Spring Valley Wildlife Area
Wayne Township, Warren County, Ohio
Marker Inscription
Nearly 90% of Ohio’s wetlands are gone, but some remain in glaciated northern areas and near Lake Erie. Spring Valley Wildlife Area, once a fur farm, now hosts over 230 bird species and showcases diverse wetland, brushland, and forest wildlife.

The Story
When European settlers arrived, Ohio was nearly a fifth wetland — but two centuries of draining and tiling for farmland erased close to 90% of it, leaving only remnants in the glaciated north and along Lake Erie. This tract in the Little Miami valley carries an odd chapter of that story: it once operated as a fur farm before being reclaimed as protected habitat. Today its restored mosaic of marsh, brushland, and forest draws more than 230 bird species, a small standing rebuke to all that was lost.
Why it matters
It marks the larger American reckoning with a landscape we transformed almost beyond recognition — and the 20th-century conservation impulse that began buying back and protecting the wild places earlier generations drained away.
The story behind this marker
AI contextThe era
When European settlers first spread across Ohio, they found a land far wetter than the farm country we picture today. Nearly a fifth of the state was wetland — marsh, swamp, and seasonally flooded forest — much of it left behind by the great glaciers that had ground across the northern reaches of the region in the deep past.
To farmers, that water was an obstacle, not a treasure. Over roughly two centuries, settlers and their descendants drained, ditched, and tiled the wetlands to turn them into cropland, and the transformation was staggering: close to ninety percent of Ohio's original wetlands were erased. What survived clung mostly to the glaciated north and the low ground near Lake Erie.
By the twentieth century, the tide of thinking had begun to turn. A conservation impulse took hold across America, and states started buying back and protecting the very wet places earlier generations had worked so hard to drain — recognizing, almost too late, how much life those soggy acres held.
People & events
This particular tract in the Little Miami valley carries an unusual twist in that larger story. Before it became protected habitat, it operated as a fur farm — a place where animals were raised for their pelts. It is an odd, very human chapter: land put to a commercial use, then reclaimed for wildlife.
Today the site is managed as the Spring Valley Wildlife Area, and the transformation is complete. Its restored patchwork of marsh, brushland, and forest now supports an astonishing range of life, with more than 230 species of birds recorded moving through its waters and thickets over the seasons.
That number is the quiet drama of the place. Each of those species is a small vote in favor of what wetlands do when they are allowed to be wetlands again — a living answer to all that was lost when the draining was at its height.
Its place in the American story
The marker points past its own boundaries to a national reckoning. All across America, settlers remade the landscape with astonishing speed, treating swamps and marshes as wasteland to be conquered. Only later did the country begin to grasp the cost: wetlands filter water, buffer floods, and cradle a density of birds, fish, and plants that few other habitats can match.
Spring Valley is one small monument to the twentieth-century course correction — the movement to set aside, restore, and defend the wild places that had nearly vanished. Multiply this one tract by thousands of refuges and wildlife areas nationwide, and you have the story of how America learned to value what it had almost drained away.
The fur-farm-to-refuge arc makes the point vivid. Land that people once bent entirely to their own use can, with intention and patience, be handed back to the wild — and the wild will return to fill it.
If you visit
Bring binoculars. With more than 230 bird species on the record here, Spring Valley rewards the patient watcher, and the mix of open marsh, brushy edges, and woodland means the cast of characters changes as you move and as the seasons turn.
Walk slowly and let your ears do some of the work — a wetland announces itself in sound long before you see much. Early morning is classic birding time, and the boundary zones where marsh meets brush meets forest are where the variety tends to concentrate.
As you go, hold the marker's larger message in mind. You are standing in a rare survivor — a fragment of the watery Ohio that once covered a fifth of the state. It fits naturally into a slow, nature-minded road trip through the Little Miami country, a place to stretch your legs and remember what this landscape used to be.

George Barrett Cement House
Spring Valley, OH
In 1853, after fire claimed his home, an Ohio farmer named George Barrett rebuilt not with the usual brick or timber but with cement — following a construction method he'd picked up from his own reading. It was a resourceful, self-taught choice in an era when concrete building was still a novelty in rural America, and it proved both cheaper and quicker than conventional masonry. The house he raised in Greene County's Spring Valley stood durable enough that, more than a century later in 1986, it earned a place on the National Register of Historic Places.
Stevenson Road Covered Bridge
Xenia Township, OH
When this bridge went up in 1877, the covered wooden span was still the workhorse of rural American roads, its roof and siding shielding the timber trusses from the weather that would otherwise rot them within a decade. Its builder, the Smith Bridge Company of Toledo, Ohio, was founded by Robert W. Smith, who patented a distinctive truss design that let his firm ship prefabricated bridges by rail across the country. The Stevenson Road bridge carried Greene County traffic for well over a century before finally retiring in 2003, and it survives today as one of the comparatively few Smith truss spans still standing.
McCook Field
Dayton, OH
In the years around World War I, the U.S. Army turned a stretch of Dayton floodplain into one of the nation's first centers for aviation research, fittingly located in the hometown of the Wright brothers. Through the late 1910s and 1920s, engineers here pushed the young science of flight forward, testing new aircraft, engines, and equipment and chasing altitude and speed records at a time when airplanes were still a novelty. As the work outgrew the cramped, flood-prone site, it moved to a larger field nearby that would eventually become Wright-Patterson Air Force Base.
Deerfield-South Lebanon
South Lebanon, OH
In the years just after the Revolution, pioneers pushed into the Ohio country, and the settlement that became Deerfield took root around 1795 in the Little Miami valley of what is now Warren County. Benjamin Stites laid out the town in 1802, and among its first residents were veterans of both the Revolution and the War of 1812, men who had traded muskets for plows on the young republic's frontier. As the community matured it folded into Union Township in 1815, took the name South Lebanon in 1871, and grew an industrial side — powder works and food businesses that gave the village a working economy well into the industrial age.
