The Everglades are dominated by sawgrass in water; this is the titular "River of Grass" popularized by Marjory Stoneman Douglas in 1947. This river contains a wide variety of plant and animal life. Early American environmentalist Gifford Pinchot said of the Everglades, "It is a region so different that it hardly seems to belong to the United States. It is full of the most vivid and most interesting life on land, in the air, and in the water. It is a land of strangeness, separate and apart from the common things we all know so well."[22]
