GIS Tools

Workflow of GIS Tools to Determine Properties Suitable for Migratory Bird

Foraging Sites

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

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

Nesting 1 Mile Radius

• Geoprocessing Buffer Tool to add 1 mile radius around nesting sites

• Feature to Raster Tool to convert buffered nesting areas to raster as nesting_buffer

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

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
