Table 4.5—Simulated effects of selected futures on projected employment and wages and salaries in forest industries, investments in 
plants and equipment, State and local government revenues, in the South, selected years 1984—2030—Continued 
' The future as described by the basic assumptions and other specified and implied assumptions underlying the projections in chapter 3. 
The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by increasing softwood lumber and plywood 
yields by 25 percent instead of the 10-percent increase assumed in the 1979 Assessment and the Supplement. The increase in yields will be staged in the progres- 
sion 9, 7, 5, 3, and 1 percent per decade. 
3 The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by increasing the projected exports of lumber, 
plywood, and pulpwood (includes pulpwood and the pulpwood equivalent of pulp, paper, and board) by 20 percent in 1990, 40 percent in 2000, 60 percent in 
2010, 80 percent in 2020, and 100 percent in 2030. 
+ The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by increasing the projected imports of plywood, 
pulpwood (includes pulpwood and the pulpwood equivalent of pulp, paper, and board), and hardwood lumber and logs by 20 percent in 1990, 40 percent in 2000. 60 
percent in 2010, 80 percent in 2020, and 100 percent in 2030. 
> The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by reducing the projected area in timberland 
in the South by 2 million acres in 1990, 5 million acres in 2000, and 11 million acres in 2030. 
© The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by reducing the net annual growth on pine 
plantations, natural pine, and mixed pine—hardwood stands shown in the empirical yield tables used in developing the base level projections by 25 percent. 
’ The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by reducing timber harvests on the national 
forests to 8.1 billion board feet in 1990 and maintaining this level through 2030. 
* The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by assuming that all the marginal cropland 
and pasture in the South that would yield higher rates of return in pine plantations would naturally revert to timberland by 2000 (70 percent natural pine, 30 per- 
cent hardwoods in the Southeast; 40 percent natural pine, 60 percent hardwoods in the South Central). 
° The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by assuming that all the marginal cropland 
and pasture in the South would be planted in pine. 
'0 The future as described by the basic assumptions and other specified and implied assumptions in chapter 3 modified by assuming that all the economic opportunities, 
except those involving intermediate stand treatment and those not involving area change and management types, for increasing timber supplies on timberland in 
private ownerships that yield 4 percent or more net of inflation or deflation would be utilized.

nities to increase timber supplies on forest industry timberlands in the Douglas-fir region would be utilized.
