摘要

We appreciate the comments by Graham and Hubbert (2012) regarding our finding (Bales et al., 2011) that water stored in deeper soils and weathered granitic rock (regolith) provides a significant fraction of water for forest evapotranspiration. Our multi-year hydro-logic measurements confirm and complement their earlier finding that moisture supplies deeper in the critical zone maintain healthy forested ecosystems in the southern Sierra Nevada despite shallow soils and a typical long dry season duringthe summer and fall. Indeed, we were unaware of some of the references presented in their comment, specifically the early reference by Arkley (1981), who suggested for the first time that the decomposed granitic rock and associated deep moisture may provide for tree water use during periods of no rain and account for tree survival. While we did reference one study by Rossi and Graham (2010) that directly related to specifics of our monitoring network, we regret that we overlooked the opportunity to expand on this existing body of research in the context of our discussion of the water balance. Although we did not cite Wahrhaftig (1965) in the current paper, it was his seminal work that in part motivated the multi-disciplinary, integrated study of the critical zone now being performed at the Southern Sierra Critical Zone Observatory (SSCZO), the location of our research.
