Named in honor of Chief Cornplanter,the famous Native American leader of the Seneca tribe, who maintained peace between the fledgling United States government and the Iroquois from 1784 to 1812. Today, Cornplanter State Forest covers 1,585 acres in Forest, Crawford and Warren counties. It is one of eight state forests located in the PA Wilds region.

Invasive Plants Targeted with Herbicide Applications
The Anders Run Natural Area in Warren County will be treated with herbicides during ideal conditions in the months of July and August. Herbicide operations will target only invasive plant species that are found throughout this old growth forest. Controlling invasive species allows native plants to thrive and natural processes to occur. For more information please contact the Cornplanter State Forest district office at 814-723-0262 or email:
Road and Trail Advisories
Due to oil development, trails in the eastern portion of the Hunter Run Division are being affected by road construction as well as increased traffic. Visitors should proceed with caution in areas of drilling activity.
Don't Move Firewood
To help protect the forest from invasive insects that can kill trees and devastate the ecosystem, please do not transport firewood over long distances. Firewood can harbor insects such as emerald ash borer. Cut or purchase your firewood where you intend to burn it.
