Effects of mountain beaver management and thinning on 15-year-old Douglas fir growth and survival.
We examined 4-year growth of 15-year-old damaged and undamaged Douglas fir (Pseudotsuga menzesii) after integrating temporary population reductions of mountain beaver (Aplodontia rufa) with thinning in a pre-commercial hand-planted plantation in western Washington. Five treatment combinations were considered: (1) trapping mountain beavers in an unthinned area, (2) trapping before thinning to 65...

متن کاملFour Years of Epiphyte Colonization in Douglas-fir Forest Canopies
In 1995, we installed surface-sterilized, rough-barked and smooth-barked tree branches in clearcuts, young forests, and old growth. Half of the experimental branches were inoculated with propagules of the epiphytic cyanolichen, Lobaria oregana. In 1997, we concluded that L. oregana was associated with old-growth Douglas-fir forests because of dispersal limitation; addition of L. oregana propagu...
متن کاملActivity Patterns of Marbled Murrelets in Douglas-fir Old-growth Forests of the Oregon Coast Range
Activity patterns of Marbled Murrelets (Brachyramphus marmoratus) were monitored on a near-daily basis during three breeding seasons at five inland forest sites in the Oregon Coast Range. Four daily activity metrics (numbers of daily detections, vocalizations, occupied detections, and duration of daily activity) were monitored and each was highly variable within and among sites and years. We ob...
متن کاملNative forest pathogens facilitate persistence of Douglas-fir in old-growth forests of northwestern California
Forest pathogens and insects can accelerate tree mortality, increase stand structural heterogeneity, and alter tree community composition. In northern California, the canopy trees Abies concolor var. lowiana (Gord. & Glend.) Lemmon (white fir) and Pseudotsuga menziesii var. menziesii (Mirbel) Franco (Douglas-fir) co-occur but vary in shade tolerance and regenerative abilities following disturba...
