  1. GIS Tools Workflow of GIS Tools to Determine Properties Suitable for Migratory Bird Foraging Sites

  2. Standardize Raster Data • Reclassify Land Cover Data (1) agriculture and (2) forested wetland as foraging_sites • Feature to Raster and Reclassify Soils as wet_soils • Reclassify NWI farmed wetlands and forested wetlands as wetlands_national • Raster Calculator (wetlands_national X wet_soils) to capture ALL wetlands at county level of detail as wetlands_county

  3. Combine Raster Data • Mosaic to New Raster Tool with input rasters in this order: 1. wetlands and 2. foraging_sites as forage_wetlands • forage_wetlands raster dataset comprised of all county wetlands that are (1) wetlands converted to agriculture and (2) wetlands with intact bottomland hardwood forests or degraded forests • Clip forage_wetlands to extent of county boundary

  4. Nesting 1 Mile Radius • GeoprocessingBuffer Tool to add 1 mile radius around nesting sites • Feature to Raster Tool to convert buffered nesting areas to raster as nesting_buffer

  5. Define Foraging Areas • Region Group Tool to distinguish groups of foraging sites in forage_wetlands dataset • Zonal Geometry as Table to get area of foraging sites using forage_wetlands dataset • Zonal Histogram WHERE “zone dataset” is forage_wetlands and “value raster” is nesting_buffer to get output of foraging sites withing 1 mile radius of nest sites called forage_near_nest

  6. Identify Suitable Properties • Join forage_near_nest to geometry table • Create new field called forage_group_ID • Join landowner parcel dataset to forage_near_nest to identify landowners of suitable properties
