Successful regeneration of forest stands often requires that crop trees be released from competing vegetation. This publication provides basic information on how to determine if release is necessary and methods for release.
This publication focuses on even aged, fully stocked, Douglas-fir
stands. Because of fire history and past harvesting patterns, such stands
dominate west of the Cascades throughout much of Oregon, Washington,
and northern California. Stand volumes and dollar values will be
different for other species.
Recently reforested sites revegetate quickly after timber harvesting.
Competition for essential growth elements—sunlight, moisture, and
nutrients—often depresses the vigor and survival of the desired
crop trees. Competition comes from grasses, broadleaf weeds called forbs,
shrubs, or less valuable tree species.
Successful reforestation of your harvested timberland is more than just
planting a few trees and hoping they will grow. To ensure success,
you first must answer several key questions:
• What species should I plant?
• What kind of seedlings should I select?
• How can I tell whether their...
Western hemlock forests in the coastal areas of Oregon are some of
the most productive and diverse forests in the world. This rich
diversity represents both a challenge and an opportunity for woodland owners interested in managing western hemlock on their property.
