This course is intended to amplify your knowledge of wetland delineation, particularly in problem areas such as agricultural fields and other human disturbances. We will also discuss problem soils found in the region. This field class is intended for persons who have taken a beginner’s class in wetland delineation. After a brief catch up on your knowledge of basic principles of delineation we will focus on “Chapter 5- Difficult Wetland Situations in the Northcentral and Northeast Region”( Regional Supplement -USACE, 2012). We will learn from real-world situations how to approach a difficult delineation. The Off-Site Map Review will be taught and practiced to determine hydrologic indicators in agricultural fields. We will look at disturbed soils and how to evaluate them.
