Book excerpt: Excerpt from Periodic Growth of Pole-Sized Ponderosa Pine as Related to Thinning and Selected Environmental FactorsHeight growth of each sample tree was considered to begin on the date immediately preceding the one on which measurable growth was observed. The average beginning of height growth for the sample trees in each crown class-treatment category on each plot was the observation date which immediately preceded a class average height increase of inch or more.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 1979 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1979 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth was analyzed after one thinning in a plantation of pole-size ponderosa and Jeffrey pines on land having a site index of 50 feet at 50 years. Periodic annual increment was determined for each of three 5-year periods. On this basis, increment in diameter and cubic volume were found to he related closely to stand basal area only. Basal area and height increment, however, were also related to time since thinning: basal area growth decreased and height growth increased with each succeeding period. The optimum basal area for volume production (both cubic and board-foot measures) was estimated to be 110 ft2/acre. Optimum stocking levels and resulting stand performance are predicted for a common thinning practice.

Book excerpt: This fascinating study of the role property rights play in preserving natural resources traces the changing uses of the Black Hills National Forest, from its beginnings in 1898 to the present day. Geores argues that, contrary to widely-held notions, local management of property does not lead inevitably to the degradation of resources. Rather, the Black Hills National Forest has flourished as a multiple-use environment when local people have actively helped manage it instead of leaving its care to the Forest Service.
