Complete removal of residues, as done in this study, definitely retards es tabl ishment and early development of tree seed1 i ngs . However, reasons for this detrimental effect are not totally clear at this point, and it is doubtful that this particular study can shed much more light on the reasons. Five years is a small segment of a tree's life on these cold subalpine si tes , but lodqepol e pine es tabl i shment and growth trends apparent 5 years after treatment discourage use of the chips-spread and complete residues-removal treatments. Lodgepole pine is a true pioneer species, capable of capitalizing on highly disturbed conditions such as those following scarification or burning. These "raw" condi tions may be the very thing that helps lodgepole pine maintain its competitive advantage over many of its associates . A1 1 of the natural and artificial regeneration treatments that were tested here are acceptabl e and productive methods of regenerati ng lodgepol e pine forests. With natural regeneration, the key lies in timing site preparation wi th anticipated seed crops. \Ji th artificial regeneration, the key lies in proper site preparation for both seeding and planting and proper handling of stock from the nursery through the planting process. Even if residue treatment effects on lodgepole pine tree and stand development do not persist beyond the juveni 1 e stage, a number of important management objectives are affected. Included are: getting trees large enough to resist rodent and livestock damage, providing a stand tall enough to provide hiding cover for game, restoring a forested appearance, and the obvious goals of increasing wood production and shor teni ng rota ti ons .
