Sapflow and stomatal conductance data in 3 savanna tree species

This dataset includes both sap flow and stomatal conductance data for 3 woody savanna species (11 individuals of Colophospermum mopane, and each 9 of both Senegalia mellifera and Catophractes alexandri). Each data point contains information on a browsing level that has been manually applied to an individual plant plus information on environmental conditions.

Methods
Data were collected in a nature reserve in the Kunene region, Namibia. Sap flow measurements followed the thermal heat dissipation method established by Granier (1985, 1987). To prevent any NTG-related bias in sap flow estimates, we applied the cyclic heat dissipation method after Lubczynski et al. (2012). Raw data was logged every 30 seconds and processed data provided sap flow densities with a 30-minute resolution. Stomatal Conductance was measured with a Decagon Devices Leaf Porometer on the bottom side of the leaves (abaxial). Climatic and soil moisture data were obtained from a local weather station.
