ABSTRACT
Understanding the Wetland Data Ecosystem: Different Approaches and Outcomes
Wetland geospatial data are increasingly important in light of current and future challenges around water quality, natural disaster mitigation, food and water security, conservation planning, and more. A wide-array of geospatial products can be used to support decision-making around wetlands –– from those that highlight where wetlands might be to those that identify specific wetland types and boundaries. These products are created for distinct geographies using varying wetland definitions and approaches. As a result, they map different areas and have contrasting levels of detail and accuracy. Through four unique perspectives, this webinar outlines the basic differences and relationships between wetland geospatial datasets, highlighting how they can be leveraged to best address user requirements.

Megan Lang is Chief Scientist for the U.S. Fish and Wildlife Service National Wetlands Inventory Program and Project Lead for the Wetlands Status and Trends study. She is an Adjunct Professor at the University of Maryland Department of Geographical Sciences and serves as an Associate Editor for the journal Wetlands. Dr. Lang has been working to improve the assessment of aquatic ecosystems through field and remote sensing studies for over two decades. Before working for the U.S. Fish and Wildlife Service, she led the U.S. Department of Agricultural Mid-Atlantic Regional Wetland Conservation Effects Assessment Project
Robb Macleod is the National GIS Coordinator for Ducks Unlimited. He has been working for Ducks Unlimited in the GIS and Remote Sensing field for over 25 years. His current duties include coordinating all of the geospatial activities for Ducks Unlimited. Robb has been active in mapping wetlands in the Great Lakes for over 19 years with previous experience mapping wetlands and land cover in Alaska.
Andy Robertson is currently Executive Director of GeoSpatial Services at Saint Mary’s University of Minnesota. In this role, Andy is responsible for oversight and management of all GeoSpatial Services projects, activities and staff. GeoSpatial Services is engaged in a wide variety of projects across the Lower 48 and Alaska including: Catholic Church properties data driven decision support, wetland inventory and functional assessment, national hydrography dataset updates; stakeholder consultation; and natural resource condition assessments. Andy has been a key partner of the USFWS, working for over 20 years to update legacy National Wetland Inventory data across the nation. He earned a Forest Technology Diploma from Sault College of Applied Technology in Ontario, Canada, a B.Sc. in Environmental Science from the University of Waterloo and completed postgraduate work in forest management at the University of Toronto. He is a board member for the National Association of Wetland Managers, steering committee member for the NAWM Wetland Mapping Consortium, Member of the American Rivers Functioning Floodplain Alliance, President-Elect of the Society of Wetland Scientists North Central Chapter and past chair of the Alaska Wetlands Technical Working Group.
Meghan Halabisky is a co-founder of TealWaters and a Research Scientist at the University of Washington, specializing in remote sensing and geospatial analysis for wetland conservation. She holds a PhD in Remote Sensing and Geospatial Analysis from the University of Washington, where her research focuses on understanding wetland dynamics in the face of climate change and enhancing conservation strategies through cutting-edge spatial tools. She leads the NASA Carbon Monitoring System Science Team WetCarbon working group and serves as a Senior Science Advisor for Digital Earth Africa, working to support countries to develop national wetland inventories. Dr. Halabisky works closely with tribal governments, policymakers, and natural resource managers to promote equitable, nature-based solutions.
