Predicted population cores (25%, 50% and 75%) of breeding thick-billed longspur (Rhynchophanes mccownii) based on a range-wide random forest distribution model. We summed the probability of occurrence across all pixels in the study region to generate an index of total population. We placed each grid cell prediction in the context of the study area by dividing the individual pixel probability by the total index. Starting with the highest-value pixels, we cumulatively summed the probabilities until a given threshold was met. We set 25, 50 and 75% thresholds to delineate cores as the smallest possible areas containing the highest concentrations of predicted birds.
Documents data sources and process steps for creating Phase 2 Spatial Designs for the Crown of the Continent Landscape Conservation Design
The Alberta wall to wall land-cover (LC) polygon vector layer circa 2010 (ABMIw2wLCV2010), version 1.0, is a map describing the spatial distribution of LC across the province of Alberta for the reference year 2010. The map legend consists of 11 LC classes (see below), and the map itself (i.e., this feature class) consists of a mosaic of roughly a million non-overlapping polygons of various sizes, from half a hectare (ha) to thousands of ha. The minimum mapping unit (MMU, or minimum polygon size) is 0.5 ha for aquatic features and 2 ha for the rest, and the Minimum Mapping Width (MMW) is two Landsat pixels (60 m). The file format chosen for the ABw2wLCV2000 is ESRI file geodatabase (gdb), and the cartographic projection...
The Crown Managers Partnership (CMP) is coordinating the Crown of the Continent Landscape Conservation Design (LCD) process to help land managers collectively achieve landscape-scale ecological objectives while working within agency and organizational jurisdictions and mandates. By bringing stakeholders together, the LCD provides the opportunity for land managers to prioritize and coordinate actions on the ground. Representing 42 stakeholder entities across 31,000 sq km (50,500 mi2) in Montana, Alberta, and British Columbia, we are developing spatial designs for 15 priority landscape features. Spatial design integrates stakeholder and subject matter expert knowledge and objectives of resource management plans with...
