Data and Major Findings

Data collected by the Coastal Wetland Monitoring Program (CWMP) can be used to determine the health of Great Lakes coastal wetlands and help managers make better-informed decisions. Each of the five taxonomic groups sampled and surveyed are summarized below.

Amphibians

The spatial distribution of amphibian species surveyed from 2011 - 2015 across the Great Lakes basin is represented in the map below (Figure 1).

The map shows the distribution of amphibian species across the Great Lakes basin surveyed from 2011 - 2015 (Figure 1).

There were 711 coastal wetland sites sampled, 486 of those had either two or three amphibian species present (Figure 2).

Figure 3 represents the results of wetland amphibian surveys from 2011 - 2015 for five geographic regions: Green Bay, the Lake Huron-Lake Erie corridor (HEC), Saginaw Bay, southwest Superior (SW Superior), and the western Lake Erie basin (WLEB). Amphibian data collected had no listed or invasive species present in any of the regions.
