The islands have great historical significance in a number of ways. Archeological sites on 21 of the islands have been placed on the National Register of Historic Places and all the islands are considered likely to have significant sites. Evidence indicates that Native American peoples lived on the islands as early as 1000BC and perhaps before they separated from the mainland sometime in the 2000 years previous to that. The highly alkaline shell-fragmented soils which preserve artifacts better than typical New England soils, and the relatively low-intensity use by Euro-Americans, make the islands an archeological treasure.
The islands have undergone many various uses over the years: agriculture, cemetery, fishing colony, fortifications, hospital, hotel or resort, industrial, poorhouse, prison, prisoner-of-war camp, quarantine, sewage treatment, lighthouses, and dumps.
Deer Island has particular significance to Native Americans as a place of imprisonment and interment during King Philip's War in the 1670s. Contemporary Native Americans return each October to commemorate their ancestors' suffering in this tragic slaughter. Indications are that 1000 or more American Indians were forced onto Deer and other of the islands, often to die of starvation. Later Deer Island also served as a quarantine hospital in 1847 to treat the many sick, impoverished Irish immigrants fleeing the potato famine.
In 1970 the Commonwealth of Massachusetts began acquiring islands for the benefit of the public. In 1985 Boston Harbor was named the most polluted harbor in the nation. After investment of four billion dollars and extensive wastewater treatment efforts by the Massachusetts Water Resources Authority, improved water quality contributed to widespread support for establishing a national park area.
The Boston Harbor Islands National Recreation Area was established by act of Congress in 1996. The Partnership which governs it is made up of thirteen members appointed by the Secretary of the Interior to represent various Federal, State, City of Boston, and non-profit interests. The Partnership subsequently adopted the name "Boston Harbor Islands, a national park area" in response to Native Americans' objections to the term "recreation" being used for an area they consider sacred.
- The land area changes from 3100 acres to 1600 acres as the tide rises from low to high. The typical island, and even the peninsulas, consist of drumlins (rounded hills of till that form under glaciers). Some of the smaller islands are based on rocky outcroppings. The larger islands have a variety of landscapes—deciduous trees and thickets of bushes, salt marshes, bluffs, cliffs and, of course, beaches and waterscapes, including lighthouses.
Flora and fauna
Many of the islands have trees, with some having been planted for shade in recent years. Native plants such as bayberry and beach plum are abundant. Decorative flowers are in raised plantings so as not to disturb possible archeological sites. Many marine and migrating birds are found on the islands. Lovell Island has a large population of European hares put here in the 1940s and 1950s. Gallops Island also has a large population of rabbits.
