Wetland Prioritization SCORTP 2012 (Top 60)

Idaho Wetland Conservation Prioritization Plan - 2012 Idaho Department of Fish and Game used GIS to prioritize wetlands for acquisition, long-term conservation, and restoration. Three broad criteria were considered: 1) wetland types; 2) wetland functions and values; and 3) wetland threats and impairments. Ecological systems known to be rare, reduced in extent, sensitive to disturbance, difficult to restore, and/or declining in Idaho were included in the wetland type criteria. The extent of these ecological systems (mapped in a 30 m2 pixel raster layer) was estimated using existing maps and vegetation plot data. Habitat function was assessed by analyzing the capacity of wetlands to support wildlife Species of Greatest Conservation Need and special status plants. Recreational values of wetlands were estimated by creating a statewide GIS model of recreational opportunity. Spatial layers mapping the extent of recreation sites were used. Idaho’s landscape-scale wetland assessment tool was used to estimate the relative condition of wetland habitats. A series of filters were used to identify wetlands of high conservation priority. The resulting layer was then reduced to clusters of pixels that were > 80 ac. This threshold was used to target larger wetland blocks whose conservation or restoration would have the largest positive impact on the health of a watershed, ecological connectivity, and local communities. Sixty large wetland complexes meeting the prioritization criteria and passing all filters were identified and included in this dataset.2012年爱达荷州湿地保护优先计划——爱达荷州鱼类和野生动物部门（Idaho Department of Fish and Game）采用地理信息系统（GIS），以湿地收购、长期保护与修复为目标开展优先级评定工作。本次评估共考量三大核心标准：1. 湿地类型；2. 湿地功能与价值；3. 湿地面临的威胁与受损状况。湿地类型标准涵盖了爱达荷州境内珍稀、分布缩减、易受干扰、修复难度高，或覆盖范围呈下降趋势的生态系统。上述生态系统的分布范围以30平方米像素栅格图层完成制图，并通过现有地图与植被样地数据进行估算。生境功能评估通过分析湿地支撑最高保护优先级野生动物与特殊保护地位植物的能力开展。湿地游憩价值的估算通过构建全州游憩机会地理信息系统模型完成，该模型依托绘制了游憩场地分布范围的空间图层。研究同时采用爱达荷州景观尺度湿地评估工具，对湿地生境的相对健康状况进行估算。通过一系列筛选步骤识别出具有高保护优先级的湿地。随后将生成的栅格图层筛选为像素集群面积大于80英亩（ac）的区域，该阈值旨在锁定面积更大的湿地区块，对这类湿地开展保护或修复将对流域健康、生态连通性及当地社区产生最为显著的积极影响。最终共有60处符合优先级评定标准且通过全部筛选步骤的大型湿地综合体被识别，并纳入本数据集。
