Maine Ecological Reserves Program
Name: Maine Ecological Reserves Program
Description: The Maine Ecological Reserves Program was established to monitor properties within the ecological reserve system in the State of Maine. These lands are managed by the Bureau of Parks and Public Lands, and the Maine Natural Areas Program oversees the long-term ecological monitoring plan. The Maine Chapter of the Nature Conservancy has established monitoring plots on ecological reserves it has designated on its properties as well. As of 2013, Maine has designated more than 90,000 acres of Ecological Reserves on 17 public land units.
