Our Workday.

Ohio River Bluffs is unarguably the most spectacular wildflower showcase in the state of Ohio. In spring, the cliffs facing the Ohio River just outside Manchester in Adams County are petal to petal flowers for a brief, heady 10-day floral explosion. There is literally nothing quite else like it, and we mean that literally because the floral display that once covered the Ohio River’s limestone cliffs for miles has winked out – either through tree clearing the cliffs for agriculture (later proven to be a misplaced ambition), or by the imbalanced invasion of  non-native plants – in most cases a combination of both. Ohio River Bluffs is the last of its kind, and now that we have bought this preserve, we have to continue to work hard to save it year after year, keeping the non-natives from pushing out the native plants. We work each spring pulling garlic mustard and in the fall removing woody invasives – primarily bush honeysuckle and multi-flora rose. We’ve come a long way in our last 8 years of work, enough to feel REALLY good about what we have done, but we have not yet managed to steward our entire acreage yet, so much work still faces us. This fall we will be working on the woodies, scanning the hillsides for bush honeysuckle, and working the mostly level ridgetop to remove multi-flora rose.

Leaders: Tim Pohlar & Debi Wolterman

Tim Pohlar is the Arc’s Land Stewardship and Volunteer Manager.  He is passionate about nature preservation and fell in love with the mission of the Arc from the day he first visited the website back in 2004, at that time it was only the Highlands Nature Sanctuary.  He started out as an intern, then worked as a seasonal staff for a few years after that, then was a full time staff, and lived throughout Sanctuary, from a tent by Talodon Pond, to an old farm house out on Rt 50, and many places in between.  In 2010, Tim met a wonderful lady, Miriam, and decided that fate was leading them into sustainable agriculture, so the two of them moved to La Crosse, WI, where they were married and had two little girls. They lived and worked on the family’s organic dairy farm for 8 years.  In this time, Tim gained a vast range of skills and views of the world that helped give him a much more rounded understanding of land management and preservation, and the intersections of farming and preservation.  Through a series of fateful events, Miriam and Tim, and their girls, Rose and Quinn, have returned to continue their work and passion with the Arc.  They are excited to further the mission of the Arc and work with the many wonderful people that come together to make it all possible!


 Debi Wolterman is an active conservation leader in the Cincinnati region and is known and loved by many. Her seemingly limitless energy and enthusiasm seems to radiate from her head of red hair, and she is definitely a lady of ACTION and WILL! Debi works all around SW Ohio as an indefatigable force for native plant preservation, and she can be seen pulling garlic mustard at a number of preserves in the region every April and May. We are fortunate she has adopted the Bluffs as one of her favorite preserves. Debi is active in the leadership of the Greater Cincinnati Chapter of the Wild Ones, an organization dedicated to encouraging the public to landscape with native plantings.



Lunch will be provided by the leaders, but if you are registering after April 1st, please consider packing a lunch just in case.

Ohio River Bluff’s Natural History

Ohio River Bluffs is a 62 acre tract on the Ohio River, just one mile west of Manchester in Adams County. The moderately young forest is a rich mixture of oaks, maples and hickories as well as yellow buckeyes and Kentucky Coffeetrees. The tract borders Highway 52 and runs from the base of the cliffs just above river, elevation, to the top of the bluffs. Both ridgetop and the calcareous steep bluffs are LOADED with flowers. Large colonies of bluebells cover much of the lower third of the elevations, and the remaining property is amazingly carpeted with dense stands of toadshade trillium, wild hyacinth and dwarf larkspur, as well as anemones, false Solomon’s seal, and Dutchman’s breeches. Ohio River Bluffs Preserve is open for each year’s Wildflower Pilgrimage and hundreds of people have enjoyed the natural floral spectacle over the years.

Physical Requirements

No invasive removal experience is necessary for this work day, but participants must be in good shape, possessing the kind of fitness that results from frequent moderate exercise and having sound balance and flexibility. Age, by itself, is not a limitation. All ages are welcome. The bluffs are very steep in some sections – not outright cliffs, but yes, definitely steep – and other areas only moderately sloped. Working any of the slopes can be a challenge. In the steepest zones, you are pulling garlic mustard with one hand and holding on to the nearest tree with the other to keep upright, or just laying on the ground for safety. Working on the Bluffs can be hard on one’s ankles because seldom are your feet aligned on level ground. Because the ground is rocky, a worker must be careful to avoid any falls whatsoever. When we work the bluffs, we take every step with deliberation and hold onto small trees for extra support when ever needed. For safety sake, we usually work facing up slope. When walking down slope we keep our attention only on supporting ourselves and not slipping. The physical challenges of the Ohio River Bluffs are part of the attraction of being a member of the Bluffs Blasters. We know this crew is not for everyone, but we also know when we risk the Bluffs that we are doing the “holy work” of protecting the preserve’s spectacular beauty for others. Our gift to the world!

What to Bring

Bring a bottle of drinking water, and, if you are coming to remove woody plants and do not have prescription glasses, bring a pair of sunglasses for eye protection. (Glasses are not necessary for garlic mustard plucking).  IT IS ESSENTIAL to wear snug but comfortably fitting footwear possessing a good tread, and a brimmed hat to keep the sun off your face. We haven’t tried cleats, but it might be a good idea to experiment with. If you have your own clippers, garden gloves with rubber coated protection, and light handsaws, bring them along. If you don’t, we can share our tools with you. Neither bugs nor poison ivy will be a problem at the Bluffs.

Address: Gilkison Hollow Road at US Rt. 52, Manchester, OH 45144

Ohio River Bluffs lies just west of the Ohio River town of Manchester on Rt. 52, the state route that parallels the southern border of Ohio on the Ohio River from Cincinnati to Portsmouth.

Directions from Bentonville to Ohio River Bluffs

Most trip plans to the Bluffs go through Bentonville, Ohio, 45105. Directions below will begin at this town.

At BENTONVILLE, turn LEFT, following the signs for State Route 136 South. Note that State Route 41 will separate from 136 and go off in another direction. Follow State Rt. 136 south approximately 5 miles until you reach MANCHESTER. When SR 126 deadends on 52, turn RIGHT on State Rt. 52. Follow State Route  52 WEST through the town of Manchester. As you leave the corporation city limits on the west side of town, set your odometer. It is one mile to our arranged parking destination. After leaving Manchester, look for a road to your right called Yates Road, and immediately after Yates, Gilkison Hollow Road. Continue on 52 past both these roads. The slope on the right is now the hill containing the Ohio River Bluffs Preserve. Look for your leader’s cars on your right roughly one half mile further on 52 from Gilkison Hollow Road. A wide shoulder offers ample parking off well back from the road. This is not a formal trailhead and will not be signed, but you should see red flags hanging off the trail’s entrance if you look closely. If you come to Owl Hollow Road on your right, you went a bit too far.
