Abstract
The extent of Oregon white oak woodland and savanna ecosystems in the Pacific Northwest has diminished significantly during the past century, and planting of Oregon white oak seedlings is often necessary for restoring these plant communities. Our objective was to evaluate the effects of tree shelters, control of competing vegetation, fertilization, irrigation, and planting date on seedling growth and survival. Although survival rates were generally high, solid-walled tree shelters increased mean annual height growth. Plastic mulch increased soil water content and height growth. Controlled-release fertilizer did not increase seedling growth but weekly irrigation, when accompanied by mulch, increased first-year growth.
