Herrick Fen Preserve is one of the last remaining boreal fens in Ohio. It provides habitat for over two dozen state-listed species.



Please note: due to a washout of the access road, Herrick Fen Preserve is currently closed for visitation until further notice.

Herrick Fen Preserve features unique geologic, hydrologic, biologic and physical features that resulted from the retreat of glaciers during the last ice age, some 12,000-14,000 years ago.

The preserve hosts two special fen communities, owing their presence to an impermeable silt and clay layer covered with glacial gravel that allows for the rise of cold, calcium- and magnesium-rich springs. The tamarack fen is the only native conifer in Ohio that sheds its needles each year, and the preserve boasts one of the few reproducing populations of it in the state. The cinquefoil-sedge fen contains an extensive population of bayberry, a state endangered plant found in only three locations in Ohio.

All told, the preserve provides habitat for over two dozen state-listed species. The initial preserve tract was purchased by Dr. J. Arthur Herrick in 1969 and now comprises some 140 acres. It is jointly owned by The Nature Conservancy and Kent State University, and managed by The Nature Conservancy as a dedicated state nature preserve.




J. Arthur Herrick Fen Preserve is one of the last remaining boreal fens in Ohio. While there, you can see tamarack trees, the only native conifer trees in Ohio. Activities include hiking, bird and wildlife watching, and nature photography.

  • Visitors should keep their eyes open for the more than two dozen state-listed plant species the preserve protects. Among them are:

    • Five types of sedges, including Broad-winged and Bebb's
    • Reproducing populations tamarack
    • Crinkled hairgrass
    • Round-leaved sundew
    • Bayberry
    • Small fringed gentian
    • Tall St. John's-wort
    • Butternut
    • American water-pennywort
    • Bunchflower
    • Autumn willow
    • Ohio goldenrod
  • The preserve features an easy 1-mile trail to and from the parking lot.

    Visitors will enjoy the preserve’s boardwalk, which showcases some of the preserve’s most distinct features, such as seeps and fen plants—including Bayberry and the round-leaved sundew, a tiny carnivorous plant that inconspicuously grows on sphagnum moss.

    The boardwalk, among other things at Herrick Fen, has been renovated, allowing for better public access. In order to protect the sensitive species, and for your safety, please stay on the boardwalk and nature trails.

Current Conservation Work

Threats to the preserve include urban encroachment, siltation, and invasive non-native plant species such as buckthorn, cattail and reed canarygrass. Extensive and prolonged fluctuations in the lake level can negatively impact the fen community, especially the tamaracks which are sensitive to high water levels caused by beaver activity in the preserve.

The ecological goal for this preserve is to restore or maintain the biodiversity of the tamarack fen and cinquefoil-sedge fens through aggressive invasive species control and management of the lake’s water level.
