Release of sugar pine seedlings and saplings by harvest cutting.

Abstract

Sugar pine, the preferred species to grow on many forest areas in southwestern Oregon, is often seeded or planted on clearcuts there. Advance growth in the form of seedlings, saplings, and poles is common in the mixed- conifer type, and costly planting can be eliminated if this advance growth can be saved during logging and slash disposal. However, if the necessary changes in logging and slash disposal practices are to pay off, long-suppressed understory sugar pine seedlings and saplings must respond satisfactorily to release. A study on the South Umpqua drainage has shown that such sugar pine seedlings will respond with increased height growth after removal of the overstory.
