭付费服务（PWS）策略。这些计划的性质表明，生物多样性保护可能是水资源保护的积极外部性或第三方利益。本文使用批判性研究方法和专家访谈来研究PWS计划如何帮助防止土地用途变化和促进LLP恢复。
