Book excerpt: Excerpt from Ten-Year Performance of Ponderosa Pine Provenances in the Great Plains of North America The variety arizonica [engelm.) Shaw - Pinus orizon ica according to some authorities - extends from south west New Mexico and southeastern Arizona southward along the Sierra Madre Occidental to near Durango, and along the Sierra Madre Oriental to near San Luis Potosi, Mexico. Although older studies of ponderosa pine - near Pikes Peak in Colorado and Priest River, Idaho (1911) - are considered to be the earliest examples of provenance tests of forest trees in North America (wang subsequent genetic research in ponderosa pine has concentrated mainly on the West Coast variety ponderosa.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Ponderosa pine trees representing 79 provenances were tested near Towner, N. Dak. Eight provenances can be recommended for planting in the northern Great Plains, based on 10 years in the plantation: 721 (Valentine, Nebr.); 720 (Ainsworth, Nebr.); 811 (Jordan, Mont.); (722 Chadron, Nebr.); 703 (Cave Hills, S. Dak.); 816 (York, Mont.); 704 (Slim Buttes, S. Dak.); and 757 (Rosebud, S. Dak.).

Book excerpt: Yields for high-survival, unthinned ponderosa pine (Pinus ponderosa Laws.) plantations in northern California are estimated. Stems of 367 trees in 12 plantations were analyzed to produce a growth model simulating stand yields. Diameter, basal area, and net cubic volume yields by Site Indices, 40 through 120 are tabulated for stands ranging in age between 10 and 50 years and in spacing between 6 by 6 and 12 by 12 feet. Tables also show diameter distributions by crown classes and stem volumes in cubic feet for plantation-grown ponderosa pine. These data provide both a standard with which to compare the effects of management decisions, and a performance goal.

Download or read book Growth of Planted Ponderosa Pine Thinned to Different Stocking Levels in Northern California written by William W. Oliver and published by . 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.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Potential production of ponderosa pine in the Southwest is simulated for various combinations of stand density, site index, age, and thinningschedule. Such estimates are needed to project future development of stands managed in different ways.
Download or read book Site Classification of Ponderosa Pine Stands Under Stocking Control in California written by Robert F. Powers and published by . This book was released on 1978 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing systems for estimating site index of ponderosa pine (Pinus ponderosa Laws.) do not apply well to California stands where stocking is controlled. A more suitable system has been developed using trends in natural height growth, derived from stem analyses of dominant trees in California. This site index system produces polymorphic patterns of height development to 80 years of age. Using a second system, site index can be predicted in stands where dominants have reached a breast-height age of at least 4 years but have not attained a height of 20 feet. Accuracy of estimates by this method can be strongly influenced by soil type. Accordingly, a separate equation is presented for stands on soils formed from skeletal schists. Yield tables based on the first system will be issued separately.
