    Canyon Creek watershed analysis: Ecosystem analysis at the watershed scale
    (2003-06-20) Blue Mountain Ranger District (Or.); David Evans and Associates; Duck Creek Associates
    Characterizes ecological and physical processes at multiple spatial scales by systematically uncovering the interactions of biological, physical, and human processes that have created current conditions. Identifies key questions and conditions, investigates and describes conditions, describes reference conditions, synthesizes and interprets the information, and provides recommendations and management options.

    Galena Watershed analysis--Supplement 2002
    (2003-01-03) Blue Mountain Ranger District (Or.)
    Provides a mid-scale review of 7 subwatersheds in the Middle Fork of the John Day River in supplement to Ecosystem Analysis at the Watershed Scale--Galena Watershed Analysis (1999). Describes the five alternatives of recommended actions for the Southeast Galena Restoration. Early season peak flows have been exacerbated by wildfire adjacent to the area, and has caused elevated stream temperatures during dry months when threatened species of fish depend upon cool water to spawn. Also, the habitat for wildlife has been deteriorating because overstocked, dense stands of trees have inhibited vegetation in the understory that once provided high quality forage for deer and elk. Actions considered include using heavy equipment within stream channels reversing adverse hydraulic and vegetation trends, riparian planting, prescribed harvest and fire, and road decommisioning, closing, and reconstruction.
