CNH-L: Coupled Social and Ecological Consequences of Conservation Easements

保护地役权是一种私人土地保护工具，在过去的30年里，它在美国得到了广泛的使用，它的流行可能与税法相对应，税法为公共利益创造了私人土地保护的激励措施。本研究项目将探讨如何保护地役权持有人，地役权捐助者/卖方，区域土地利用的压力，并连接到保护土地之间的动态变化正在影响美国不同地区的保护地役权的空间格局，公共利益和生态完整性。这些动态将在细尺度上加以审查;国家和区域政策结构将在地块一级联系起来。将分析在保护地役权过程中的公共投入如何影响地役权的空间使用，以及地役权对相邻和县级土地成本的邻里效应。这项研究的结果将是有用的土地利用规划者，公共和私人，谁将受益于更好地了解运输过程和环境的结果。学生将接受数据库创建和评估方面的培训，加强国家的科学劳动力。采用多元，空间叠加，和时间序列分析，政治和法律的因素和保护地役权传播之间的关系将被检查。区域空间数据集将结合县级地役权捐助者调查的结果和精细和粗过滤器生态完整性的方法，以评估是否保护地役权，其目的是保持生物的完整性有更高的可能性，以促进储备网络的空间安排比其他保护地役权。这种情况是否更有可能发生在地役权安置过程中有公众监督的地区，将予以确定。环境结果如何影响地役权决策过程将得到解决。理论将通过研究地役权工具的地理效应，以及社会因素如何影响其使用，在一个单一的空间和定量框架。更广泛的影响将包括规划者和土地所有者更好地了解完整的保护地役权过程，以及对本科生和研究生的培训。

A private land conservation tool, conservation easements, have become widely used in the United States over the past thirty years, and their popularity may correspond to tax laws creating incentives for private land conservation in the public interest. This research project will examine how shifting dynamics between conservation easement holders, easement donors/sellers, regional land use pressures, and connections to conserved lands are affecting the spatial pattern, public benefit and ecological integrity of conservation easements in different regions of the United States. These dynamics will be examined at the fine scale; national and regional policy structures will be linked at the land parcel-level. How public input during the conservation easement process affects the spatial use of easements, as well as the neighborhood effects of easements on adjacent and county-level land costs, will be analyzed. Results from this research will be useful to land use planners, both public and private, who will benefit from a better understanding of the conveyance process and the environmental outcomes. Students will be trained in database creation and assessment, strengthening the nation's scientific workforce. Employing multivariate, spatial overlay, and time-series analyses, the relationship between political and legal factors and conservation easement propagation will be examined. Regional spatial datasets will be combined with the results from county-level easement donor surveys and both fine and coarse filter ecological integrity approaches to assess whether conservation easements whose purpose is to maintain biological integrity have a higher likelihood of contributing to reserve networks in their spatial arrangement than do other conservation easements. Whether this is more likely to occur in areas with public oversight in the easement placement process will be determined. How the environmental outcomes affect the easement decision process will be addressed. Theory will be advanced by examining the geographic effect of the easement tool, and how social factors may influence its use, in a single spatial and quantitative framework. Broader impacts will include better understanding of the complete conservation easement process for planners and land owners and the training of undergraduate and graduate students.
