Sherman Island: 2010-08-11 09:15:00 (DOY 223)
Author: Jaclyn Hatala

Sherman: Arrived around 9:15am, cool temperatures with a strong breeze from the W/SW. Cows were in the far northwest corner of the field, but there was plenty of "fresh evidence" that they had recently been closer to the tower. It seems like a lot of the plants are doing quite well. The field is more a patchwork of different types of plants at this point, with pepperweed, grasses, a bunch of unidentified herbaceous species, and even some patches of clover. Mean LAI was 4.5. I took spectral reflectance measurements, 5 biomass clip plots, and measured LAI along the 200m transect with the LAI-2200. Water table was 57cm in the enclosure, 52cm in the south well, and the north well is still dry.
