California and in Texas. In four regions, more 

 than 50 percent of aU the forest land is noncom- 

 mercial: 84 percent in the Plains, 77 percent in the 

 Southern Rocky Mountain Region, 74 percent in 

 Coastal Alaska, and 59 percent in California. East 

 of the Plains, only New York, Florida, and Min- 

 nesota have more than one million acres of non- 

 commercial forest land (fig. 53) . 



Noncommercial forests are made up of various 

 forest types. Productive but reserved lands, widely 

 scattered through forest areas, carry the same 

 types that appear on commercial forest land. 

 This is also true — though to a lesser extent — of 

 some of the unproductive forest areas such as the 

 forested swamps in the Lake States; the precipi- 

 tous coastal slopes in Coastal Alaska, with their 

 sparse tree cover; and the extremely poor sites 

 occurring mainly at the higher elevations in the 

 West, and characterized generally by rocky, shal- 

 low soils. However, much of the unproductive 

 acreage in the West occurs along the dry lower 

 margins of commercial forests. Here the greatest
