The GLREC recognizes the importance of the Great Lakes as the world's largest surface freshwater resource and their critical contributions to the environment, communities, and economies of the region. Great Lakes literacy is an understanding of the Great Lake’s essential principles and fundamental concepts about the characteristics, functioning, and value of the Great Lakes, their watersheds and tributaries. A Great Lakes literate person can communicate accurately about the Great Lakes’ influence on systems and people in and beyond their watershed and is able to make informed and responsible decisions regarding the Great Lakes and the resources of their watershed (Center for Great Lakes Literacy - CGLL). The Centers for Ocean Sciences Education Excellence (COSEE) Great Lakes, supported by the U.S. National Science Foundation and the National Oceanic and Atmospheric Administration (NOAA), developed the for the to serve as a guide for education of students and the public. Not all GLREC partner parks lie on the coasts of the Great Lakes. Still, the National Park Service and the GLREC promote these principles through education, communications and research in Great Lake’s coastal national parks.
