摘要:This report is the second USDA, Forest Service, Forest Inventory and Analysis (FIA) and State and Private Forestry (S&PF) report of tree planting in the United States based on forest seedling production data gathered directly from forest nurseries. Forest Nursery Seedling Production in the United States replaces the USDA Forest Service, State and Private Forestry (S&PF) annual Tree Planting in the United States report that was discontinued in 2000. The original Tree Planting in the United States report was based on data reported each year by the 50 State forestry agencies and by Federal land management agencies.
