Summary: Standard field work, 80% trees brown - super early, missed midday water potential due to tank issues

When: Date: 8/26/2020 , Day: 239 , Watch Time: 9:30 am . Where: Tonzi/Vaira Ranch Who: Siyan, Joe Weather: clear, sunny, smoke from wildfire Phenology: 80% of Oak leaves are brown; the earliest date of senescence since site established; almost all leaves of individual trees are torched; may check heat wave last week Summary See Joe’s notes on equipment maintenance and data downloading Read dendrometers Measured soil moisture Measure groundwater well 5. Joe put a new tank (pressed air) at Tonzi for leaf water potential; the connection head size not matched; reported to Joe for a double check Vaira_Grass Site Fence: electronic off. Performances of sensors Closed gate and no electronic fence. Tonzi_Tower Site Fence: electronic off. Performances of sensors 3. closed gate and no electronic fence on. Toniz_Floor Site Fence: electronic off. Performances of sensors: Closed gate and no electronic fence on.
