Abstract

Oaks are a keystone species in California ecosystems that aid in regulating ecological processes and support a variety of wildlife species. There is mounting documentation that California oak species are experiencing a lack of recruitment and declines in populations. Agencies have responded with restoration projects for oaks; some projects, such as those implemented by the U.S. Forest Service, have multiple use management goals, such as timber harvesting, fire fuel reduction, and oak restoration. However, the effectiveness of such multiple use projects, in which restoration is one of the goals, has not been well studied. I evaluated the response of black oaks at two US Forest Service multiple use projects in the Shasta-Trinity National Forest in Northern California. I found that black oak tree and sapling recruitment did not show increases in conifer removal sites over non-conifer removal sites, suggesting that black oaks derived little benefit from multiple use management.
