Summary

These data are intended to represent baseline data for wildlife communities and habitat conditions in these parks. They can be used to assess and monitor the park's ecological viability and sustainability.

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.
