When European settlers arrived in what is now New England, they set to work with axes and ambition, clearing forests at a staggering pace to make way for farms. By the mid-1800s, Massachusetts had lost an estimated 90 percent of its tree cover. Neighboring states weren't far behind — New England as a whole had been stripped of roughly 80 percent of its forests.
Today, those numbers tell a completely different story. Massachusetts is estimated to be 60 percent forested. And that transformation hasn't just been remarkable: scientists say it is, without parallel, the greatest forest recovery in the history of the world.
"The regrowth of forest in the northeast U.S., particularly New England, is the greatest forest recovery in the history of the world," said Bill Moomaw, a distinguished visiting scientist at the Woodwell Climate Research Center, speaking this week on PRX public radio. "And it all happened because of what I call benign neglect. It was not a plan — it was just abandonment of agricultural lands. It's remarkable what has happened in the last hundred years."
Nature's Quiet Comeback
The story behind this recovery is a fascinating collision of economics, ecology, and time. In the mid-1800s, as industrialization took hold and settlers moved westward to more fertile land, New England farms were simply abandoned. No one planted a single tree. No conservation plan was set in motion. The forests came back entirely on their own.
Red maple, oak, birch, and eastern white pine slowly reclaimed old fields and pastures, rebuilding ecosystems that had supported Indigenous peoples for thousands of years before European colonization. Deer, wild turkey, black bear, and fisher cats returned along with the canopy. Biodiversity that had been erased over generations quietly reassembled itself.
What makes this recovery scientifically significant is its scale and speed. Within roughly 150 years — barely a blip in ecological time — a region once nearly barren of trees transformed into one of the most densely forested areas in the United States.
Far More Than Scenery
The benefits of New England's forest recovery reach well beyond the beauty of fall foliage. Trees are massive carbon sinks, pulling carbon dioxide from the atmosphere and locking it into wood and soil. A 60-percent forested Massachusetts represents an enormous reservoir of stored carbon — carbon that would otherwise be contributing to climate change.
The forests also support extraordinary biodiversity. From migratory songbirds to woodland salamanders to native pollinators, the returning canopy has created habitat corridors connecting fragmented ecosystems across six states. Water quality in the region has improved dramatically as tree roots filter runoff, stabilize stream banks, and regulate water flow into rivers and aquifers.
A Blueprint for the Future
Moomaw's remarks carried particular weight because they came as the United States celebrated its 250th birthday this July — a moment to take stock of both the ecological damage and the remarkable healing that have unfolded over two and a half centuries.
For conservationists and climate scientists, the New England story offers a powerful argument: sometimes the most effective thing humans can do for nature is step back and let it heal. This "proforestation" approach — protecting existing mature forests from logging and development — is increasingly recognized as one of the most cost-effective climate solutions available.
Other regions, from the Atlantic Forest in Brazil to the highlands of Ethiopia, are watching New England's natural experiment with intense interest. If a region once stripped nearly bare can recover to 60 percent forest cover in a century and a half, the ecological possibilities elsewhere are genuinely extraordinary.
The forests that define New England today — the blazing reds and golds of fall, the towering white pines, the dark hemlock hollows — were nearly gone not so long ago. That they came back is one of the most hopeful environmental stories of our era.
