2007 Northwest science  
An increase in land dominated by young second-growth Douglas-fir forests in the Pacific Northwest has coincided with heightened concerns over loss of old-growth habitat.  ...  Average growth of Douglas-fir increased in all thinned stands, but growth of the largest Douglas-fir trees was only accelerated in the heavy thin.  ...  To address these questions, the overall objective of this study was to characterize early overstory response following alternative thinning treatments in young Douglas-fir stands.  ...
