Description: These data are the characteristics and acorn counts from 2005 of individual live oak trees found in 0.05-ha circular habitat plots at Spears and Didion Ranches, Placer County, California. Acorns were counted over a 30-second period at each tree using binoculars. Each count involved two 15-second periods, one counting a lower section of a tree and one counting an upper section. Counts were done in mid-September 2005. Trees were tagged with individually numbered 2" diameter aluminum tree tags at 4.5 ft above the ground with the tags facing towards the center of the 0.05-ha sampling plot. There were three 0.05-ha circular habitat sampling plots at each of the 15 sample points, and there were 2-4 oaks per vegetation plot.
