Wetland Delineation

Wetland Delineation is a process that requires an adequate knowledge of the hydrologic, soil and plant characteristics of wetlands to determine which parts of the landscape are wetlands and how to define their boundaries. In this course our instructors provide thorough training in the protocols covered in the 1987 US Army Corps of Engineers Wetlands Delineation Manual and its Regional Supplements. These protocols can be used to identify areas that possess the appropriate combination of wetland hydrology, hydric soils, and wetland plant communities to be considered jurisdictional wetlands.

During this course, we will cover all aspects of the wetland delineation process through classroom sessions and hands-on field training. Instructors will describe the different types of wetlands, their varying hydrologic, soil, and plant features, and how to best collect and record the important data that separates wetlands from their surrounding landscapes.

Special emphasis will be given to the field indicators of wetland hydrology, hydric soils, and wetland plant communities detailed in the Midwest, Northcentral and Northeast, and Eastern Mountains and Piedmont Regional Supplements. Delineation instruction will be presented in a format that translates into accurate and comprehensive delineations which will meet the approval of the regulatory agencies including the US Army Corps of Engineers.

Registration for all Wetland Delineation Courses includes online access to the following:

-    Field Indicators of Hydric Soils in the United States
-    1987 USACE Wetland Delineation Manual 
-    Three regional supplemental manuals for Ohio
-    NRCS Land Resource Regions
-    USACE latest regional wetland plant list 
-    Copies of training PowerPoints

Students for all courses will need to provide their own Munsell Color Soil Book and 10 x Magnifier.  Please see Equipment section to the left for additional items.

Spring Course (May 18-21, 24-25)

Due to Covid-19, we are offering our spring Wetland Delineation course in a new hybrid format consisting of virtual classroom instruction and in-field practical field training.

Please Note: Classroom instruction will be held via Zoom to ensure that we maintain safe social distancing.  Field portions will still take place; you will need to provide your own transportation to and from field sites.  You will also need to maintain appropriate social distancing and wear a face mask at all times during in-field training; MBI will provide masks if needed, and will also have hand sanitizer and hand washing stations available.

Days One to Four, May 18-21: Virtual Classroom Instruction

Classroom instruction will be broken into 4 consecutive 1/2 day (4-hour) sessions.

Days Five to Six, May 24-25: Field Training

Field Training will take place over 2 consecutive 8-hour days.

Fall Course (Sept 13-16)

We are hoping that this fall, we can resume our normal course structure.  We have scheduled this course for four days as follows:

Days One to Four, Sept 13-16: 

4 consecutive (8-hour) days - two days of classroom instruction, followed by two days of field training.


Upon completion participants will be equipped and confident in their abilities to delineate wetlands on their own and will be informed on how to access any additional guidance they may need. Participants will receive certification documenting successful course completion.

* This course is certified by the Society of Wetland Scientists Professional Certification Program.
