Redwood, R. 1975 Journal White Cloud campground, 4300 ft., 1 1/2 mi. E Nevada City (by rd.), Nevada Co., Calif. 24 August There was a small (~5 ha) triangular flat area W of the campground there, which seemed like a possible area for study. I also looked around the area of the Sunflowe development and saw 1 squirrel there. I then went back to buy 20 and took the Gold Bug Min. road W for mins. That put me on a relatively flat hilltop, ~5500 ft. The vegetation was mixed - mostly Douglas Fir and White Fir. In 30 min. of walking, I found 31 holes that looked like they'd been dug by chickarees, remains of 7 White Fir cones, 4 whole White Fir cones, and 1 tree with ~25 Ponderosa Pine cones under it, two others with 65 under them. I heard 1 alarm call after the walk. Many of the White Firs had 20-50 cones on them. I then returned to the campground. 25 August I got dry ice in Nevada City in the early morning, then spent 0710-0900, 1025-1240, 1500-2000 in the study area hearing 18 churring calls and catching 3 squirrels. Wind 0-15 yz., sky clear. Temp. 60°F at 0800, 78°F 1500, 68°F at 2000. I also caught a chipmunk, E. quadrimaculatus, 1 think, ~30 in. S FS, near a large Incense Cedar log. 26 August I spent 0630-0915, 1000-1230, 1400 just to check traps, and 1215-1950 in the study area hearing 22 churring calls. I spent 1430-1615 on a broad flat hilltop N. of the 30.00 mile marker, a half mile NE of the campground. The vegetation is about the same as it is in the campground, but with fewer Ponderosa pines and oaks. In a 30 min. walk, I found 20 holes, about half a dozen of which were large and may have been made by Gray squirrels. I also found 2 remains of White Fir cones.
