Preserving a Wilderness for Biodiversity. Forest fragmentation and destruction are two of the leading causes of biodiversity decline across America’s Great Eastern Hardwood Forest. The larger an intact forest community, the better it can nurture its primeval complex of plants and animals. Large, old forests equate to high biodiversity. The Arc’s primary purpose for founding Tobacco Barn Hollow in 2007 was to provide homes for some of Ohio’s most vulnerable wildlife species. Today, 18 years later, we wish to expand it in size for the very same reasons.

Herp “Central.” Tobacco Barn Hollow has the greatest diversity of amphibians and reptiles of any preserve in the Arc of Appalachia properties. Tobacco Barn Hollow is not only a documented refuge for timber rattlesnakes, but it also provides a safe harbor for many other reptiles as well, including gray rat snakes, rough green snakes, black racers, and ring-necked snakes, to name a few. Timber rattlesnakes have been intensely studied at Tobacco Barn Hollow Preserve over the years by expert field researchers. By marking individuals with small tracking devices and then laboriously following them around all summer, a remarkable amount of information has been gleaned about their seasonal behaviors. We’ve learned how far a snake will cover ground in a season, where it hibernates, and what perils present themselves throughout the year. Several specimens of timber rattlesnakes have been found crossing the very lands that we are currently pursuing for acquisition.

Tobacco Barn Hollow is equally rich in amphibian diversity. Vernal pools teem with life in early spring at a time when mole salamanders, newts, and wood frogs play out their ancient breeding rituals. The rarest amphibian discovery that has been made in the preserve has been the state-endangered eastern spadefoot toad. Multiple records of these extremely rare animals have been found on existing preserve lands, but where these animals are actually breeding remains a mystery.

Botanical Hotspot. On one of the parcels, which has only recently been added to the campaign, Arc staff members were delighted to discover the densest wildflower display we have ever witnessed on soils derived from sandstone and shale bedrocks. Dense displays of celandine poppy, sweet William phlox, perfoliate bellwort, Jack-in-the-pulpit, green dragon, long-spurred violet, and large-flowered trillium dominate the dense carpets of flowers. In early summer, stunning towers of Canada lilies unfurl into bloom. Tobacco Barn Hollow’s floral diversity and bounty rival the flower showcases of the Arc’s karst-country preserves, which is really saying something!

We Speak for the Birds! Preserving habitat for breeding birds on both ends of their arc of migration is now an urgent necessity if we are not to witness the tragedy of a rapidly approaching Silent Spring. The population of North American birds has dropped nearly 30% since 1970,which equates to a staggering loss of three billion birds. Because the word “billion” is beyond our comprehension, considering the losses of specific species helps drive this point home. Since 1970, we have lost 168 million dark-eyed juncos, 93 million white-throated sparrows, and 139 million meadowlarks. Roughly one out of every four birds that shared our world back in 1970 has vanished into thin air. These missing birds are the “canaries in the coal mine” for planet Earth. Their deaths demonstrate that the life force of our planet’s ancient, natural communities - including our Eastern Forest - is flickering out as it loses its ability to sustain abundance and biodiversity.

All of the bird migrants that winter in the tropics and nest in the deep forests of the Eastern United States - from scarlet tanagers to hooded warblers and wood thrushes - have significantly better breeding success when provided with large, intact blocks of forests. This is where their insect food reserves are the most secure, and where the threat of parasitic cowbirds laying eggs in their nests is minimized. Thus, all of our forest birds benefit from the Tobacco Barn Hollow project - our vireos, tanagers, gnatcatchers, and warblers. But the birds that will benefit the most are those that don’t just prefer large blocks of forests to reproduce successfully, they require them. Signature deep forest birds include worm-eating warblers, ovenbirds, cerulean warblers, and Kentucky warblers. All of these species can be found in high numbers in the forests of Tobacco Barn Hollow, and they will especially benefit from our planned forest protection in the region.

Funding Status for the Property.

Fantastic Grant News. In November of 2025, the Arc was awarded its second grant submission to the Clean Ohio program for the expansion of Tobacco Barn Hollow, shooting up our progress thermometer. We are delighted to report that, thanks to your generous donations and to the awards of two phases of Clean Ohio grants, the $2,768,730 campaign is now only $125,000 away from the finish line and 99% complete!
