Highly erosive soils are those soil map units that have a severe erosion hazard rating for forest
management as listed in the Digital Soil Database of the Hoosier National Forest (USDA NRCS
2001). Following is a list of Hoosier National forest soil map units that have a severe erosion
hazard and therefore are considered highly erosive soils.
