Cuyahoga Valley National Park is unusual in that it was created as a National Recreation Area within a ... highly urbanized setting in 1976 before being converted to a National Park in 2000. This setting has provided challenges and opportunities for habitat restoration that are uncommon within the National Park Service.
When established, much of the park’s landscape was disturbed with many areas having been mined, deforested, farmed and/or developed. The park continues to support golf courses and ski resorts.
The park's "Degraded Site Restoration Plan" identifies 40 large, disturbed sites covering more than 700 acres that have contributed huge amounts of sediment to the Cuyahoga River and its tributaries. The project site is one of the 40 sites identified in this plan. CVNP's "Small Disturbed Site Restoration Plan" identifies 230 additional, disturbed sites. All of these sites, plus many more, require reforestation to some degree.
The attached photos indicate the appearance of a mined site at the park prior to soil stabilization and the same site after stabilization and planting with grass. This project would reforest this site to create a contiguous block of large forest in the project area.
As part of this project, we will plant approximately 1,700 trees (3-gallon pots, approximately 6-feet tall) throughout the site. Approximately one-quarter of these trees will be blight-resistant American chestnuts obtained from the American Chestnut Foundation. Park volunteers will remove invasive plants from the site as part of large-group events that park staff will coordinate and supervise. After removing invasives, park staff will work with volunteers to improve soil conditions at this highly disturbed site by trenching furrows and adding composted organic material to planting sites. Trees will be protected from deer browsing after planting by using tree tubes and will be grown by a local nurseryman using seeds collected at the park. Park staff and volunteers will monitor the site in subsequent years and will continue to treat invasive plants until plants trees are established well enough to survive on their own.
