Project Name: Moss Rock Oak Release |
|
Background Information: The project is being conducted on a 5-ac private parcel in a
rural residential neighborhood north of Corvallis, OR. Landowner’s Joan Hagar
and Dave Vesely were motivated to undertake the project in an attempt to save a
number of Oregon white oaks that were over-topped by conifers and bigleaf
maple. The release thinning started in October 2004 and is expected to be
completed in summer 2005. To date, project costs have been paid by the landowners
through the sale of Douglas-firs harvested during the thinning.
Goals and Objectives: The principle goal of the project is to sustain a patch of Oregon white oak woodland on a landscape that is otherwise dominated by conifers and bigleaf maple. A secondary goal is to reduce wildfire hazard around the home on the property. Activities also will be directed toward increasing the availability of acorns for wildlife and protecting uncommon native plants from invasive weeds. Restoration Methods and Activities: Tree removal is being concentrated on the 4-16 inch dbh grand fir, Douglas-fir, and bigleaf maple. Trees in this size class seem to be having the most impact on the development of oak crowns. Approximately 10 very large conifers (diameter >20-in dbh) are being retained on the site for red-tailed hawks and owls that nest on the property. All snags >6-in dbh are being retained for wildlife. Oaks that have lost too much crown to respond to the thinning will be cut to encourage stump sprouting. Oak seedlings will be planted between 2006-2008. False-brome is a significant threat to native understory plants on the property. Control of this weed will be accomplished by spot spraying with Fusiladetm and possibly grazing by sheep. Lessons Learned: Logging in a densely-populated rural residential area demanded close attention to the impacts of the project on neighbors. Some people worried about the safety of children and pedestrians while trees were being felled. Others wanted to know how we were going to keep logging slash from being a fire hazard. Everybody wanted assurance that logs or machines wouldn’t damage the roads. Hiring a logger that is familiar with these issues and can be diplomatic is extremely important if you want to maintain harmony in your neighborhood.
