A number of conservation areas have been named for Carson as well. Between 1964 and 1990, 650 acres (263 ha) near Brookeville in Montgomery County, Maryland were acquired and set aside as the Rachel Carson Conservation Park, administered by the Maryland-National Capital Park and Planning Commission. In 1969, the Coastal Maine National Wildlife Refuge became the Rachel Carson National Wildlife Refuge; expansions will bring the size of the refuge to about 9,125 acres (3,693 ha). In 1985, North Carolina renamed one of its estuarine reserves in honor of Carson, in Beaufort.
