In much of the U.S., natural communities of native species remain largely within protected areas. The maintenance of biodiversity thus relies on how strongly native wildlife communities motivate conservation and on how effectively conservation protects wild communities. This project explores two major alternative mechanisms for this coupling between nature and society, the purchase of lands or rights by conservation organizations and legislation through ballot initiatives. Researchers will compare abundances of rare or threatened native plant species and abundances of introduced plants that tend to exclude native species in areas conserved through these different mechanisms. The study will also investigate the factors that determine whether different types of conservation actions are undertaken. The project will use California as the study system, since both mechanisms have been widely employed in the state, and a rich body of data is available. Results will inform conservation policy and help guide future protection of native species in and beyond California. Dissemination of findings will be enhanced by integration of the study with a program to bring conservation practitioners into classrooms and public forums. The project will also train undergraduate students, a Ph.D. student, and a postdoctoral researcher. This project will examine how local landscape, community and ballot characteristics influence the probability of passage of conservation measures. Researchers will also evaluate the potential ancillary benefits of public initiatives in helping to safeguard biodiversity by protecting habitats that are important for priority species and by protecting priority ecosystems through a combination of GIS analyses and ecological field surveys. The project will contrast the contribution to conserving biodiversity of parcels protected through ballot measures with those protected through a more conventional protected area acquisition strategy. Finally, researchers will apply spatial optimization methods to evaluate how land conservation efforts undertaken by large-scale actors can complement those of local-scale actors more effectively in the future.

在美国的大部分地区，本地物种的自然社区主要保留在受保护的地区。因此，生物多样性的维持依赖于强烈的野生动植物社区的促进保护以及如何有效保护野生社区。该项目探讨了自然与社会之间这种耦合的两种主要替代机制，保护组织购买土地或权利以及通过投票计划购买土地或权利。研究人员将比较稀有或威胁性的本地植物物种的丰富性，以及倾向于通过这些不同机制保守的地区排除本地物种的广泛植物。该研究还将调查确定是否采取不同类型的保护措施的因素。由于两种机制在该州已广泛使用，并且提供了丰富的数据，因此该项目将使用加利福尼亚作为研究系统。结果将为保护政策提供信息，并帮助指导加利福尼亚州内外的本地物种的未来保护。通过将研究与一项将保护从业人员联系到教室和公共论坛的计划，将增强发现结果的传播。该项目还将培训本科生，博士学位。学生和博士后研究员。该项目将研究当地的景观，社区和投票特征如何影响通过保护措施通过的可能性。研究人员还将通过保护对优先物种很重要的栖息地以及通过GIS分析和生态现场调查来保护优先生态系统的栖息地来评估公共计划的潜在辅助益处，以帮助保护生物多样性。该项目将与通过投票措施保护的包裹的生物多样性与通过更常规的保护区采集策略保护的贡献进行对比。最后，研究人员将采用空间优化方法来评估大型参与者所做的土地保护工作如何在未来更有效地补充地方规模的参与者。
