Functioning floodplains provide many ecosystem services, including sediment and nutrient storage, groundwater recharge, and habitat for a diverse array of species. Many floodplains across the Lake Champlain Basin require restoration in order to function effectively. Prioritization of these projects requires a more granular assessment of floodplain characteristics. This is where a research team working out of the University of Vermont comes in.
An investigation led by Dr. Elizabeth Doran is working to establish the link between physical landscape (geomorphic) characteristics, floodplain features, natural communities, and habitat function.
While large-scale mapping tools help identify potential habitat locations, on-the-ground research is needed to confirm whether these areas are truly functioning as critical habitats. By studying the relationship between floodplain characteristics, plant communities, and the presence of key wildlife species, this research will refine how stakeholders assess and prioritize conservation projects.
A key focus is on river corridors, which serve as essential pathways for wildlife movement and habitat connectivity. The project will use occupancy modeling, a method that accounts for species presence even when they are difficult to detect, to evaluate the health of floodplain habitats. This research will support Vermont’s Functioning Floodplain Initiative (FFI), a tool used to guide restoration decisions based on flood risk reduction and water quality benefits. By adding habitat functionality as a third pillar of this initiative, the project will provide a more comprehensive approach to prioritizing restoration efforts.
The study will focus on the Lewis Creek watershed, which includes a diverse range of floodplain environments and has undergone some restoration efforts. By analyzing this area, researchers can assess how different levels of land use change impact floodplain health over time. The project will also engage a broad network of stakeholders, including state and federal agencies, conservation groups, and local watershed organizations, to ensure that findings are widely shared and used to inform decision-making. Ultimately, this research supports broader conservation goals, helping to improve water quality, enhance habitat for native species, and build resilience to flooding in the Lake Champlain Basin.
