Abstract

Well-stocked patches of vigorous advance reproduction are found in many deteriorating old-growth stands in southwestern Oregon. If carefully released from the over story, this reproduction can shorten the rotation length of the next crop by many years. Often sugar pine is the fastest-growing component of the reproduction, but it is frequently infected with blister rust. Should a sanitation pruning be made to save these trees within areas being managed for sugar pine? A 1952 survey on the South Umpqua Experimental Forest in 1952 indicated that the number of sugar pine crop trees could probably be increased by removing cankered branches. Two subsequent projects demonstrated that such pruning was feasible.
