ford, Rolf R. 1974 Journal 5 Sept. White Cloud campground, 11 miles east of Nevada City, Nevada Co., Calif. ~4300 ft. Table of location and approximate seed production of seed producing conifers near White Cloud campground. Most if not all cones cut this year were collected and put in a pile near the tree. In some cases the trees were too close to each other for there cones to be assigned to a particular tree. These are grouped together. Estimation of cones still on the tree was done by counting from a good vantage point, then multiplying by 1.5.
