Please join the Maine GIS User Group (MEGUG) on Tuesday, December 7 at 12:00pm as we welcome Angie Brewer (Maine DEP) and Kristen Puryear (Maine Natural Areas Program) for our next Lunch & Learn event. Register through Zoom: https://us02web.zoom.us/webinar/register/8516372722592/WN_shiETclqQpiFmI35Wihzwg
Part 1: Kristen Puryear-Tidal Marsh Mapping in Maine: Status and Looking Ahead
The Maine Natural Areas Program (MNAP) has mapped over 22,000 acres of tidal marsh in Maine through a combination of desktop review and field survey. From ecological integrity assessments and restoration planning to marsh migration modeling and coastal carbon accounting, the data are being used across multiple planning and management actions. Kristen will discuss MNAP’s tidal marsh mapping methods and applications, and identify data gaps and future monitoring needs.
Part 2: Angie Brewer-Seagrass Mapping in Maine: Opportunities and Outcomes
The Maine Department of Marine Resources (DMR) mapped intertidal and subtidal eelgrass along Maine’s coastline twice during the 1990s and 2000s using plane-acquired orthoimagery. Since 2013, the Maine Department of Environmental Protection (DEP) has continued efforts to inventory eelgrass on a more focused geographic scope, predominantly in Casco Bay. With the Maine legislature’s passing of LD 593 in 2021, DEP will manage coastwide mapping of seagrass and enhancements to existing salt marsh inventory, starting in 2023. Angie will outline the history and anticipated future of coastal seagrass and salt marsh mapping in Maine, identifying potential applications for new technologies and the myriad applications for data and GIS products, and solicit ideas for how to most optimally document and visualize vegetation change analyses for multiple users.
