Key Characteristics
- Site receives additional moisture from the surrounding landscape (floodplains and terraces) and soils formed in alluvium.
- Occurs on a terrace. Flooding is rare to none (1 to 5 times in 100 years).
- Soils are somewhat excessively to excessively drained with loamy fine sand or coarser in all horizons within the particle size control section.

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.
