Basic Wetland Delineation Refresher Course

Course Overview

The field practicum portion of our Basic Wetland Delineation 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 Wetland Delineation with Emphasis on Soils and Hydrology Online with Field Practicum.

There are no lectures with the Wetland Delineation Refresher – only two days (16 hours) of intensive field work. You will receive a printed copy of lecture notes to review. You also have access to the course discussion board so you may ask questions of your instructor before and after your course as well as interact with other course participants.

The pre-requisite for this course is completion of a basic wetland delineation (at least 32 contact hours) course in the past from Wetland Training Institute, Inc. or any other provider. When registering, please identify the date, location and provider of the course in the comments/notes box.

You will receive via mail materials you should review prior to your refresher course dates. These include: printed Lecture Notes, a Pocket Guide to Hydric Soil Field Indicators, and a USB drive containing current 1987 Wetland Delineation Manual, Regional Supplements, Plant Lists, and other publications.

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.”
