Target Species

Target species are potential County Records - species not yet documented in the county. 'Local Obs' is Local Observations and indicates the number of times that the species has been observed in adjacent counties since 2000, and '# of Counties' is the number of adjacent counties in which those recent observations took place. Zero local observations or recent counties means the existing records are historical. 'Peak Active' is a relative description of when the species has been known to fly.

Located in the Allegheny Plateau, the terminal moraine divides Holmes County in half, reaching its maximum southern extent in the Killbuck Valley, just south of the county seat of Millersburg.  The lower half of the relatively small Lake Fork Mohican River (302.1 cu ft/second) flows through the northwestern corner of the county, intersecting the Mohican River, which flows several miles through the southeast corner of the county.  The most significant waterway in the county is the Killbuck Creek, which cuts the county in half north to south.  The Doughty Creek, flowing SE from Berlin and joining the Killbuck several miles south of the Holmes Coshocton line is the largest waterway in the eastern half of the county (no public access other than bridges).    The Killbuck Valley between Wooster (Wayne County) and Layland (just south of the Coshocton County line) benefits from silt, sand, and gravel deposited by glacial outwash.  Originally a huge marshland, much of it was drained in the late 19th and early 20th century, but continued flooding has discouraged farming, rail, and roads, and after WWII, much of this area has been reverting to marshland.  The glaciated northern half of the county is dominated by small family farms, many of them Amish, while much of the southern half, in the Unglaciated Allegheny Plateau, is wooded.  (see Muskingum River Watershed)

Places to Visit

Holmes County has relatively little publicly accessible land, virtually all of which is in the Killbuck Valley. 

  • Most of the 5,700 acre Killbuck Marsh Wildlife Area is located in Wayne County, but the property extends all the way south to Holmesville (3.8 miles).  The best access is just south of the county line, east of SR 83, on CR 1, which provides access to the Killbuck Creek, a small pond, and marshland along both sides of CR 1. Be aware that the area between CR 1 and Force Road (Wayne County) is a wildlife Refuge area and is closed to the public. The ODNR does provide some parking areas, but otherwise, the Holmes section of the Wildlife Area is totally unimproved, with no maintained trails and no facilities.

  • The Killbuck Watershed Land Trust owns multiple pieces of Holmes county property starting just north of Killbuck, and extending through the Killbuck Valley to just past the Coshocton County line. All of the land north of SR62 is open to public access.  Trails and parking improvement are rudimentary, but improvements are underway.  This land is not well documented on their web site, and a property map application like onX Hunt is recommended

    • Baker Swamp is located just north of the Holmes County Trail.  Park at the trailhead parking lot just east of Killbuck on County 622.  All of the land north of the trail, starting just west of the power substation and east to Township 91 belongs to the trust.  Walk east on the paved trail to TR 91 to access Killbuck Creek (see interactive map above).

    • Turtle Pond is a relatively new 80 acre acquisition immediately east of the village of Killbuck, between Killbuck Creek, County 621, and SR 520.  A small parking area on 621 just west of the bridge provides access to a 600 yard gravel walking path between the river and marsh. A second parking spot at the intersection of Holmes 621 and SR 520 (10114 OH-520, Killbuck, OH 44637) provides access to a wooded hillside and the NW corner of the wetland (see interactive map above).

    • A grant for the restoration of the newly acquired 150 acre Crane Swamp property on the Holmes/Coshocton line has been approved. This area is scheduled to be opened to the public in late 2025.

  • Legacy Point Park, a former landfill that includes multiple ponds, is scheduled to open in 2025.

  • Mohican State Scenic River Designation Study. This is a 55 page ODNR analysis of the Clear Fork/Mohican River created in 2006 leading up to its inclusion into Ohio’s Scenic Rivers System.  It provides an overview of the human and natural histories of the Mohican River and its tributary creeks, and includes detailed maps. There is no public access to the Mohican in Holmes County, but a number of small bridges provide some visibility into the Lake Fork Mohican tributary.

  • Mohican River Water Trail Guide from ODNR.
