7. The hydric soils list was formulated by applying the above criteria 

 to soil properties documented in USDA-SCS (1975) and the SCS Soil Interpre- 

 tation Records (SOI-5). 



Use of the list 



8. The list of hydric soils of the United States (Table Dl) is arranged 

 alphabetically by soil series. Unless otherwise specified, all phases of a 

 listed soil series are hydric. In some cases, only those phases of a soil 

 series that are ponded, frequently flooded, or otherwise designated as wet are 

 hydric. Such phases are denoted in Table Dl by the following symbols in 

 parentheses after the series name: 



F - flooded 

 FF - frequently flooded 

 P - ponded 

 W - wet 

 D - depressional 



9. Drained phases of some soil series retain their hydric properties 

 even after drainage. Such phases are identified in Table Dl by the symbol 

 "DR" in parentheses following the soil series name. In such cases, both the 

 drained and undrained phases of the soil series are hydric. 



CAUTION: Be sure that the profile description of the mapping unit conforms to 

 that of the sampled soil. Also, designation of a soil series or phase as 

 hydric does not necessarily mean that the area is a wetland. An area having a 

 hydric soil is a wetland only if positive indicators of hydrophytic vegetation 

 and wetland hydrology are also present. 



** NOTE - Table Dl, List of Hydric Soils has been changed and is now contained in the 

 third edition Hvdric Soils of the United States (June 1991). Copies of this publication
