When: Date: 4/4/2008 , Day: 95 , Watch Time: 11:00 .
Where: Tonzi/Vaira Ranch
Who: Siyan and Jessica
Weather: partially cloudy (4/5)
Phenology: oak leaves out 100%/ green grasses, blooming, blue, purple, and yellow. Talked to Mr. Tonzi. He mentioned that grasses need 3-4 inch. Rainfall during Mar.-Apr. Good to know! The same as we saw from our data!
Summary

1. Three EC systems worked well.
2. The forth depth of soil profile system (may be under trees) was -9999.
3. Collect grass sample and oak leaves and branches for LAI and N, etc.
4. Read dendrometers
5. Took measurement of spectrometer (Youngryle)
