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.

Growth was strongly related to growing stock level (GSL) for 5 years after thinning 20-year-old poles on Site Index50 115 land at the Elliot Ranch Plantation in northern California. Five GSL's- basal areas anticipated when trees average 10 inches d. b. h. or more - ranging from 40 to 160 square feet per acre were tested. Periodic annual increment (PAI) in diameter decreased curvilinearly from 0.51 to 0.21 inch, with increasing GSL's from 40 to 160. But only trees in plots heavily thinned to GSL 40 (and briefly in GSL 70) grew faster in diameter after thinning than these same trees grew before thinning. PAI in basal area and net volume rose steadily with increasing GSL9s, reaching 9.0 square feet and 255 cubic feet per acre, respectively, at GSL 160. Apparently, even light thinning reduced volume production, but thinning still is recommended to shorten time until first commercial entry and to promote stand health.
