History
Forest, Ohio was established in the nineteenth century as settlers moved into the fertile lands of Hardin County following the drainage of the Great Black Swamp, which opened much of northwestern Ohio to agriculture and development. The arrival of the railroad in the region during the latter half of the 1800s helped small communities like Forest grow by enabling the transport of agricultural goods to larger markets. Over the decades, Forest has maintained its identity as a rural agricultural community, preserving its small-town heritage while adapting to the changes of modern rural life.
