“…Don. ), radiata pine (Pinus radiata D. Don), Norway spruce, ponderosa pine, and coast Douglas-fir have found stub length was far more important in delaying occlusion than stub width (Hogan 1957, Lohrey 1963, Takeuchi 1981, Gosnell 1987, Vadla 1989, O'Hara and Buckland 1996, Petruncio et al 1997.

“…Another common finding in pruning studies with both conifers and broad leaves is more rapid occlusion in trees with faster radial growth rates (Mayer-Wegelin 1936, Roth 1948, Lohrey 1963, O'Hara and Buckland 1996, Petruncio et al 1997). More rapid radial growth rates indicate greater xylem production and result in more rapid occlusion.…”

The proper method for branch removal is a long-standing question in forestry. If the branch is cut flush with the stem, a larger wound results, but if the branch is cut further from the stem, the resultant clearwood production will be less. Both alternatives have implications for tree health and wood quality. A long, international history of forest pruning research generally indicates that a cut parallel and close to the stem will maximize clearwood production without excessive stem decay. Some exceptions exist for species where potential for stem decay is high. The method recommended in most guidelines for all types of pruning is an outside branch collar approach based primarily on a small number of observational studies. However, maintaining tree health and maximizing clearwood production are not mutually exclusive and a cut close to the stem can meet both objectives. Alternative approaches to branch removal may be useful for other objectives.
