Crall Woods is known regionally through an extensive study performed by the Ohio Biological Survey (1964) that resulted in the publication of the Ohio Biological Survey book entitled An Ecological Study of Crall Woods: A Remnant of Forest Primeval in Ashland County, Ohio. It is also known nationally through the designation of the area as a National Natural Landmark by the National Park Service (1974).

Given the unique characteristics of this park, Crall Woods is maintained as a natural area.

Crall Woods is on the south side of US-224, and Sauers Farm is on the north side of the highway.

The Sauers Family originally acquired this farm in the 1930s and it was known throughout the area as Pine Hill because of the pine trees that lined the adjacent roads. Many of these pine trees still exist. While a substantial portion of the old farmstead is currently being naturalized, a portion will also be managed as a farm to showcase our agricultural heritage.
