Seeing the climate through the trees: observing climate and forestry impacts on streamflow using a 60-year record

摘要: Paired watershed experiments involving the removal or manipulation of forest cover in one watersheds have been conducted for more than a century to quantify impact forestry operations on streamflow. Because climate variability is expected be large, treatment effects would undetectable without treatment–control comparison. New understanding provides an opportunity examine whether interacts with treatments, predictable manner. Here, we use data from H. J. Andrews Experimental Forest, Oregon, USA, El Nino-Southern Oscillation streamflow linked harvesting. Our results show that contrast between Nino and La Nina events so large that, whatever state treated terms regrowth canopy, extreme climatic related remains dominant driver response at this location. Improvements forecasting interannual variation might used minimize treatments by avoiding initial years. Copyright © 2014 John Wiley & Sons, Ltd.
