In recent years we have seen increasing debate over
the allocation of PNW water resources. In particular there
are conflicts over using the river system for irrigation
vs. electricity production. Denying the hydroelectric
system water implies higher costs to electricity consumers
as producers substitute more expensive nonhydro resources.

The PATH algorithm, which is the efficient dynamic
programming algorithm developed by Paredes and Brodie
(1987) was interpreted from a different point of view.
This modification of the PATH algorithm by the calculus of
variations vastly diminished the calculation task and
memory required to store optimal stands at each stage....
A 20-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stand in the Oregon Coast Range was thinned from about 1,700 to about 350 trees/ac. Subsequent thinnings, under eight different regimes, occurred at ages 23, 27, 30, and 32. Average net periodic cubic-volume growth was strongly influenced by thinning regime, varying from about...
Shallow, rapid soil mass movements are common events and primary sources
of sediment in steep terrain of the Pacific Northwest.
Poorly vegetated debris deposits and scars resulting from landslides
remove land from the productive timber base, and are subject to
continuing erosion. To examine the impact of these events on...
The ski areas of Oregon and Washington are similar in
many [respects], especially in that they are predominately local day
areas and are located on United States Forest Service lands. The
demand for more ski facilities is apparent yet the number of new
areas opening has decreased over the years....
During summer and fall of 1981 to 1983, mark-recapture was
conducted in riparian and upland habitats within old-growth and
mature forests in the Cascade Range of Oregon. Number of
individuals and species richness were greater in riparian than
upland habitat. For most species, the mean adult weights and
the percentages...
