Members' Wetland Webinar Series

ASWM Member Webinar

The Association of State Wetland Managers (ASWM) holds a webinar each month for its members. ASWM Member webinars cover a variety of topics encompassing wetland science, policy, program implementation, and legal issues. These webinars, including recordings for past webinars are available to ASWM members. If you are not a member, you are invited to join ASWM. For information about membership, click here.

August 2017 – No Scheduled Members’ Webinar

How to Work with Wetland Datasets and Communicate Statistical Findings: Lessons Learned from Work in the Trenches

Wednesday, October 25, 2017 - 3:00 p.m.-5:00 p.m. Eastern


  • TBD


This webinar will share methods to address some of the most common challenges wetland professionals face interpreting and communicating findings from data sets and statistical analyses.  Drawing on real-world data examples, the webinar will walk participants through various approaches to making findings from data analysis understandable and compelling to non-technical audiences.

Registration coming soon.

Restoration Outcomes and Reporting: An Assessment of Wetland Area Gains in Wisconsin

Wednesday, November 29, 2017 - 3:00 p.m.-5:00 p.m. Eastern


  • Tom Dahl, U.S. Fish and Wildlife Service (Retired)
  • Rusty Griffin, U.S. Fish and Wildlife Service


Billions of dollars have been spent to restore wetlands throughout the conterminous United States, leading to gains in wetland area nationwide. However, knowledge regarding the impact of these additions is limited, in part due to the lack of a centralized restoration database, varying definitions of restoration, and shifting protocols amongst restoration initiatives.

This presentation will share findings from a U.S. Fish and Wildlife Service study of 430 wetland restoration projects in Wisconsin between 2003 and 2008. The study used high-resolution photography to evaluate the restoration projects. Aerial photo-interpretation and geospatial analysis were used to determine pre- and post-project status of wetland extent and habitat type(s). Wetland extent was mapped within project boundaries and wetland area gains were identified. Wetlands were classified by cover type and hydrology to record reestablished habitats, as well as document the prevailing land use setting of the project area and compare these results to data reported by the state. The majority of wetland area gains were classified as seasonally flooded emergent marshes, and restoration sites were primarily located within agricultural settings.

The study found 39% of wetland area gains reported by the Wisconsin Department of Natural Resources (WDNR) agreed with the study’s geospatially derived data. Actual reestablished wetland area was 61% less than the reported reestablished area. These results are valuable for documenting discrepancies between restoration accomplishment reporting and change in wetland area observed, and understanding current trends in reestablishment, including habitat types, hydrologic regimes, and land use settings. Results are beneficial to resource managers by providing insight into restoration shortcomings and the over-reporting that can occur when GIS tracking is not employed.

Registration coming soon.

How to Keep Headcuts from Working their Way Up or Downstream and Destroying Wetlands

Wednesday, December 13, 2017 - 3:00 p.m.-5:00 p.m. Eastern


  • Tom Biebighauser, Wetland Restoration and Training


Controlling head-cuts is critical to protecting natural and constructed wetlands from certain destruction. This webinar will discuss techniques for controlling head-cuts affecting wetlands of every type.  Some of the techniques covered in this webinar will include soil grading, and the installation of buried vertical grade control structures made from logs and rocks to control head-cuts, both above and downstream of wetlands.


Tom Biebighauser is an ASWM member who works as a Wildlife Biologist for the U.S. Forest Service. He has restored over 1,500 wetlands in 20-States and 2-Canadian Provinces, assisting thousands of private landowners and agency personnel with the design and construction of wetlands for improving wildlife and fish habitat. He teaches practical, hands-on workshops across North America where participants learn about wetland restoration and drainage by becoming involved in the design and construction of naturally appearing and functioning wetlands. Tom has written three books about restoring wetlands A Guide to Creating Vernal Ponds in 2003, Wetland Drainage, Restoration, and Repair in 2007, and Wetland Restoration and Construction - A Technical Guide, in 2011. 

Registration coming soon.
