Foresters believe that millions of acres in the United States should be planted to 

 trees. Nurseries throughout the country produce seedlings for public and private 

 forests. In a Georgia nursery, above, longleaf pine seedbeds are being sprayed with 

 bordeaux mixture to control brown spot disease. Below: Tree-planting machine 

 in Bienville Parish, Louisiana, can plant up to 10,000 seedlings a day. A colter 

 wheel slices the sod; a trencher opens the cut; the operator spots seedlings at the 

 right depth and spacing; finally, wheels behind pack the seedlings. Hand plant- 

 ing, though much slower, still must be used on areas of rough and rocky terrain.
