Prospective Stocking 



Loblolly- Shortleaf Pine and Longleaf - 

 Slash Pine Type Groups 



Standards for prospective stocking based on 

 seed trees and pro.ximity to a seed source con- 

 sisting of a group, strip, or stand of seed-bearing 

 trees were as follows: 





Average number of pines re- 





quired per acre to rate 100
