The Boston Harbor Islands National Recreation Area is situated among the islands of Boston Harbor of Boston, Massachusetts. The area is made up of a collection of islands, together with a former island and a peninsula, many of which are open for public recreation and some of which are very small and best suited for wildlife.
Attractions include hiking trails, beaches, the Civil War-era Fort Warren on Georges Island and Boston Light on Little Brewster Island, the oldest lighthouse in the United States. Georges Island and Spectacle Island are served seasonally by ferries to and from Boston and Quincy, connecting on weekends and summer weekdays with a shuttle boat to several other islands, Hull, and Hingham.

Citizen Science in the Digital Age
With well over 100 citizen-science based apps now available for smartphones, there is no lack of opportunity for people of all ages and affectations to significantly add to the collective knowledge base about many aspects of the natural world. The phrase “there is an app for that” has perhaps never been more true for natural resource monitoring.

Designing the Parks: Learning in Action
The Designing the Parks program is not your typical internship. Each year since 2013, this program at the Olmsted Center for Landscape Preservation has introduced a cohort of college students and recent graduates to NPS design and planning professions through projects related to cultural landscape stewardship. In the internships, made possible by partner organizations, participants focus on an in-depth project that directly engages with a national park unit.

Preserving Places of Captivity: Civil War Military Prisons in the National Parks
During the Civil War, over 400,000 Union and Confederate soldiers were held prisoner at more than 150 diff erent prison sites. Approximately 56,000 of these died in captivity. Although Andersonville is the most famous Civil War prison, it is only one of many Civil War military prisons that are preserved by the National Park Service.
Disability History: The NPS and Accessibility
The National Park Service strives to make its parks, monuments, and historic sites available to all. Programs, services, and products, such as Braille alternatives of print material, sign language interpretation of tours, accessible camping sites and trails, ramps and elevators make parks more accessible. These are essential to allowing the public to fully enjoy NPS resources.

Third System of Coastal Forts
How should a country protect its borders? The United States had to consider this question when the War of 1812 ended in 1815. One year later, the federal government believed it had an answer. The nation created a broad national defense strategy that included a new generation of waterfront defenses called the Third System of Coastal Fortifications.

Seacoast Ordnance
Cannon manufactured for use in Third System forts are called seacoast ordnance. These were some of the largest and heaviest cannon available at the time. Cannon at forts Pickens, McRee, Barrancas, Massachusetts, and Advanced Redoubt fell into three categories: guns, howitzers, and mortars. Each had a specific purpose.
Rocky Intertidal Research in the Boston Harbor Islands National Recreation Area
Along coastlines, where the land meets the sea, is an area known as the intertidal zone -- the region between the lowest low tide and the highest high tide. How do relationships between organisms affect where different species are found, and how important are local environmental conditions in controlling the distributions of species? Drs. Jane Lubchenco and Bruce Menge, two marine ecologists, set out to answer these questions.

Series: Disability History: An Overview
Disability History: An Overview brings attention to some of the many disability stories interwoven across the National Park Service’s 400+ units and its programs. “Disability stories” refer to the array of experiences by, from, and about people with disabilities represented across our nation. People with disabilities are the largest minority in the United States, but their stories often remain untold.

The Precambrian
The Precambrian was the "Age of Early Life." During the Precambrian, continents formed and our modern atmosphere developed, while early life evolved and flourished. Soft-bodied creatures like worms and jellyfish lived in the world's oceans, but the land remained barren. Common Precambrian fossils include stromatolites and similar structures, which are traces of mats of algae-like microorganisms, and microfossils of other microorganisms.

Can you name five bees in your park? Ten? Twenty? Will they all be there 50 years from now? We know that pollinators are key to maintaining healthy ecosystems—from managed almond orchards to wild mountain meadows. We have heard about dramatic population declines of the agricultural workhorse, the honey bee.

Design and Armament of Fort Warren
Following the War of 1812, Georges Island was selected as a site to build a coastal fortification to protect Boston and its harbor. Construction began in the early 1830s and took almost twenty years to complete. The remnants of construction remained when soldiers arrived and began arming Fort Warren shortly after the start of the US Civil War in 1861.

Flying Santa
Captain William Wincapaw started a nearly hundred-year tradition when he loaded his plane with dozens of packages containing items such as newspapers, candy, and coffee, and dropped them off to various lighthouse stations along the coast of Maine on December 25, 1929. Through this well-received gesture to show his appreciation for the lighthouse keepers he frequently worked with, Wincapaw became known as the first “Flying Santa.”

The Big Dig and Spectacle Island's Environmental Restoration
When construction on the Central Artery/Tunnel Project (known as “The Big Dig”), began in 1991, the city of Boston undertook one of the largest infrastructure projects in its history. The project had two main goals: to alleviate traffic on an overburdened, elevated highway that had begun deteriorating, and to extend I-90 from south of downtown Boston. To achieve these goals, engineers planned to create an underground highway mostly consisting of tunnels.

Island Histories that Inspired "Shutter Island"
Inspired by the history of the Boston Harbor Islands, Bostonian Dennis Lehane published his book Shutter Island in 2003. In this thriller, Lehane created a fictitious hospital island with nefarious happenings. Though the later film used Peddocks Island as the backdrop, Lehane’s true inspiration likely comes from other islands that have long histories in institutions and social services, such as Rainsford Island and Long Island.

How Pollinator Inventories Can Inform Park Management Decisions
Pollinators play a crucial role in national park ecosystems and beyond. In the national parks, species inventories help managers know which pollinators are present, and in what abundance, to better understand the state of park ecosystems and make decisions about how to manage them. From 2024 to 2026, 17 parks across the country will be surveyed for bees and butterflies.

The Great Brewster Island Adventure
On July 15, 1891, four intrepid women from Lowell, Massachusetts, set sail to Great Brewster Island on an adventure they would remember for their lifetime.
