Book Repeated Manual Release in a Young Plantation

Download or read book Repeated Manual Release in a Young Plantation written by Philip M. McDonald and published by . This book was released on 1994 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Douglas-fir seedlings on the Arcata Resource Area, Bureau of Land Management, U.S. Department of the Interior, in central coastal California, were released by chain sawing and grubbing competing vegetation around them at different frequencies (0, 2, and 3 grubbings) over a 5-year period. After 5 years, average Douglas-fir stem diameter (measured at 12 inches above mean groundline) of seedlings grubbed at ages 1,2, and 5 was 0.91 inches, and of seedlings grubbed after the first and fifth growing season was 0.95 inches. Both were significantly larger than counterparts in the control (0.57 inches). Tanoak, the most competitive species, constituted 84 percent of total plant cover in the control after 5 years, but only 25 percent on treated plots. Combined shrubs varied little between the untreated control and treated plots and averaged about 7 percent of total foliar cover. Grasses were not present in the control and only for the fifth year in treated plots. The most abundant forb, a hedge nettle, increased greatly in density in both control and treated plots. These relationships and others denoted in the paper yield valuable ecological information on species and community dynamics in both a natural and treated environment. Crew time (no overhead or travel costs) for the three grubbings was 52 hours and for the two grubbings was 44 hours.

Book The Longleaf Pine Forest

Download or read book The Longleaf Pine Forest written by Kenneth W. Outcalt and published by . This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longleaf pine cornunities were once the most prevalent ecosystem in the Southeastern United States. Conversions of land to agricultural and urban uses and replacement of longleaf with other pine species following logging have drastically reduced the area occupied by longleaf pine. Although longleaf communities can still be found over most of its original range, the species occupies less than 5 percent of its historical acreage, Private individuals own most of the remaining longleaf pine, except in Florida. The private sector is where most losses in longleaf acreage have occurred over the last decade. Because prices and the number of sawtimber-sized trees are increasing, potential harvests in the near future will probably be high. If appropriate information and incentives are not in place, losses of longleaf from private lands could substantially increase.
