In 1956, the United States established a national park on one of the Virgin Islands. The United Nations named the national park a Biosphere Reserve in 1976. To help manage the park as a Biosphere Reserve, the National Park Service wanted to understand how fast the trees were growing. To do this, they invited the Forest Service to do a study of the trees in the Cinnamon Bay watershed, one of the areas within the Biosphere Reserve.
