Transpiration of oak trees in the oak savannas of the Southwestern Borderlands region

Abstract

Transpiration of oak trees on the Cascabel watersheds in the savannas on the eastern slope of the Peloncillo Mountains in southwestern New Mexico has been estimated by the sap-flow method. Transpiration represents the largest loss of gross precipitation falling on a watershed in approximations of water budgets for the more densely stocked oak woodlands of the Southwestern Borderlands region (Ffolliott 2000, 2004, Shipek et al. 2004). Knowledge of transpiration is also important, therefore, in developing a general water budget for this more open ecosystem. An initial estimate of the transpiration of oak trees in the oak savannas of the Southwestern Borderlands region is presented in this paper.
