Book excerpt: Excerpt from Site Treatments Influence Development of a Young-Mixed Species Western Larch Stand Polk and Boe (1951) and Roe (1955) concluded that desired composition of the future stand can neither be attained nor maintained through cutting method alone; seedbed preparation and later stand improvement prae tices are necessary. Specifically, practices are required that obtain establishment of desired tree species before shrubs and other vegetation overwhelm the site. Roe (1955) studied the relative need for sunlight and minera soil seedbeds of larch and its common associates in the western larch type at Terrace Hill on the Coram Experimental Forest in northwestern Montana. He described the relationships among method of cutting, proportion of ground surface in favorable seedbed, and resultant stocking percentages of each species. Schmidt (1969) later reported on seedling and early sapling development and concluded that site preparation - in the form of mechanical scarification, prescribed burning, and slashing of competing shrubs influenced not only regeneration establishment, but sub sequent seedling development. He found, after 12 to 15 years, that larch regenerated abundantly, grew rapidly, and became dominant where prescribed burnin or mechanical scarification provided a sufficient area of ash or mineral soil seedbeds and reduced the amount of competing vegetation. Spruce seedlings also required mineral soil for successful establishment but grew slow] on the exposed seedbeds favored by larch. In contrast. Douglas-fir was insensitive to seedbed condition in the regeneration phase, but tended to dominate the stands where seedbeds had little or no preparation and larch competition was light.

This book was released on 2018-03-30 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Growth of Young Even-Aged Western Larch Stands After Thinning in Eastern Oregon Although utilization of this species is increasing, there is little growth and yield information available from managed stands to aid the forest manager in thinning operations in pole-sized stands. In 1966, a study designed to provide basic information on the response of pure even - aged larch stands to a wide range of stocking levels was begun in northeastern Oregon. This interim report covers the first 5 - year period of the study. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2018-10-07 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Levels-of-Growing-Stock Study in Thinned Western Larch Pole Stands in Eastern Oregon In terms of timber management, the primary factor influencing the residual stocking level is the forester's estimate of the minimum size tree that will be merchantable in the future. The larger the trees must be to support a commercial thinning, the fewer trees should be left after precommercial thinning; and conversely, if smaller trees are merchantable, the residual stocking should be higher. Western larch (larix occidentalis Nutt.) is a valuable seral species in the mixed conifer forests of north eastern Oregon because of its fast growth rate and desirable wood proper ties. Even-aged larch stands generally become established following fire or other forest disturbances. These stands are often heavily overstocked as seedlings. Stand density control by thinning is an essential part of the management of young larch stands. Because of the shade intolerance of larch, tree crowns in unthinned stands are reduced in size resulting in a decrease in rates of diameter and height growth as early as 9 years of age (schmidt The increasing utilization of larch and other species and the associated intensification of forest management raises questions regarding suitable stocking level regimes for managed larch stands.

Available in PDF, EPUB and Kindle. Book excerpt: Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

Available in PDF, EPUB and Kindle. Book excerpt: Although the majority of the world’s forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.

Book excerpt: Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.

Download or read book Every Root an Anchor written by R. Bruce Allison and published by Wisconsin Historical Society. This book was released on 2005-04-13 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Every Root an Anchor, writer and arborist R. Bruce Allison celebrates Wisconsin's most significant, unusual, and historic trees. More than one hundred tales introduce us to trees across the state, some remarkable for their size or age, others for their intriguing histories. From magnificent elms to beloved pines to Frank Lloyd Wright's oaks, these trees are woven into our history, contributing to our sense of place. They are anchors for time-honored customs, manifestations of our ideals, and reminders of our lives' most significant events. For this updated edition, Allison revisits the trees' histories and tells us which of these unique landmarks are still standing. He sets forth an environmental message as well, reminding us to recognize our connectedness to trees and to manage our tree resources wisely. As early Wisconsin conservationist Increase Lapham said, "Tree histories increase our love of home and improve our hearts. They deserve to be told and remembered."
