Our Goal

The Great Lakes Coastal Assembly has collaboratively set four shared goals to achieve healthy coastal wetland systems:

  1. Great Lakes coastal wetlands have a balance of native species
  2. Priority species and non-desirable species are at acceptable population levels
  3. Natural shoreline is at acceptable levels
  4. Sufficient amount and diversity of healthy coastal wetlands

Our Solution

The Great Lakes Coastal Assembly, in partnership with Blue Accounting, is working to address the problem of lost and degraded wetlands. We support coastal wetland restoration, enhancement, and protection efforts in the Great Lakes basin by providing decision-makers with a clear picture of the work, and resulting impacts, occurring throughout the region.

By collaboratively setting shared basin-wide goals, identifying strategies to achieve those goals, cataloging investments in coastal wetlands, and reporting on relevant metrics to show results, the Assembly is working with Blue Accounting to deliver the data and the context needed to make informed decisions around coastal wetland management.

Coastal wetlands are lost to development, pollution, and invasive species – threats that continue to grow in the Great Lakes. As these culturally important and environmentally vital areas are removed, the remaining wetlands become fragmented from each other, weakening the overall system. Without a strong network of coastal wetlands, Great Lakes food webs suffer, shorelines are left unprotected, and the risk of poor water quality increases. Our solution moves us in the opposite direction, toward healthy coastal wetland systems.

Habitat

Habitat

Wetlands provide habitat for a diverse array of rare, threatened and endangered plants and animals, spawning and nursery habitat for fish, nesting and feeding areas for waterfowl, and migratory bird stopover sites.

Measuring Progress

The Assembly envisions a diverse system of Great Lakes coastal wetlands that meets the needs of native fish, wildlife and plant species while supporting our Great Lakes coastal communities and people who visit them.

To track the development of that vision, Blue Accounting measures progress using a variety of ecological metrics. These initial metrics were selected by the Assembly through a collaborative process with federal, state, tribal and non-governmental representatives. The metrics leverage the best available data and present an informative measurement of progress toward each goal. They are not intended to convey every facet of wetland health, but rather to provide the critical context to inform decision-making. The Assembly will evolve to include tracking progress towards socioeconomic goals and metrics.

Metrics by Goal

  • Health of aquatic insects and other invertebrates
  • Amphibian Health
  • Plant Community Health
  • Phragmites coverage in the wetland
  • Phragmites coverage around the wetland
  • Priority bird species population levels (under development)
  • Priority fish species population levels (under development)
  • Percent natural (or softened) shoreline
  • Coastal wetland area

How We Work

The Great Lakes Coastal Assembly, formerly the Coastal Conservation Working Group under the Upper Midwest and Great Lakes Landscape Conservation Cooperative, is the collaborative group behind Blue Accounting’s Coastal Wetlands issue. The Assembly provides a coordinated effort to:

  • Identify shared conservation goals and objectives for restoring and protecting coastal wetlands
  • Invest in data and knowledge to fill gaps, and tools to better inform decisions
  • Support and develop strategies that incentivize action and provide leadership towards attaining objectives

The Assembly provides their collective expertise to set goals, select metrics, identify strategies and work with key data providers to put together the information that is published by Blue Accounting. This coordination and collaboration allows us to present the best possible picture of this issue across the Great Lakes basin, as told by the people who are most involved.

Where We Work

From Saginaw Bay to Sandusky Bay in Western Lake Erie

The GLCA is currently piloting collaborative landscape conservation design and producing on-the-ground results for coastal wetlands from Saginaw Bay to Sandusky Bay in western Lake Erie. This area was selected as an initial focal area because the lake plains adjacent to the bays have low elevation and high coastal wetland restoration potential. They once supported expansive coastal wetlands but have been modified over time for agriculture and expanding urban areas.

Extensive data has been gathered in this pilot area, and new decision support tools have been developed. Guided by these tools, and with support from the Great Lakes Restoration Initiative, the Assembly can focus on-the-ground efforts to selected projects that lead to maximum, cost-effective impact. The Assembly is working to expand its efforts to the entire Great Lakes Basin and has recently added Canadian members. As the Assembly grows, the coastal wetlands information on Blue Accounting will grow with it.
