![]() | Boston Harbor IslandsNational Recreation Area - Massachusetts |
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.

Species Spotlight - Crazy Snakeworm
Because of the scouring action of the ice age, earthworms are not native to the northeast. One species in particular, the crazy snake worm, has the potential to greatly alter the natural forest ecosystems in our region.

Red, Green and Blue: Identifying Philadelphia’s LGBTQ+ Historic Places
The National Park Service is committed to preserving and interpreting the history of all Americans in all of its diversity and complexity. However, even some of the nation’s most important historic sites have found their history leveled by the wrecking ball. How, then, can communities preserve sites that witnessed the history of minority groups, such as lesbian, gay, bisexual and transgender and queer persons (LGBTQ+)* or others struggling for equality?

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.

Safe Harbor: The Maritime Underground Railroad in Boston
During the years preceding the American Civil War, Boston served as one of the most important stops on the Underground Railroad. Many of the freedom seekers escaping slavery came to Boston by stowing away on ships from southern ports.

Series: Disability History
The Disability History series 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.

Pollinators in peril? A multipark approach to evaluating bee communities in habitats vulnerable to effects from climate change
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. Yet what do we really know about the remarkable diversity and resilience of native bees in our national parks?
