Title	Problems in lodgepole pine thinnings basal live limbs and fill-in regeneration
Creator	Cole, Dennis M.
Contributor	Intermountain Research Station (Ogden, Utah)
Description	Leaders that develop from live limbs left on stumps in thinning operations must be removed if thinning goals are to be fully realized. A linear regression model was developed to relate the height of the lowest live limbs of lodgepole pine trees to their age and height, and to the stand density. Three-dimensional graphs show the combinations of age, height, and stand density least likely to have live limbs within 0.5 ft of the ground. Fill-in regeneration was counted at four locations in western Montana and eastern Idaho over a 17-year period following thinnings to five different spacing levels. The amount of lodgepole pine ingress increased with spacing level; however, in the last 6 years of the study, seedling establishment declined at the narrowest (6 by 6 ft) spacing and increased at the widest (18 by 18 ft). Management implications are discussed, and several management guidelines are given.
