This book was released on 2013-09-24 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a comprehensive manual of practice for execution of afforestation and tree planting programmes in arid and semi-arid tropics. It includes a compact running account of the technology of afforestation and the relevant principles and practices in management of afforestation projects. It provides a wide range of structured information and a number of model designs which can be gainfully put to use by the field level supervisors as also by the managers concerned with planning and control of such projects. Written by a practising specialist, the book is invaluable for anyone concerned with the practice of afforestation and tree planting, be he a tree hobbyist or a school teacher, a professional forester or a senior policy maker in government, an industrialist or a philanthropist, an environmental activist or a member of a community service organization.

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.

Download or read book Forest Conservation Genetics written by Andrew Young and published by CSIRO PUBLISHING. This book was released on 2000-07-24 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest management must be sustainable not only in ecological, economic and social, but also genetic terms. Many forest managers are advocating and developing management strategies that give priority to conserving genetic diversity within production systems, or that recognise the importance of genetic considerations in achieving sustainable management. Forest Conservation Genetics draws together much previously uncollected information relevant to managing and conserving forests. The content emphasises the importance of conserving genetic diversity in achieving sustainable management. Each chapter is written by a leading expert and has been peer reviewed. Readers without a background in genetics will find the logical sequence of topics allows easy understanding of the principles involved and how those principles may impact on day-to-day forest planning and management decisions. The book is primarily aimed at undergraduate students of biology, ecology, forestry, and graduate students of forest genetics, resource management policy and/or conservation biology. It will prove useful for those teaching courses in these fields and as such help to increase the awareness of genetic factors in conservation and sustainable management, in both temperate and tropical regions.

Available in PDF, EPUB and Kindle. Book excerpt: Tropical climates, which occur between 23°30'N and S latitude (Jacob 1988), encompass a wide variety of plant communities (Hartshorn 1983, 1988), many of which are diverse in their woody floras. Within this geographic region, temperature and the amount and seasonality of rainfall define habitat types (UNESCO 1978). The F AO has estimated that there 1 are about 19 million km of potentially forested area in the global tropics, of which 58% were estimated to still be in closed forest in the mid-1970s (Sommers 1976; UNESCO 1978). Of this potentially forested region, 42% is categorized as dry forest lifezone, 33% is tropical moist forest, and 25% is wet or rain forest (Lugo 1988). The species diversity of these tropical habitats is very high. Raven (1976, in Mooney 1988) estimated that 65% of the 250,000 or more plant species of the earth are found in tropical regions. Of this floristic assemblage, a large fraction are woody species. In the well-collected tropical moist forest of Barro Colorado Island, Panama, 39. 7% (481 of 1212 species) of the native phanerogams are woody, arborescent species (Croat 1978). Another 21. 9% are woody vines and lianas. Southeast Asian Dipterocarp forests may contain 120-200 species of trees per hectare (Whitmore 1984), and recent surveys in upper Amazonia re corded from 89 to 283 woody species ~ 10 cm dbh per hectare (Gentry 1988). Tropical communities thus represent a global woody flora of significant scope.
