![]() | Dry TortugasNational Park - Florida |
Dry Tortugas National Park is about 68 miles (109 km) west of Key West in the Gulf of Mexico. The park preserves Fort Jefferson and the seven Dry Tortugas islands, the westernmost and most isolated of the Florida Keys. The archipelago's coral reefs are the least disturbed of the Florida Keys reefs.
The park is noted for abundant sea life, tropical bird breeding grounds, colorful coral reefs, and legends of shipwrecks and sunken treasures. The park's centerpiece is Fort Jefferson, a massive but unfinished coastal fortress. Fort Jefferson is the largest brick masonry structure in the Western Hemisphere, and is composed of more than 16 million bricks. Dry Tortugas is unique in its combination of a largely undisturbed tropical ecosystem with significant historic artifacts. The park is accessible only by seaplane or boat. Activities include snorkeling, picnicking, birdwatching, camping, scuba diving, saltwater fishing and kayaking.

Reconstruction
During Reconstruction, the Federal government pursued a program of political, social, and economic restructuring across the South-including an attempt to accord legal equality and political power to former slaves. Reconstruction became a struggle over the meaning of freedom, with former slaves, former slaveholders and Northerners adopting divergent definitions. Faced with increasing opposition by white Southerners and some Northerners, however, the government abandoned effor

Spiny Lobster Reserves
Spiny lobsters (Panulirus argus) are keystone predators that, by preying on other carnivorous invertebrates in the reef ecosystem, control populations and mediate competition among prey species. The removal of this species thus reduces the biodiversity and resilience of the entire system.

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.

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.
Veteran Story: Erin Rust
"This place is indescribable. There is an immense contrast between the incredibly delicate coral ecosystem and the monumental Fort Jefferson." A park ranger describes her transition from active duty military to veteran national park ranger.

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.

National Parks Defend America's Coast During World War II
Many national park sites joined the war effort in World War II by erecting Aircraft Warning, radio and radar stations. Some historic forts came to life with coastal defenses ready to defend the nation.

Data Manager Profile: Judd Patterson
Meet Judd Patterson, Data Manager for the South Florida Caribbean Network. As a data manager, helps wrangle all the information that we collect on the health of our park resources. Judd is excited about the stories data can tell through time, whether that's looking back at park records from over a hundred years ago, or making sure the science we do in our parks today become time capsules for future generations to learn about how things were back in 2021.

The Job is His, Not Yours
In the early 1950s, park wives continued to function as they had from the 1920s to the 1940s. The NPS still got Two For the Price of One, relying on women to keep monuments in the Southwest running, to give freely of their time and talents, to build and maintain park communities, and to boost morale among park staffs. With the creation of the Mission 66 Program to improve park facilities, the NPS found new ways to put some park wives to (unpaid) work.

Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks
Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.
