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.

Available in PDF, EPUB and Kindle. Book excerpt: The dry forests and woodlands of Sub-Saharan Africa are major ecosystems, with a broad range of strong economic and cultural incentives for keeping them intact. However, few people are aware of their importance, compared to tropical rainforests, despite them being home to more than half of the continent's population. This unique book brings together scientific knowledge on this topic from East, West, and Southern Africa and describes the relationships between forests, woodlands, people and their livelihoods. Dry forest is defined as vegetation dominated by woody plants, primarily trees, the canopy of which covers more than 10 per cent of the ground surface, occurring in climates with a dry season of three months or more. This broad definition - wider than those used by many authors - incorporates vegetation types commonly termed woodland, shrubland, thicket, savanna, wooded grassland, as well as dry forest in its strict sense. The book provides a comparative analysis of management experiences from the different geographic regions, emphasizing the need to balance the utilization of dry forests and woodland products between current and future human needs. Further, the book explores the techniques and strategies that can be deployed to improve the management of African dry forests and woodlands for the benefit of all, but more importantly, the communities that live off these vegetation formations. Thus, the book lays a foundation for improving the management of dry forests and woodlands for the wide range of products and services they provide.
Download or read book The Red cockaded Woodpecker written by Richard Conner and published by University of Texas Press. This book was released on 2010-06-28 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though small among its woodpecker relatives, the Red-cockaded Woodpecker poses a huge dilemma for its human neighbors. Uniquely adapted to live in the old-growth pine forests of the southeastern United States, the Red-cockaded Woodpecker has nearly disappeared as the forests have been cleared for agricultural, commercial, and residential uses over the last two centuries. Today, it waits at a crossroads. Scientific management practices could restore the woodpecker's habitat and population, but the imperative to convert old-growth forests to other uses remains. In this book, three of the leading experts on the Red-cockaded Woodpecker offer a comprehensive overview of all that is currently known about its biology and natural history and about the ecology of the fire-maintained forests it requires for survival. As the most visible endangered species in the Southeast, and the one whose conservation impacts the largest land area, the Red-cockaded Woodpecker holds a compelling interest not only for ornithologists, but also for wildlife managers, foresters, developers, environmentalists, and government officials. For all of these groups, this book will be the essential resource for learning more about the Red-cockaded Woodpecker and ensuring its survival.
