Knoxville's urban wilderness: Moving toward sustainable multifunctional management

The Knoxville Urban Wilderness (KUW) in Eastern Tennessee is part of a larger global trend of acquiring vacant lands within urban landscapes for their natural habitat and recreation value. At 688 ha, the KUW is one of the largest urban wilderness areas in the United States, consisting of loosely-connected land parcels with multiple stakeholders including state, county, and city governments and private foundations. Here we use the KUW as a case study to address critical questions of management that arise for most urban wilderness projects globally: What should these areas be managed for, and how should they be managed? How can multiple stakeholders be efficiently organized to pool their resources most effectively. The KUW is currently used mainly for recreation and its potential for biodiversity conservation and education and ecosystem services is largely unutilized. As a way to promote and manage this unused potential, we began the first ecological inventory, compiling existing data and conducting biodiversity and invasive plant surveys with citizen scientists. We found that the KUW harbors a significant number of plant (250) and bird (193) species, with many other taxa also identified. We also found widespread infestation of invasive plants for which we provide management suggestions. A preliminary visitor survey shows that most visitors (about two-thirds) are from the immediate vicinity, mainly for walking (74.4%) or biking (19.9%). The vast majority (93.7%) of visitors do not want more vegetation management or removal and 98.3% of visitors would like to see the KUW expanded in area.
