Old growth forests are important to nature’s ecological balance. The trees in these forests provide nesting places for insects, reptiles and amphibians. They improve air quality and water quality while creating a rich topsoil for native plants, flowers and fungi.
Ohio is home to many old growth forests, some with trees dating to 300 years old. Northwest Ohio is home to four old growth forests, each with unique aspects to explore. The Old Growth Forest Network keeps detailed records of forests in Ohio and around the country, with descriptions of flora and fauna as well as directions to find each preserve.
