“…Forests affect stream function through multiple mechanisms including evapotranspiration (ET) (Link et al, 2005), delivery of instream wood (Benda and Sias, 2003), control of sediment delivery (Piégay et al, 2004), temperature control/shading (Gregory et al, 1991), and allochthonous nutrient delivery (Fisher and Likens, 1973;Naiman et al, 2005). The focus of this study is ET, a fundamental component of water budgets that exerts influence on stream discharge across multiple temporal scales.…”
