A rare Ohio fen is about to get a lot bigger — and a local family is throwing in their own house to help make it happen.

  • 118 acres proposed for acquisition around Kinnikinnick Fen
  • 450 acres — the preserve's total size if the deal closes
  • 3 acres plus a house the Herron family has offered to donate
  • 1 creek, Kinnikinnick, that depends on the site's water flow

A fen worth protecting

Ross County commissioners voted on Sept. 8 to formally back the Ross County Park District's bid to buy 118 acres surrounding the existing Kinnikinnick Fen and Herron Downs Nature Preserve, near Chillicothe. Fens are rare, spring-fed wetlands that support plants and wildlife found almost nowhere else in the state, and this one has already drawn public tours as a local conservation showcase.

An initial environmental assessment found the property contains a significant water flow path that directly feeds the wetland at Herron Downs. Protecting that upstream land, rather than leaving it open to development, is what would let the preserve grow from its current footprint to an estimated 450 acres.

The family stepping up

The acquisition still depends on funding through Ohio's Clean Ohio program, a voter-approved conservation fund that helps local governments buy and protect natural areas. But the landowners aren't waiting to be asked for more: if the deal is funded, the Herron family has offered to donate the house on the property, along with roughly three acres surrounding it, directly to the park district.

The proposed acquisition would add 118 acres to the conservation landscape surrounding the existing Kinnikinnick Fen and Herron Downs properties — creating one connected habitat instead of another isolated parcel.

That distinction matters for conservation biology. A single large, connected wetland supports more species and recovers better from disturbances like drought or flooding than several small, scattered ones. Buffer land also filters runoff before it reaches the fen, protecting the specialized, often rare plants that only survive in that mineral-rich, spring-fed soil.

The commissioners' letter of support is a required step toward a state funding application, not a guarantee — Ohio's Clean Ohio grants are competitive, and the timeline for a final purchase hasn't been set. Still, the combination of official backing and a willing landowner offering to donate part of the deal puts Kinnikinnick Fen in a strong position.

Herron Downs already offers guided public tours highlighting the site's ecology and history, and the Ross County Park District has managed the existing preserve for years. If the funding comes through, Ross County would end up with one of the larger protected fen complexes in southern Ohio — built not from a single land grab, but from a public agency, a family, and a stretch of critical wetland habitat coming together at the same time.

For a landscape type as globally rare as a calcareous fen, that kind of patient, incremental protection is exactly how lasting conservation usually happens: one funding cycle, one family, one connected acre at a time.
