4. Both manuals provide technical guidance and procedures for identifying and delineating wetlands.

5. Where DIFFERENCES in the two manuals occur, the Regional Supplement takes precedence over the Corps Manual.

6. Wetland Definition: Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. (Federal Register 1982)

7. Hydrophytic Vegetation Hydric Soil Wetland Hydrology
Identification of wetlands is based on a three-factor approach involving indicators of:
Hydrophytic Vegetation
Hydric Soil
Wetland Hydrology

9. Landform
Examples of Landforms include: hillside, terrace, valley, sinkhole, depression, etc.

10. Refer to: Online Corps Manual, page 73. EM&P, Chapter 5
Are climatic/hydrologic conditions on the site TYPICAL for this time of year?
Refer to:
Online Corps Manual, page 73.
EM&P, Chapter 5

11. Are Vegetation, Soil, or Hydrology Significantly Disturbed? Atypical
Through Natural Events Or Through Human Activities

12. Tornado Damaged Vegetation

13. Fill Covering Native Soil

14. Beaver Dam Enhanced Hydrology

15. Are Vegetation, Soil, or Hydrology Naturally Problematic?
Problem area wetlands are naturally occurring wetland types that lack indicators.

16. Problematic Wetlands Cedar Glades Red Parent Material Derived Soils
Seasonal Wetlands (Depressions)
FACU Dominant
Recently Developed

17. Seasonally Ponded Wetlands

18. “Normal Circumstances”?
Extent of any alterations? Relative permanence of physical alteration? If left “alone”, would current site conditions remain?

19. Agricultural Fields

20. Hydrology
14 or more consecutive days of flooding or ponding, or a water table 12 in. or less below the soil surface, during the growing season at a minimum frequency of 5 years in 10. EM&P Manual, Pages 78 and 79

21. Growing Season
Two indicators of biological activity that are readily observable in the field are:
Above-ground growth and development of vascular plants.
Soil temperature (41 degrees F at 12”).
EM&P Manual, Pages 79-81

22. Begins Before Crops Planted

23. Growing Season Ends Before Bowl Season Begins

24. Hydrophytic Vegetation

26. Plot Size? Recommended 30’, 15’, 5’ radius
Adaptable to fit site conditions
Plants rooted outside plot but growing in same soil and hydrologic conditions counted for percent cover estimates.
EM&P Manual, Pages 20-23

27. National Wetland Plant List(

28. Hydrophytic Vegetation Procedures in Order
Rapid Test (All species FACW or OBL)
Dominance Test (Determine if more than 50% dominants are FAC, FACW or OBL)
Prevalence Index (At least 80% of the total vegetation cover identified)
Morphological Adaptations (For upland plants)
EM&P Manual, Pages 25-33

29. Vegetation Data Mistakes
Absolute Cover = 100% exactly
Inclusion of non-vascular plants (moss)
Incorrect 50/20 calculations
Including + and - on indicator status
Prevalence Index (PI) unnecessarily completed
PI NOT calculated by cover estimates

30. Soil

32. Always Document These Four
Depths of soil layers (20” recommended)
Matrix colors and %
Redox colors if present and %
Soil texture (Sandy or other)

33. Soil Mistakes Multiple soil pits recorded on one form
Only one soil layer recorded
% of Matrix or Redox not recorded
Texture not recorded
Inaccurate use of Red Parent Material Indicator (F21). EM&P Manual, page 72
Incorrect Indicator selected
