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.

Future Members' Webinar Schedule

ASWM Members webinars are generally held the fourth Wednesday of the month unless the date and time needs to be adjusted for when the presenter(s) is available.

If you haven’t used Go To Webinar before or you just need a refresher, please view our guide prior to the webinar here.

If you would like to participate in the webinar but believe there is not enough time to join and register, please contact Laura at or call 207-892-3399.

Modeling Impacts of Climate Change and Land-use Change on Prairie Pothole Wetlands

The North American Prairie Pothole Region is home to millions of glacially-derived depressions known today as prairie-pothole wetlands. These wetlands provide critical migratory-bird habitat, support dynamic aquatic communities, and provide a number of other ecosystem services. To more fully understand the complex, often interacting, influences of climate and land-use on prairie-pothole wetland systems, and to facilitate climate and land-use change adaptation efforts, and to establish a mechanistic understanding of prairie-pothole wetlands we used long-term weather, hydrology, and chemistry data to develop the Pothole Hydrology-Linked Systems Simulator (PHyLiSS). PHyLiSS is unique among other wetland models because it accommodates differing sizes and morphometries of wetland basins and allows for functional changes associated with dynamic shifts in ecohydrological states. PHyLiSS also has the capability to simulate wetland salinity, and future iterations will be able to simulate the influences of changing hydrology and geochemical conditions on biota.


Owen McKenna is a Research Ecologist at Northern Prairie Wildlife Research Center in Jamestown, ND. Dr. McKenna received a Ph.D. in Environmental Life Sciences at Arizona State University where he studied desert playa wetland ecohydrology. He also studied Great Lakes coastal wetlands and invasive cattails as an undergraduate at Loyola University Chicago. His current research is focused on studying how changes in climate and land use can alter the hydrology and geochemistry of prairie-pothole wetlands. Dr. McKenna has led the development of the Pothole Hydrology Linked Systems Simulator (PHyLiSS). He is currently using PHyLiSS to assist land managers with the U.S. Fish and Wildlife Service in estimating the future impacts of climate and land-use change on critical migratory waterfowl habitat. Additionally, Dr. McKenna is using the APEX model to integrate prairie-pothole wetlands into U.S. Department of Agriculture conservation planning efforts.
