Abstract

The whitebark pine (.) tree species faces precipitously declining populations in many locations. It is a keystone species found primarily in high-elevation forests across the Western US. The species is an early responder to climate change and qualifies for endangered species protection. We use contingent valuation to estimate the public's willingness to pay for management of the whitebark pine species. In contrast, previous work centres on valuing broader aspects of forest ecosystems or threats to multiple tree species. While only approximately half of the survey respondents have seen whitebark pine, the mean willingness to pay for whitebark pine management is $135 per household. When aggregated across all households from the three sampled states, willingness to pay totals $163 million. This information is valuable to forest managers who must make difficult decisions in times of resource constraints and climate change.

摘要

白皮松这一树种在许多地区的数量正急剧下降。它是一种关键物种,主要分布在美国西部的高海拔森林中。该物种是气候变化的早期响应者,符合濒危物种保护的条件。我们使用条件价值评估法来估计公众为白皮松物种管理支付费用的意愿。相比之下,之前的工作主要集中在评估森林生态系统的更广泛方面或对多种树种的威胁。虽然只有大约一半的调查受访者见过白皮松,但每户家庭为白皮松管理支付费用的平均意愿是135美元。当汇总来自三个抽样州的所有家庭时,支付意愿总计达1.63亿美元。这些信息对于在资源受限和气候变化时期必须做出艰难决策的森林管理者来说非常有价值。
