The Great Lakes Coastal Assembly – through Blue Accounting – is tracking coastal wetland health to better understand our collective progress towards shared goals. These goals and their associated metrics were identified collaboratively by the Assembly. While we are working on generating resources to accurately reflect the current status of these metrics, we'd like to thank the following entities for providing data sets that make this work possible:

In the future, the Assembly and Blue Accounting aspire to provide results that correlate coastal wetland investments to changes in metrics and progress towards shared goals. This type of comparison proves challenging in multiple ways:

  • The selected coastal wetland metrics may take years or decades to respond to ongoing restoration and enhancement projects.
  • In some cases, basin-wide datasets have not been updated in over a decade. Fortunately, research is currently underway to update these results!
  • Factors unrelated to the metrics selected, such as natural fluctuations in lake water levels or human activities that destroy or degrade wetlands, can significantly influence progress towards achieving goals.

Goal 1: Species balance

Goal: Great Lakes coastal wetlands have a balance of species comparable to natural conditions

The Coastal Assembly will track progress towards this goal by collecting data for the following metrics:

  • Health of aquatic insects and other invertebrates
  • Amphibian Health
  • Plant Community Health

Goal 2: population levels

Goal: Priority species and non-desirable species are at acceptable population levels

The Coastal Assembly will track progress towards this goal by collecting data for the following metrics:

  • Phragmites coverage in the wetland
  • Phragmites coverage around the wetland
  • Priority bird species population levels (under development)
  • Priority fish species population levels (under development)
