P. Bettinger et al., FOREST PLANNING IN AN OREGON CASE-STUDY - DEFINING THE PROBLEM AND ATTEMPTING TO MEET GOALS WITH A SPATIAL-ANALYSIS TECHNIQUE, Environmental management, 20(4), 1996, pp. 565-577
Five major management goals were identified for the upper Grande Ronde
River Basin on the Wallowa-Whitman National Forest in northeastern Or
egon: to produce high-quality fish habitat, to maintain elk habitat, t
o restore and maintain forest conditions within the natural range oi v
iability, and to contribute to community economic stability. From the
broad goals, specific goals for stream temperature, habitat effectiven
ess index (HEI), habitat corridors, maintenance of land in late or old
serai stages, and a nondeclining even flow of timber were selected. A
case study was undertaken in a small watershed that is under typical
societal constraints to determine whether one decision support tool, S
NAP II+, could evaluate the selected goals in a single planning exerci
se. Three riparian management strategies and two forest road scenarios
were used. The exclusion of harvest and road-building from riparian z
ones in order to increase habitat protection decreased harvest levels
and net present value but maintained preactivity stream temperatures.
Other resources were generally maintained within prescribed management
levels. Although the technique has limitations (e.g., it does not acc
ount for riparian zones in calculations of forage and cover for HEI, a
nd it can use the maximum but not minimum acreage goal for some resour
ces), it shows promise for evaluating management tradeoffs in watershe
d analysis.
