The Gravel Hill Prairies of the Wabash River Valley in the vicinity of Lafayette, Indiana are an endangered habitat in the state of Indiana (currently only three locations are known) and provide optimal growing conditions for a number of state endangered plants. Previous studies conducted in the 1980’s attempted to locate additional gravel hill prairies, with little success. These unique ecosystems have been found to occur almost exclusively on soils classified as Rodman Gravelly Loams and complexes thereof (i.e. Strawn-Rodman complex) which occur along the Wabash River’s outwash terrace. This volunteer research effort aims to determine potential areas of undiscovered gravel hill prairie remnants to develop a strategy to scout areas identified with the highest probability of occurrence for acquisition and conservation of said ecosystems. To date, Geographic Information Systems (GIS) such as ArcGIS and geospatial datasets such as the USDA’s Gridded Soil Survey Geographic (gSSURGO) for the state of Indiana have not been used to attempt and locate additional gravel hill prairies. This volunteer research effort relied on spatial analysis with GIS and numerous databases (like the USDA’s gSSURGO product) to develop maps and plans of potential areas to scout.
