Available in PDF, EPUB and Kindle. Book excerpt: Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?

Download or read book Competing Vegetation in Ponderosa Pine Plantations written by Philip M. McDonald and published by . This book was released on 1989 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planted ponderosa pine (Pinus ponderosa Dougl. ex Laws. var. ponderosa) seedlings in young plantations in California are at a disadvantage compared with competing shrubs, forbs, and grasses. In many instances, roots of competing plants begin expanding and exploiting the soil earlier and in greater numbers, thereby capturing the majority of available resources and lowering pine survival and growth. Competition thresholds or "how much is too much?" are: for treatments where a cleared radius is prescribed, no weeds are acceptable within the space needed for maximum growth of pine seedlings during the establishment period; for treatments involving the entire area, crown cover values of 10 to 30 percent seem to be the level beyond which shrub competition significantly affects pine growth. Methods for preparing the site, which include mechanical and chemical methods, use of fire, and combinations of treatments, show the interaction of site and ensuing vegetation. Techniques for controlling competing vegetation from seed include preventing such plants from getting started by use of preemergent herbicides or mats (collars). To prevent sprouting, hardwood trees and large shrubs can be pushed over, thereby getting the root crown out of the ground, or if still in the soil, grinding it out with a machine. Once present, the effect of weeds from seed can be minimized by grubbing or spraying when young, by grazing plants with cattle or sheep, or by introducing plants of low competitive ability. Once sprouting weeds are present, their effect can be minimized by spraying with chemicals, or if palatable, by grazing with cattle or sheep. Costs range from as low as $10 per acre ($25/ha) for aerially applying herbicides to $711 per acre ($1757/ha) for grinding out tanoak stumps.

Download or read book Ecological Effects of Prescribed Fire Season written by Eric Knapp and published by DIANE Publishing. This book was released on 2010-10 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical and prescribed fire regimes for different regions in the continental U.S. were compared and literature on season of prescribed burning synthesized. In regions and vegetation types where considerable differences in fuel consumption exist among burning seasons, the effects of prescribed fire season appears to be driven more by fire-intensity differences among seasons than by phenology or growth stage of organisms at the time of fire. Where fuel consumption differs little among burning seasons, the effect of phenology or growth stage of organisms is often more apparent, because it is not overwhelmed by fire-intensity differences. Species in ecosystems that evolved with fire appear to be resilient to one or few out-of-season prescribed burns. Illus.
