Title: Sapflow and xylem water isotopes from Snodgrass Mountain, East River Watershed, Colorado USA

Abstract

This dataset includes sapflux and stable water isotopes of soil water and xylem water for aspen, fir and spruce trees along the Snodgrass Mountain transect in the East River Watershed, Colorado USA. The purpose of generating this dataset was to understand: (1) the total flux of water being used by trees in the watershed, (2) separate the component of transpiration that was derived from recent precipitation vs. older water such as winter precipitation of groundwater and (3) understand how total water use and water sources for the trees varies between species and position on a hillslope. This work will be combined with hydrological simulations to place better constraints on the flow paths of water through the East River Watershed. The data were collected from May to September of 2019 though collections are ongoing through 2021. The sap flux data were collected using ICT SFM1 sensors and are presented in units of cm/hour after having been corrected using estimates of wounding diameter, water content of wood and sap wood depth. The xylem water isotope data were collected approximately weekly from each of the trees instrumented with sap flux. The stems were collected and the water extracted using classic cryogenic methods.
