Lake Superior Manoomin Cultural and Ecosystem Characterization Study
Report
A variety of environmental factors threaten manoomin (wild rice) in the Lake Superior Basin, including mining, agricultural practices, hydrologic controls and climate change. On behalf of the National Oceanic and Atmospheric Administration (NOAA), Abt developed a novel, non-monetary approach to characterize the value of manoomin habitats. This includes a Habitat Equivalency Analysis (HEA) tool that, combined with cultural and ecological metrics, can be used to describe the degraded functionality of manoomin habitats in terms of the amount of equivalent habitat restoration needed to counterbalance the losses. The report demonstrates the applicability of this tool through several case studies at different sites within the Lake Superior Basin.
