About the FPC Forest Soil Classification System
Soils are classified to communicate characteristics that often denote what management techniques might be required. However, the United States Department of Agriculture’s widely accepted taxonomy system is not tailored specifically to forest management.
A new classification system constructed by the Forest Productivity Cooperative (FPC) provides a more comprehensive assessment of factors known to influence forest response to management practices such as underlying geology.

About the Web Map
The FPC Web Map is based on the FPC soil classification system and includes supplemental data sources such as USGS geologic formations, Major Land Resource Areas, and more to help inform silvicultural prescriptions. Data sets have been meticulously analyzed and constructed to be top-tier resources for informing decisions in relation to forest management.

2.0.0 — Current Version
- Consolidated geology
- Added CRIFF Group for Translation
- Simplification of Major Soil Groups
- Separate depth code from subsoil texture

The State Geologic Map Compilation (SGMC) Geodatabase of the Conterminous United States (ver. 1.1, August 2017): The State Geologic Map Compilation of the Conterminous United States was developed by the U.S. Geological Survey Mineral Resources Program (MRP). The project owes its success to numerous MRP staff who compiled the Preliminary Integrated Geologic Map Databases for the United States (PIGMD) as well as the foundational geologic mapping work completed by U.S. State Geologic Surveys and academia. Data obtained and used via SGMC was not spatially manipulated — only added onto via delineation of nutrient status and how major geologic formations correlate to FPC’s classification system taxonomy.
-> The “Terraces, Atlantic Coastal Plain” layer extends beyond the Atlantic Coastal Plain, despite blatant claims made in its title. This is a vector geometry issue that will be repaired in the next update as the layer makes a stark return to raster.
-> Depending on the exact version of source file being used, the Citronelle formation may improperly appear in Georgia. This should be Atlantic Upper Coastal Plain Terrace and will be corrected in the next release. Note that this has been already fixed in the “Geology only” versions and also individual county versions.
-> Modifier 3:c and Modifier 3:n, Alkaline/calcareous and Salt affected/natric respectively, are being underrepresented across the landscape. This will be corrected in the next release.
