Abstract
Ecosystem analysis finds the watersheds are a critical source of relatively cool water for the entire Umatilla Subbasin, the Umatilla River and Meacham Creek provide some areas of relatively high quality conditions for remnant and recovering fish populations, bull trout populations are at risk because of their small population and limited satisfactory habitat with less than ideal water temperature conditions, coldwater source protection may conflict with high priority vegetation management activities, overstocked stands with dense understories invite wildfires, a high risk of infestation exists from western spruce budworm and Douglas-fir tussock moth, and ten native plant species are at risk. Vegetation analysis describes the potential vegetation, cover types, size classes, structural stages, density (canopy cover), and disturbance processes. Also includes the historical range of variability for forest structural stages, consideration of limited vegetation components, and an assessment of and suggestions for stocking levels for various tree species.

"The Umatilla-Meacham ecosystem analysis area is located on the Walla Walla Ranger District of
the Umatilla National Forest. The analysis area lies on the west flank of the Blue Mountains in
the headwaters of the Umatilla River subbasin (HUC #17070103), about 25 miles east of
Pendleton, Oregon (Figure 1-1). Together, the two watersheds (Umatilla and Meacham) amount
to about 200,700 acres, or about 313.5 square miles in area. About 70 percent of the analysis
area is National Forest land (Figure 1-2)."
Date of Upland forest vegetation analysis is October 1994.
