GOAL: / METRIC: Coastal wetland acreage

This metric relies on work of the pilot Coastal Wetlands issue and is presented here only to test functions within the new website.


Diverse & Resilient Wetlands: Acreage of Projects

View Full Screen Map

This metric is a snapshot of the acreage (area) of coastal wetlands that are currently in projects that will protect, restore or enhance wetlands, visible by state, lake, and other geographic filters.


At this time we are measuring progress against the annual targets published by the Great Lakes Restoration Initiative (GLRI).  81% of the 2017 GRLI target for acreage was reached.


Objective: reach Great Lakes Restoration Initiative (GLRI) action plan II and III annual coastal wetland acreage target values Metric: total coastal wetland acreage protected, enhanced, or restored by GLRI projects. Our objective addresses our goal because Great Lakes coastal wetlands are most self-sustaining and are better able to provide benefits to fish, wildlife, and people when wetland extent and diversity are at or close to their natural range of variability across a diversity of regions.



Percent of Great Lakes Coastal Wetlands protected, by state or province.  By Stephanie Hickel, The Nature Conservancy

Percent of Coastal Wetlands that are protected for each state or province in the Great Lakes Basin (except Québec, due to data limitations).  The percentages vary from a high of 91% to a low of 4%, but the number of coastal wetland acres also varies widely.  The five states with the highest total wetland acreage have protected between 37% and 54% of coastal wetlands, while Ontario has protected 17%.
