- Site floods or ponds
- Organic soil that does not flood or pond
- Organic soil with 0 to 40 centimeters of organic matter underlain by mineral sediments that can have frequent ponding for up to 9 months. Includes soils with 20 to 40 centimeters organic material (Histic Humaquepts) and sites with less than 20 cm of organic material. Can also include sites with mucky modified mineral surface texture that occur in depressions that dry out in summer

Zoom in to display soil survey map units for an area of interest, and zoom out to display MLRAs. Select a map unit polygon to view ecological sites correlated to that map unit. View a brief description of an ecological site by clicking on its name in the map popup. Soil survey correlations may not be accurate, and ecological site classification of a location should always be verified in the field. Each selection may require the transfer of several hundred KB of data.
