EOS article written by Lily Strelich features research conducted by CZO investigators and their colleagues, which shows that bark beetle epidemics that caused regional-scale tree mortality in many snowmelt-dominated headwater catchments of western North America does not result in annual stream flow increase as previously reported.

Increased evaporation following widespread tree mortality limits streamflow response. Biederman J.A., Harpold A.A., Gochis D.J., Ewers B.E., Reed D.E., Papuga S.A., and Brooks P.D. (2014): Water Resources Research 50(7): 5395–5409
Recent tree die-off has little effect on streamflow in contrast to expected increases from historical studies.
