Sugar Pine Seedling Size--A Reflection of Seed Handling?
Until a few years ago seed procurement for tree nurseries was a relatively minor activity in California. But in 1960, a good seed year, the California Division of Forestry collected nearly 4 tons of tree seed valued at about $35,000 (4). The same year, the California Region of the U.S. Forest Service collected and purchased nearly 6 tons of seeds. This amount plus the inventory in storage was valued at $88,000 (2). Such expenditures probably will increase; therefore, steps to insure quality control are certainly justified.
