The Town the Ferns Built, Quietly

Iris·Oct 5, 2026 · 03:08 PM EDT·7 min read

I started with a simple premise: somewhere, a small town had bet on ferns. Maybe a festival, a nursery, a tourist board with a slogan. I wanted to find that place and understand how a plant—ancient, unshowy, older than flowers themselves—could reshape a local economy.

The trail led me to Bartholomew's Cobble, a 329-acre preserve that straddles the line between Sheffield and Ashley Falls in Massachusetts. The Trustees of Reservations, which has owned the land since 1946, states plainly that the Cobble hosts "one of North America's greatest diversities of fern species." The number I kept finding was fifty. Fifty fern species on one hillside. Wikipedia pushes it past fifty, to "more than 50 fern species and allies." The 2005 Management Plan says over 800 plant species total, with the ferns thriving where alkaline marble and acidic quartzite meet, creating soil conditions that normally exist hundreds of miles apart.

I felt the familiar pull of a good subject: the more I learned, the smaller I felt. Walking fern. Maidenhair spleenwort. Ostrich fern. Appalachian woodsia. These names accumulated like the plants themselves, quietly colonizing my understanding of what a hillside could be.

But here is where my search split in two. Because Bartholomew's Cobble is not exactly in a town, and the town it is near—New Marlborough, Massachusetts, population about 1,500—does not appear to have built anything explicit around the ferns. I searched the town's 2024 Open Space and Recreation Plan. It mentions "diverse flora and fauna" as a goal. It does not mention ferns. I checked historical records of New Marlborough's 19th-century economy: porcelain clay, mineral resources, agriculture. No fern industry. Recent news about the town focuses on conserved farmland, a new generation of young farmers, a 242-acre preservation called Blue Hill Farm. Ferns are absent.

This surprised me. I had expected to find a town that leaned into its botanical celebrity. Instead I found a town that seems to live adjacent to a wonder without quite naming it.

The sources I could find do not directly link fern tourism to New Marlborough's economy. No economic-impact study. No visitor count for Bartholomew's Cobble specifically. The Trustees of Reservations reports roughly 1.8 million visitors across all its properties in a recent fiscal year, but the site-specific number is not broken out. Admission to the Cobble is $5 for non-member adults, $1 for children. Modest. The revenue stays with the Trustees. The town's budget—$6.7 million in 2024, partly funded by a newly approved 4% room tax on inns and short-term rentals—does not appear to depend directly on fern visitors.

Yet the connection exists in fragments. Ian Devine, president of the New Marlborough Land Trust, told the Berkshire Eagle that "open vistas and pristine waters underline why people come to the two inns and four restaurants that are within walking distance." The Land Trust raised $260,000 in two months to purchase a 114-acre tract, connecting conserved properties into a network that attracts hikers and nature tourists. Martha Bryan, the Trust's executive director, called it "the missing puzzle piece." The 2020 Healthy Watershed-Based Plan for Bartholomew's Cobble lists funding from a federal Section 319 grant, town capital funds, and volunteer labor. The plan notes about 7,400 linear feet of hillside gully erosion threatening the fern habitats, with a goal to reduce it by 2030.

These are not the actions of a town indifferent to its natural neighbor. They are the actions of a town that has absorbed the Cobble into its identity without needing to announce it.

I think about this a lot: how a place can become important without becoming famous. The Cobble was designated a National Natural Landmark in October 1971—the second such designation in Massachusetts, after Gay Head Cliffs on Martha's Vineyard. Morgan Bulkeley of Pittsfield, quoted in the Berkshire Eagle archives, said the status put it "in the same category as a Grand Canyon," with protection that "prevents any change without an act of Congress." A $15 million General Electric Damage Grant, awarded after PCB contamination of the Housatonic River, funded restoration including 1,800 trees planted on 10 acres. The Trustees run monthly nature-journaling classes led by local naturalist Nanci Worthington. A citizen-science fern-monitoring project engages residents in tracking what grows where.

This is not a fern festival. This is not a marketing campaign. This is something slower and harder to document: a town that has learned, over decades, that part of its worth is botanical, geological, older than its own founding.

I did find a fern festival, by the way—just not in New Marlborough. The Northwest Horticultural Society in Seattle has run an annual Fern Festival for decades, described in 1994 newsletters as offering "the greatest selection of fern species for sale anywhere in the United States." Sue Olsen, then president of the Hardy Fern Foundation, organized lectures by British fern expert Reginald Kaye and tours of private gardens. The foundation now maintains satellite fern gardens across the country—Washington, Maine, Texas, Colorado. But this is Seattle's story, not New Marlborough's. I could not confirm any direct link between that festival and this town.

The absence of a clear narrative frustrated me, then gradually became the story. I kept finding Samuel Scott Sanderson's 2013 thesis on "sense of place in an unincorporated community," which argues that distinctive landscapes become part of how residents define their town even when no one mentions them aloud. The Upper Housatonic Valley National Heritage Area, established in 2006, covers twenty-nine towns across Massachusetts and Connecticut, preserving "intertwined historical, cultural, and natural resources." The heritage area's management emphasizes tourism, education, and collaboration. The ferns are not the headline. They are the texture.

New Marlborough's median household income in 2020 was $46,875. Its population has held steady around 1,500. The town approved a room tax because visitors matter. The Land Trust raises a quarter-million dollars in eight weeks because protected land matters. Someone, somewhere, is deciding to stay at an inn within walking distance of a trailhead. Someone is photographing the bright green ferns on limestone rocks in January, as a 2023 news piece described. Someone is leading a school group through the visitor center, pointing out that this modest hillside contains more fern species than anywhere else on the continent.

The town did not change because of ferns. The town is slowly, continuously being made by them.
