The St. Louis River Estuary including Duluth-Superior Harbor is the largest estuary in the Great Lakes as well as an Area of Concern. Several beneficial use impairments are legacies of industrial activities and have been the focus of sediment remediation and habitat restoration for many sites throughout the estuary. Natural resource management strategies in the St. Louis River estuary are currently transitioning from federal Area of Concern program priorities to longer-term monitoring and maintenance responsibilities led by the state. Habitat conditions are being documented estuary-wide in order to identify areas of habitat warranting further protection or restoration. A suite of physical, chemical, and biological data sets were used in an analysis effort that describes a gradient of environmental condition across eight longitudinally-defined geomorphic zones within the estuary. Statistical and spatial analysis techniques were used to create rankings based on individual measures of environmental health compared to an established least-impaired, reference condition. Healthy vs. poor habitat can be identified by combining associated metrics and visualizing in GIS. This conceptual tool can help advance planning within an estuary to inform managers of locations warranting protection, or further restoration. [ABSTRACT FROM AUTHOR] |
