Wetland Delineation Workshop: May 25–June 15, 2023

Cattails along a road.

About the format:
The workshop will be offered in a hybrid format utilizing online formats and in-person training in the field. Fieldwork will be completed in La Crosse, Wisconsin. Please review the agenda for details.

May 25–June 7, 2023
Online asynchronous sessions will be available in Canvas, the online course platform used by the UW System. Instructions for accessing the Canvas course will be sent closer to the start date.

June 8, 2023
Live online lectures will be available via Zoom links in the same Canvas course in which you completed your asynchronous online sessions.

June 13–15, 2023
In-person field work will be completed in La Crosse, Wisconsin. A central meeting point, along with hotel room block details will be confirmed soon.

What you will learn

The Hybrid Wetland Delineation workshop provides participants with a background in wetland hydrology, vegetation, soils, and gives students a solid understanding of USACE wetland delineation methods and protocols. Difficult to delineate situations, current offsite review guidance and tools, report writing, and field data collection are also covered in the more than 36 hours of instruction. Instructors are multi-agency regulators and scientists from the region. Online recorded lectures, other online activities, and a live online session will prepare students for hands-on learning in the field. The new format provides greater flexibility in gaining background knowledge and lets us focus on hands-on experience in the field during the in-person days.

Hybrid Wetland Delineation takes the place of the Basic and Advanced Wetland Delineation Training Workshops previously offered at UWL. This course will satisfy the training requirement of the WI DNR application for assurance.
