Basic Wetland Delineation Refresher Course
Course Overview
The Wetland Delineation Refresher is the field portion of WTI’s Basic Wetland Delineation program, for people who want a refresher on field practices. It has no lectures. Instead it is intensive field work, offered in two formats:
2-Day Field Training: 16 contact hours (in-field)
Tuition: $750
3-Day Extended Field Training: 24 contact hours (in-field)
Tuition: $850
Offered at select locations. Where it’s offered, we strongly recommend the 3-day option.
The third day takes you to new field sites, usually with a smaller group and more one-on-one time with the instructor. You go deeper into soils: describing soil layers, practicing soil texturing and identifying more hydric soil indicators. You also work through a problem situation, such as a grazed pasture, that often trips up delineators. And you spend more time using hydrology and landscape position to refine the boundary when vegetation alone isn’t enough.
Field sessions run from 8:00 a.m. to 5:30 p.m. each day unless noted otherwise. Lecture slides can be downloaded, and a discussion board is open before and after the course.
This course is open to those who have had a full, basic wetland delineation course (at least 32 instructional hours) in the past and want a refresher on field practices. This course alone does not satisfy the requirements for basic delineation training as specified by the U.S. Army Corps of Engineers. If you are looking to satisfy those requirements, you need to check out WTI’s other courses: Basic Wetland Delineation or Basic Wetland Delineation – Extended Field Training.

Recommended Plant Identification Courses (Optional)
Once you learn delineation, the best way to increase your efficiency is to learn to rapidly identify plants in the field. Our Plants of the Wetland Boundary (PWB) online courses are designed for non-botonists that want to improve their delineation skills. Learn about individual regional courses by clicking the buttons below, or click here to purchase our 3 region bundle (includes Northeast, North Central, Southeast). You can take all three regions currently available for just $1,150! You can also browse all of our plant identification courses here.

Certificate of Completion
You will receive a certificate of completion with instructional contact hours documented once you have completed all course requirements (i.e. online lectures, field practicum, discussion forum participation).
Frequently asked Questions
Can I have face-to-face interaction with Instructor?
You will have face-to-face interaction with your field practicum instructor to ensure you understand all the material as well as standard field practices. You also have access to the instructor via the online discussion board or our direct messaging system from the member’s area.
Does this course count towards my certification program?
Your certificate of completion can be used to document instructional hours received in this topic. You should contact the specific certifying agency or association directly to find out how they will assess or credit this WTI course. Typically, our courses are accepted by all state and national certifying agencies and associations; however, you should confirm that with the specific certification program to which you are applying or renewing.
Do I need to take a field course in the state/region where I work?
The basic wetland delineation courses focus on data collection, field interpretations and wetland boundary determination. While plant identification and habitat discussions are informally part of the course, they aren’t the primary focus. In many situations, the instructor or other participants point out specific plants, but don’t have time to explain the particulars for the trees, shrubs, forbs, grasses and vines. If there isn’t a quick identification, then the class proceeds with noting the genus but not species. Thus, field sessions are not State-centric for plants or habitat.

What our participants say…
“Thank you again for a great Wetland Delineation Refresher Course. I enjoyed it thoroughly and got a lot of good info out of it. I have been doing delineations for some time; however, my gut was telling me it was time to get some new/updated info, and your course provided that.”
“The instructor knows the 1987 USACE Manual inside and out and is an expert in the field of wetland delineation. I would recommend this course to anyone wishing to expand their knowledge on the subject.”
Course Curriculum
This Basic Wetland Delineation Refresher course consists of a 2-day Field Practicum focused on the application of the Regional Supplements and the portions of the 1987 Wetland Delineation Manual still valid as used by the Army Corps of Engineers (Corps) and numerous state governments. This course is designed for individuals who have had a wetland delineation course in the past and would like to revisit field techniques and best practices.
