    Four studies (two with loblolly and two with slash pine) show an effect of number of stems per acre on mean dominant and codominant height. One slash pine study averaeed a 1-foot decrease in mean height at age 30 for each 100-tree increase in planting density over the range of 200 to 1200 seedlings per acre. Ignoring this density-height effect in a growth projection model developed from the same slash pine data resulted in over-estimating growth by as much as 46 percent.
