This book was released on 1993 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An 11-year-old ponderosa pine (Pinus ponderosa Dougl. ex Laws. var. ponderosa) plantation in northern California was grazed annually in summer by 600-1150 dry (nonlactating) ewes in an attempt to reduce competing vegetation and increase growth of pine seedlings. The sheep also provided an opportunity to evaluate density and developmental trends in the pine, shrub, grass, thistle, and forb components of the plant community. A manual release and a deer-only treatment provided contrast to the effects of grazing by sheep. In general, stem diameter and foliar cover of ponderosa pines, rarely damaged by sheep or deer, were significantly greater in manually grubbed areas, but only after 8 years. Pines in grazed areas never differed significantly in height, stem diameter, or foliar cover from control areas. Density, cover, and height of deerbrush (Ceanothus integerrimus H. & A,) were generally fewer and lower if grubbed and grazed, but grass and bull thistle (Cirsium vulgare [Savi] Ten.) were larger and more numerous in these treatments. Forb cover was highest in the rubbed treatment. In general, average density, cover, and height of deerbrush, bull thistle, grasses, and forbs did not differ significantly among treatments grazed by deer or sheep suggesting that sheep did not have a deleterious effect on deer in terms of forage availability.

Book excerpt: Silviculture, as an integrative discipline, must combine management skills with scientific and technical knowledge in the management of forests and woodlands. While traditionally, silviculturists worked in fine resolution landscapes, today's practitioner must look at encompassing both larger geographic areas (adjacent stands, watersheds, regions, subregions) and wider objectives (trees as well as wildlife, commodities, recreation, sustainability, biological diversity, air quality, and ecosystem resilience). The 12 papers in this proceedings explore the past, present, and desired future of silviculture's role and practice. Examination of disturbance ecology in ecosystem management includes natural and induced disturbances, and management options. Discussion of desired future conditions includes the importance of understanding the connection between ecological values and social values, as well as historic reference conditions as they relate to creating forest plans. A section on inventory, monitoring, and adaptive management looks at multiresource and multiscale data assessments and temporal continuity; included are design alternatives and a discussion of how to adapt silvicultural prescriptions. Case studies throughout the proceedings help the reader understand the practical applications, the successes, and the need for further work.

Book excerpt: Grazing animals need to be managed in order to accommodate desired results in terms of animal, plant, land and economic responses. Grazing Management, 2nd Edition integrates principles and management techniques that apply to all grazing lands and to all grazing animals. This comprehensive volume provides authoritative review on a wide range of relevant topics: animal nutrition and nutritional balance when fed on different sorts of grazing lands; seasonal variation and limits placed on ecosystems by grazing; the effects of grazing on grazing lands; the various sorts of grazing behaviors; selecting plants and managing grazing lands, as well as many other important topics bearing upon the methods, practises and procedures for properly managing grazing lands and animals. * Animal nutrition and nutritional balance when fed on different sorts of grazing lands * Seasonal variation and limits placed on ecosystems by grazing * The effects of grazing on grazing lands * The various sorts of grazing behaviours * Selecting plants and managing grazing lands
