Streamside Conservation Authority Rasters, Okanogan County, WA, USA

These raster datasets were generated and analyzed during the study described by Stahl, Fremier, and Cosens (2020) in Conservation Biology, entitled "Mapping legal authority for terrestrial conservation corridors along streams". Each source of streamside conservation authority in the study area was mapped as a feature class (polygon) and then converted to raster, such that pixel values in each raster correspond to the conservation authority index (CAI) value associated with the respective source of authority. We used these rasters to generate a legal-ecological resistance surface for least-cost corridor computation. A similar approach may be useful in many settings to incorporate legal or other social data sets into habitat assessments for conservation planning.

本批栅格数据集（raster datasets）由Stahl、Fremier与Cosens于2020年发表于《保护生物学》（Conservation Biology）期刊的研究中生成并分析，该研究论文题为《沿溪流构建陆地保护廊道的法定权限制图》（Mapping legal authority for terrestrial conservation corridors along streams）。研究区域内每一处滨岸保护权限来源均先被制图为要素类（feature class，类型为多边形（polygon）），随后转换为栅格数据，各栅格的像素值均与对应权限来源的保护权限指数（Conservation Authority Index，CAI）一一对应。我们利用这批栅格数据，生成了用于最小成本廊道（least-cost corridor）计算的法定-生态阻力面。该方法可推广至诸多应用场景，用于将法定或其他社会数据集纳入保护规划的生境评估工作中。如需获取更多研究细节，请参阅该已发表论文。
