Maryland Celebrates Our Nation’s 250th Birthday!

Historic re-enactors in Revolutionary War uniforms

Maryland’s Story is America’s Story

This July 4, the United States celebrates the 250th anniversary of its independence. Maryland played a pivotal role in the Revolutionary War and the early years of nationhood. Fort Frederick State Park is one of many public lands in Maryland where visitors can see that history come to life.

Originally built as a stone fort during the French and Indian War, the site became a prisoner-of-war camp for British soldiers captured by American troops and militiamen at major battles in the war for independence. Watch the video about Fort Frederick’s events and history.

Visitors today can celebrate our history at Fort Frederick or one of numerous other historic sites on Maryland public lands.

The Story of America Can Be Followed on Maryland’s Trails

The primary mission of the Maryland Department of Natural Resources is to protect our natural environment, but as stewards of a half million acres of property, DNR is also custodian of our state’s rich history. Almost every Maryland State Park contains some historic feature, but some allow you to literally trace the footsteps of Maryland’s many contributions to the American story. Read more in Secretary Josh Kurtz’s column.

Liberty Tree Project: Living History Takes Root Across Maryland

Maryland’s original Liberty Tree, a tulip poplar located near what is now St. John’s College in Annapolis, became one of the state’s most significant historic landmarks. Citizens  gathered beneath its branches during the unrest surrounding the Stamp Act of 1765, making it a symbol of Maryland’s role in the nation’s founding.

This year, through the Maryland Liberty Tree Project, a genetically identical descendant of Maryland’s original Liberty Tree is being planted in each of the state’s 23 counties and Baltimore City. With most of the plantings now complete, Marylanders are invited to visit these trees and experience firsthand a living connection to the state’s past. Read more about the Liberty Tree Project.

Living Fossils and Symbols of Resilience: DNR Scientists Monitor Horseshoe Crabs After Population Recovery

Under the vibrant lights of the Ocean City boardwalk Ferris wheel and Slingshot ride, prehistoric animals scuttled onto the shore of a quiet beach by the thousands.

While the setting has changed, horseshoe crabs and their close relatives have been making this same journey to the world’s coastlines for hundreds of millions of years, through mass extinctions and the shift of continents, in what is considered the oldest wildlife migration on the planet. On spawning days that occur from May to July, these ancient arthropods return to beaches in Maryland and along the East Coast in search of mates.

“The horseshoe crabs are on,” Steve Doctor, a Maryland Department of Natural Resources fisheries biologist, said on a June spawning night. “It’s ‘Jurassic Park’ out there.” Read more.
