Cross-site comparisons reveal varying long term trends in nitrogen exports, and varying responses to warming trends. Although theory predicts that streamflow should recover quickly after disturbance, paired watershed comparisons found decreases in summer flow (relative to undisturbed watersheds) in regenerating post-harvest forests 25 to 45 years old.
