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.
