Abstract

Measurement of sap flux in mature oak trees at the CZO Garner Run catchment in Rothrock State Forest during the entire year. Motivation for study is to monitor actual water usage of trees in order to understand water flux rates throughout the water catchment. The tree ID numbers are 3158, 144, 3164, and 180. Additionally, the data helps to understand the soil, plant, atmosphere continuum (SPAC) at the CZO. Measurements are made using four Dynamax Thermal Dissipation sensor (TDP) with 30 millimeter probes. These are connected to a Campbell Scientific CR1000 data logger that are manually downloaded monthly.

Data collected using paired temperature probes installed in trees and insulated. In each tree one probe produces a small amount of heat, the other probe measures the ambient temperature of the sap. The greater the sap flux in a tree the greater the voltage difference in the probes.
