Johnson Woods is one of Ohio's largest and best remaining old-growth forests.
Many trees rise 40-50 feet before the first limbs occur and several are more than 400 years old. Some are 120 feet tall with a diameter of 4 to 5 feet.
The 155-acre tract on the south side of Fox Lake Road was a gift to the Ohio Division of Natural Areas and Preserves from Mrs. Clela Johnson and her family in memory of her late husband, Andrew C. Johnson. In addition to the gift, Mrs. Johnson sold 51 acres of adjacent old-growth woods on the north side of the road to the division. This tract was purchased with Ohio Income Tax Checkoff donations.
