Excerpt from Growth of Ponderosa Pine Thinned to Different Stocking Levels in Northern Arizona This study demonstrates that the ability of Rocky Mountain ponderosa pine (pinus ponderosa var. Scopulorum Engelm.) to respond to stand treatment pro vides considerable flexibility for the manager to choose initial stand management strategies. Furthermore, it still permits future changes as management objectives or market conditions change. Early predictions (schubert 1971) and the 20-year results presented here differ considerably, indicating that volume production estimates covering long periods of time should be interpreted with care. Management guidelines involving intermediate entries, however, can be formulated with a greater degree of certainty. For example, the study results suggest that a reasonable cutting cycle would be about 20 years, provided that there is a roundwood market when the second thinning is made. For sawtimber yields, in contrast, the minimum elapsed time between the first and second thinning appears to be about 30 years, with longer cut ting cycles necessary if a minimum diameter limit of greater than 7 inches cm) is desired.

Excerpt from Twenty-Year Growth of Ponderosa Pine Saplings Thinned to Five Spacings in Central Oregon Stand density and understory vegeta tion have had significant effects on height growth throughout 20 years of observation following thinning. Under story vegetation has had the greatest effect on height growth at the wider spacings, reducing growth from 15 to 50 percent during some periods. Twenty years after thinning, low density plots contain less woo'd fiber than high density plots. On the other hand, widely spaced trees are much larger than narrowly spaced trees and collectively are now producing almost as much wood volume annually as high density plots. Even though most of the trees left after thinning were 70 years old, stagnated, and suppressed by overstory, they have responded well to overstory removal and release, and trees at the three widest spacings appear capable of producing a usable crop of timber despite their advanced age.
