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.
The Oregon Coast Range contains large acreages of nonstocked
high site land. With the increasing demand for wood products, more
attention is being given to the problems of reforesting these lands.
This study develops financial guidelines to the reforestation
of nonstocked high site lands. A number of possible owner constraints...
Reforestation of certain areas of southwestern Oregon has become a serious problem. Reforestation failures are evident in numerous clear-cut stands, but failures are also noted in various partially-cut stands. The Dead Indian Plateau, approximately twenty miles east of Ashland, Oregon, has many areas where this is evident. This study investigated...
The purpose of this thesis is to determine if the Oregon State
Forestry Department's stocking survey system can be applied to planted
acres as well as to seeded acres. Two computer programs were developed
into a primary program. One produced a new stocking curve adapted to
hand planting patterns, and...
The purpose of this study was to investigate the use of a multistage with probability proportional to size (FPS) sampling design using
aerial photography to sample coniferous regeneration on clearcuts.
To date, aerial photography has not proven to be as economical
(because of the high cost of specialized photography required)...
Clearcut and shelterwood reproduction methods are both important, silviculturally viable reforestation tools for southwest Oregon. The ecology of local forests lends itself to the successful application of either method, in most cases; thus, choice of method is typically based on land management objectives, which integrate social and resource values, economics,...
