These data are the total number and average number of saplings and seedlings of trees detected from 0.05-ha circular plot habitat samples taken in 2005 at sample points at Spears and Didion Ranches, Placer County, California. Seedlings and saplings were counted from nine 1-square meter (0.56-m radius) circular plots located within each 0.05-ha circular habitat sampling plot. There were three 0.05-ha circular habitat sampling plots at each of the 15 sample points. One 1-square meter plot was located at the center of 0.05-ha plot, and the eight remaining plots were located 8 m away from the center point at 45 degree intervals in the circular.
