Gross Woods State Nature Preserve was made possible by a gift of the heirs of Samuel Gross to the Division of Natural Areas and Preserves via the Ohio Chapter of The Nature Conservancy in 1980. Although small in size, Gross Woods is one of the least disturbed old-growth woods in west-central Ohio and one of the few mixed-species swamp forests remaining in this part of the state.

• Numerous large trees
• Excellent spring wildflowers
• Good bird habitat

The woods are characterized by a diversity of tree species, with no one type being dominant. Large bur oaks and basswood occur in the wettest areas, with shagbark hickory, white and red oaks, black walnut, beech, and sugar maple on the slightly drier ground. Rare pumpkin ash is also present here.

The display of spring wildflowers and the brilliance of autumn colors makes visiting Gross Memorial Woods rewarding at any season.

Located in Shelby County, 6 miles east of I-75 (Botkins exit) and approximately 3.5 miles north of Jackson Center on Botkins Road. Boardwalk and trail system are present.
