Description: This geo-dataset assigns 18 primary geologic units to the 2014 Missouri Natural Glades shapefile. It also represents the next iteration of the 2014 version increasing the previous number of glade polygons by 9,200 and the total acreage by over 23,500. Within the last four years, improved imagery and the expansion of mapping in several new counties resulted in these additions. The revised mapping and addition of more accurate geology shapefiles permitted the assignments of specific geologic units to the glade polygons. The American Bird Conservancy provided access to ArcMap to complete this project. The geo-dataset is designed to represent concise locations for the statewide distribution of Missouriâs principal glade-producing rock formations for dolomite, limestone, sandstone, igneous, shale and chert bedrock. The authors interpreted various imagery, geologic and topographic maps then conducted field surveys to validate mapping interpretations in various glade-producing landscapes. All of the glades can be readily cross-referenced to their respective natural community based on the delineation of the rock type incorporated into the geologic unit name. For example: Roubidoux, Lamotte, Channel, and St. Peters are all sandstone glade natural communities.
