Members' Wetland WebinarThe 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.

Developing a New Ecological Site Description for Karst Fens

Wednesday, September 29, 2021 - 3:00 p.m. – 4:30 p.m. Eastern

PRESENTER

  • Frank Nelson, Missouri Department of Conservation

ABSTRACT

This webinar will present Missouri Department of Conservation (DEC) recent work to develop a new ecological site description for karst fens. Building off of the work focused on one of Missouri's unique natural communities, we have spent time in the field and literature formalizing and developing the new Ecological Site Description. for Karst Fens are geographically isolated wetlands driven by diffuse groundwater discharge and found scattered throughout the many river hills of the Ozark Highlands of Missouri. The ecological site is defined by a complex relationship among geology, hydrology, landforms, soils, biota, and natural history. DEC’s synthesis has articulated the ecological processes, natural variability, and potential transition states that occur on the landscape. The ecological site description should help direct actions and funds towards further conservation, management, and restoration of these unique habitats on public and private land in the future. The webinar will conclude with ideas for new paths for research that could further our understanding and have identified similar communities in karst landscapes within neighboring states where this collaborative research could be beneficial for groundwater wetland conservation as a whole within mid-latitude states. Participants will have the opportunity to participate in a Q&A session with the presenter.

BIO

Frank Nelson, Missouri Department of ConservationFrank Nelson has worked for over the last 17 years for the Missouri Department of Conservation as a Wetland Ecologist where his focus has been applying research and technology to enhance wetland management, monitoring, and restoration. During the last few years, Frank led a group of state and federal partners to develop a geo-spatial dataset for Missouri's 10.4 million acres of bottomland habitat. He has also been working with DEC to develop a new ecological site description for karst fens in Missouri.

Megafires Be Dammed: Can Beaver-created Fire Refugia Persist Through Extreme Wildfire Events?

PRESENTER

ABSTRACT

Megafires, defined here as fires with burn areas greater than 100,000 acres, are partially the result of increasingly short wet seasons coupled with hotter, drier summers, year after year. Though megafires historically are rare, they have become increasingly common in recent years. Megafires often pose unique challenges – they can have explosively fast rates of spread, generate their own self-sustaining weather systems, and can easily cause secondary ignitions in the surrounding landscape via ember spotting and lightning strikes from pyroculumus clouds. Managing fires of this size and intensity while preserving sensitive riparian ecosystems is a landscape-scale challenge. Beaver activity has been previously shown to keep riparian vegetation green and lush during both droughts and small to medium-sized wildfires. Whether or not this effect persists in megafires has not been previously studied. We use Sentinel-2 remote sensing data (false color 8,4,3; false color 12,11,4; and NDVI), Landsat 8 remote-sensing data (NDVI), remote-sensing based evapotranspiration modeling (METRIC model), and high resolution true color satellite and aerial imagery to characterize fire spread and burn patterns in and around beaver-dammed riparian zones within several megafire burn perimeters from the 2020 and 2021 fire seasons. Our analyses suggest that beaver-created fire refugia can persist through megafires, and that the degree of fire protection is typically greater in 1) active beaver areas, 2) in beaver complexes with multiple dams in close proximity, and/or 3) where extensive active or historical beaver damming has created an anastomosing channel and/or a wide network of beaver-dug canals.

Dr. Emily Fairfax is an Assistant Professor of Environmental Science and Resource Management at California State University Channel Islands. Dr. Fairfax double majored in Chemistry and Physics as an undergraduate at Carleton College, then went on to earn a PhD in Geological Sciences from the University of Colorado Boulder. She uses a combination of remote sensing and field work to research how beaver activity can create drought and fire-resistant patches in the landscape under a changing climate. Her colleagues and students can vouch that when Dr. Fairfax says she can talk about beavers all day, she’s not kidding.
