Occurrence of shrubs and herbaceous vegetation after clear cutting old-growth Douglas-fir in the Oregon Cascades.

Abstract

Land managers often express a need for more complete information about the vegetative cover that develops on cutover areas between harvest of old-growth Douglas-fir (Pseudotsuga menziesii) and establishment of a young-growth forest. The composition and density of this cover frequently determines the management techniques that must be used to establish the new stand and provide for watershed and wildlife resources. This paper presents data on the frequency of occurrence of shrub and herbaceous species during the first 6 years after logging and slash burning. The study was made on 14 clearcut units in the H. J. Andrews Experimental Forest, located on the west slope of the Cascade Range, near Blue River, Oreg. The units were in the Lookout Creek drainage, 1,850 to 3, 800 feet above sea level, with slopes ranging from almost flat to nearly 100 percent. Nine units had northerly aspects; five, southerly.
