NOAA-HRS: Hyperspectral Remote Sensing and Science-Based Management of Invasive Species in the Detroit River International Wildlife Refuge
The NOAA-HRS project is the extension of and enhancement to the NOAA CRSBM-DRIWR project. The overall goals of this project are to: 1) enhance our ability to assess and monitor the spread of invasives in coastal wetland ecosystems, 2) expand our monitoring of invasive species to open coastal waters, upland and prairie ecosystems, and 3) continue monitoring the control efforts of Phramites australis. Specifically, we will: 1) create a digital inventory of spectral signatures for common invasive species, other vegetation, soils, and waters within the DRIWR, 2) develop and optimize tools for identifying and delineating invasive species from hyperspectral images, 3) begin applied study of the new invasive alga, Lyngbya wollei, in the DRIWR, and 4) provide long-term monitoring of the DRIWR's Phragmites australis control efforts to assess wetland ecosystem recovery from invasion. Our data collection and analysis is designed to reflect and implement the Great Lakes Coastal Wetlands Monitoring Plan, support the DRIWR Comprehensive Conservation Plan and associated step-down plans (especially Habitat Management), and reflect the principles embodied in Strategic Habitat Conservation and adaptive management. This research will contribute to an understanding of best practices for controlling invasive species from the perspectives of maximizing ecosystem services and protecting water quality, and provide timely, useful information to DRIWR staff to aid their management of the Refuge via GIS-based decision support. Such tools and information are critical for improving the management and conservation of coastal wetlands and connected ecosystems throughout the DRIWR and the Great Lakes region.
