The Lake Michigan Lakewide Action and Management Plan (LAMP) is a collaborative, adaptive management program where federal, state, tribal and local governments along with other partners work together to protect and restore Lake Michigan. The LAMP shares responsibility for implementing many aspects of the Great Lakes Water Quality Agreement (GLWQA), which seeks to "restore and maintain the chemical, physical, and biological integrity of the Waters of the Great Lakes '- One commitment under the GLWQA is to develop and implement lakewide habitat and species protection and restoration strategies. Green Bay is the area in the northwest portion of Lake Michigan, separated from the Central Basin by the Door Peninsula, Garden Peninsula and the chain of islands lying between them. It includes the Wliitefish Channel and Fan and is the largest embayment in Lake Michigan. Native American Tribes and lands within this portion of the Lake Michigan basin include Forest County Potawatomi, Sokaogon Mole Lake Community, Menominee Indian Tribe, Stockbridge Mimsee Community, and Oneida Tribe of Indians. Green Bay hosts a variety of diverse plants, animals, and land forms. Several tributaries serve as spawning areas for Lake Sturgeon Wliitefish and Northern Pike. Green Bay contains an abundance and diversity of wetland-dependent bird species. Several islands support rare species of plants and animals. Coastal and shoreline areas provide habitat for birds and waterfowl. Currently^ 65% of coastal land in the Green Bay region is in natural land cover, and 81% of shoreline area provides suitable habitat for landbirds. Collaboration among partners in the Green Bay area is needed to implement key actions that will maintain and increase the viability of biodiversity and abate identified threats to biodiversity. Threats to Biodiversity In an assessment of threats to biodiversity, numerous experts rated the current viability status of an array of targets using recognized Key Ecological Attributes and indicators of viability (Table 1). Critical threats to biodiversity in the Green Bay area include lost hydrological connections, aquatic and terrestrial invasive species, and runoff from development and concentrated agricultural facilities. Invasive species can alter ecosystem attributes, such as water clarity and nutrient levels, and present serious threats to native species. Disjointed hydrologic connections between coastal wetlands and the lake threaten access to critical spawning areas along the west shore of Green Bay. Physical alteration of the shoreline from housing and urban development has a critical impact on the nearshore zone, wliich supports diverse fish and invertebrates, and on coastal terrestrial systems that support important plant and animal species. Excessive nutrient loading from runoff lias contributed to the low dissolved oxygen (hypoxia) condition in Lower Green Bay. Table 1.

The following strategies are recommended. For additional details, see Chapter 6 of the Lake Michigan Biodiversity Conservation Strategy. Strategies for Very High Threat Targets: • Improve land use practices to minimize detrimental impact: o Increase adoption of conservation practices to address the impacts of agricultural and urban water pollution, o Develop and implement collaborative land-use planning efforts that integrate green infrastructure principles into shoreline alterations. • Increase habitat connectivity by: o Increasing planning for projects jointly developed by transportation and environmental agencies to increase the adoption of best practices for constructing road-stream crossings, o Working to incorporate context-sensitive design in transportation projects involving dams and fish ladders, o Ensuring contiguous habitat for terrestrial migratory species. • Align projects among Lake Michigan states to implement common policies, risk assessments, and funding that will minimize invasive species. • Support the continual development of early detection and rapid response plans for invasive species. Strategies for High Threat Targets: • Maintain critical habitat on islands and coastal areas: o Conduct periodic surveys to assess the status of critical habitat and important species. o Implement outreach and education focused on how shoreline management activities may affect coastal ecology, o Develop sustainable remediation designs that restore coastal and shoreline habitat. • Support restoration of offshore fish and fisheries by: o Initiating a pilot stocking program in Green Bay to achieve self-sustaining populations of Cisco (Lake Herring), o Assuring that funding for lamprey control continues at or above current levels. • Continue efforts to remediate two designated Areas of Concern (AOCs): o Restoring the Cat Island Chain of islands in the Fox River/Lower Green Bay AOC will strengthen the ecosystem foster a diversity of habitat for migratory birds and various fish species, and enhance spawning grounds for fish, o In the Menominee River AOC, remediation of areas contaminated with arsenic and polycyclic aromatic hydrocarbons (PAHs) will protect wildlife and fish habitat in nearshore and wetland areas. The Great Lakes Restoration Initiative (www.glri.us/) has supported habitat and species protection and restoration efforts and will continue to serve as an important mechanism for implementing biodiversity conservation strategies in the Green Bay area.
