Correction

Our recent article “AGU meeting covers key environmental issues” (Vol. 22, No. 1) included an incorrect citation for a paper about “Zhang Curves” that describe changes in water yield that may occur with land use conversion from forest to grasslands. The correct citation is: Zhang, L., W.R. Dawes, and G.R. Walker. 2001. Response of mean annual evapotranspiration to vegetation changes at catchment scale. Water Resources Research 37:701-708.

Thanks to Dr. Ge Sun, forest hydrologist with the USDA Forest Service, for bringing this error to our attention.
