... to produce a thousand board feet 
sawtimber by the year 2000. 
Annual crop 
of pine seedlings... 
Growing sawtimber is a long-time under- 
taking. On the average it takes from 45 
to 50 years to grow a 12-inch yellow-pine 
tree in North Carolina. The pine seedlings 
that will provide the pine sawtimber 
needed in the year 2000 must be estab- 
lished now. 
It takes about eleven 12-inch pine trees 
to produce 1,000 board-feet of lumber. 
For every 12-inch pine needed in the year 
2000, at least 9 pine seedlings must be 
established now. By that time, 8 of the 9 
will have been taken out by natural mor- 
tality or removed in cutting operations for 
small products.
