Where: Tonzi/Vaira Ranch
Who: Siyan, Joe
Weather: clear, sunshine
Phenology: white and yellow flowers at Vaira, yellow and purple flowers at Tonzi, grass stems out, oak leaves still expanding
Summary

1. took Pre-dawn leaf water potential measurements
2. measured A-Ci and A-PAR curves for oak and gray pine
3. checked and download data at Tower, Floor, and Vaira. Three systems are working fine.
4. Calibrated Li-800 in the field (bring the copy of Ted’s instruction).
5. Collected grass sample for LAI and phenology in Tower and Vaira, oak branches
6. read dendrometers
7. measured soil moisture probes
8. took spectrometer measurement at Vaira and Tonzi
9. camera: field pictures
