Available in PDF, EPUB and Kindle. Book excerpt: Gambel oak (Quercus gambelii) is a key deciduous species in southwestern ponderosa pine (Pinus ponderosa) forests and is important for wildlife habitat, soil processes, and human values. This report (1) summarizes Gambel oak's biological characteristics and importance in ponderosa pine forests, (2) synthesizes literature on changes in tree densities and fire frequencies since Euro-American settlement in pine-oak forests, (3) suggests management prescriptions for accomplishing various oak management objectives (for example, increasing diameter growth or acorn production), and (4) provides an appendix containing 203 Gambel oak literature citations organized by subject. Nine studies that reconstructed Gambel oak density changes since settlement in the late 1800s reported that densities of small oaks have escalated, with increases ranging from 4- to more than 63-fold. A possible argument for passive oak management, that overall oak abundance has decreased, is not supported by published research. Manipulating oak growth forms is one of the main means for managing oak and ecosystem components affected by oak. Published research has classified variants of three basic oak growth forms: shrubby thickets of small stems, pole-sized clumps, and large trees. Burning and cutting constitute major prescriptions for manipulating these growth forms, whereas pine thinning has most consistently increased oak diameter growth for promoting large oaks. Because of their high ecological value, large, old oaks should be retained in any management prescription. Sufficient research has been published on which to base some oak management prescriptions, but additional research on poorly understood aspects of oak's ecology is needed to refine and improve oak management.
Download or read book The Ecology and Silviculture of Oaks 3rd Edition written by Paul S Johnson and published by CABI. This book was released on 2019-04-10 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third edition of The Ecology and Silviculture of Oaks is an updated and expanded edition that explores oak forests as responsive ecosystems. New chapters emphasize the importance of fire in sustaining and managing oak forests, the effects of a changing climate, and advanced artificial regeneration techniques. This new edition expands on silvicultural methods for restoring and sustaining oak woodlands and savannahs, and on management of ecosystem services, including wildlife habitat. It also incorporates new material on evaluating landscape-scale, and cumulative effects of management action compared with inaction. Nine of the fifteen chapters cover updated information on the geographic distribution of US oaks, oak regeneration dynamics, site productivity, stocking and stand development, even- and uneven-aged silvicultural methods, and growth and yield. This edition includes a new section with colour illustrations for improved visualization of complex relationships. This book is intended for forest and wildlife managers, ecologists, silviculturists, environmentalists, and students of those fields.

Book excerpt: Interest in appropriate management approaches for sustaining longleaf pine (Pinus palustris Mill.) forests has increased substantially during the recent decade. Although long-leaf pine can be managed using even-aged techniques, interest in uneven-aged methods has grown significantly as a result of concern for sustaining the wide range of ecological values associated with maintaining continuous crown cover in these ecosystems. Indeed, land managers have recently sought to restore and sustain the many habitat attributes upon which numerous at-risk species depend, while simultaneously producing high-quality wood products from longleaf pine forest ecosystems. Although earlier research produced a substantial body of knowledge to guide even-aged management, less is known about application of uneven-aged management methods in longleaf pine forests. Much of this information is yet in the developmental staage. However, managers from the Florida Division of Forestry and Florida National Forests, having a keen interest in applying what is currently known, encouraged scientists of the U.S. Department of Agriculture Forest Service, Southern Research Station and faculty members from the School of Forest Resources and Conservation at the University of Florida to engage in a dialogue that focused on addressing 60 of their key questions concerning uneven-aged management of longleaf pine. This dialogue addresses issues related to (1) methods for converting even-aged to uneven-aged stands, (2) growth and yield, (3) selection harvest techniques, (4) optimum logging practices, (5) effects on red-cockaded woodpeckers (Picoides borealis), (6) prescribed burning approaches, (7) regeneration, (8) optimum stand structure, (9) competition tolerance and release of various seedling age classes, and (10) the viability of interplanting and underplanting.
Download or read book Oak Forest Ecosystems written by William J. McShea and published by JHU Press. This book was released on 2002-02-07 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the demise of the American chestnut, oaks are more vital than ever in the delicate web of relationships that sustains North American wildlife. They form the foundation of many North American ecosystems. Acorns are an important part of the diets of more than 100 species of birds and mammals. Until now, most oak ecosystem research has focused on a variety of disparate factors and approaches. This book aims to provide a foundation for managing oak forests as whole, complex ecosystems.
Download or read book Restoration of Longleaf Pine Ecosystems written by and published by . This book was released on 2005 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longleaf pine (Pinus palustris) ecosystems once occupied 38 million ha in the Southeastern United States, occurring as forests, woodlands, and savannas on a variety of sites ranging from wet flatwoods to xeric sandhills and rocky mountainous ridges. Characterized by an open parklike structure, longleaf pine ecosystems are a product of frequent fires, facilitated by the presence of fallen pine needles and bunchgrasses in the understory. Timber harvest, land conversion to agricultural and other nonforest uses, and alteration of fire regimes greatly reduced longleaf pine ecosystems, until only 1.2 million ha remained in 1995. Longleaf pine ecosystems are among the most species-rich ecosystems outside the tropics. However, habitat loss and degradation have caused increased rarity of many obligate species. The lack of frequent surface fires and the proliferation of woody plants in the understory and midstory have greatly increased the risk of additional longleaf pine ecosystem losses from catastrophic fire. Because longleaf pine still exists in numerous small fragments throughout its range, it is reasonable to conclude that it can be restored. Restoration efforts now underway use physical, chemical, and pyric methods to reestablish the natural structure and function in these ecosystems by adjusting species composition, modifying stand structure, and facilitating ecological processes, such as periodic fire and longleaf pine regeneration. The ecological, economic, and social benefits of restoring longleaf pine ecosystems include (1) expanding the habitat available to aid in the recovery of numerous imperiled species, (2) improving habitat quality for many wildlife species, (3) producing greater amounts of high-quality longleaf pine timber products, (4) increasing the production of pine straw, (5) providing new recreational opportunities, (6) preserving natural and cultural legacies, and (7) creating a broader range of management options for future generations.

This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The synthesis presented in this volume is a direct outgrowth of our ten-year FORMAP Project (Forest Mapping Across Eastern North America from 20,000 yr B.P. to the Present). Many previous research efforts in paleoecology have used plant-fossil evidence as proxy information for primarily geologic or climatic reconstructions or as a bio stratigraphic basis for correlation of regional events. In contrast, in this book, we deal with ecological questions that require a holistic perspective that integrates the interactions of biota with their dynamically changing environments over time scales up to tens of thousands of years. In the FORMAP Project, our major research objective has been to use late-Quaternary plant-ecological data sets to evaluate long-term patterns and processes in forest de velopment. In order to accomplish this objective, we have prepared subcontinent-scale calibrations that quantitatively relate the production and dispersal of arboreal pollen to dominance in the vegetation for the major tree types of eastern North America. Quantification of pollen-vegetation relationships provides a basis for developing quan titative plant-ecological data sets that allow further ecological analysis of both individual taxa and forest communities through time. Application of these calibrations to fossil pollen records for interpreting forest history thus represents a fundamental step beyond traditional summaries based upon pollen percentages.

Available in PDF, EPUB and Kindle. Book excerpt: The Cary Conferences, as we have envisaged them, are different from most scientific meetings in that they provide a forum for major issues in ecology from a more philosophical point of view. It appears to many of us that ecologists have limited opportunities to come together in small groups to address in a more philosophical way some of the major questions and issues that matter very much to the future of humankind and to us as ecologists. Moreover, we hope that the setting ofthe Mary Flagler Cary Arboretum promotes strong interaction and dis cussion between Conference participants with a minimum of distraction. We are proud to make our facilities available for such meetings, and we hope that over the years these Conferences might provide direction and leadership for the whole field of ecology. We have the broad goal of attempting to advance the field of ecology by bringing together leading ecologists and other scientists to address major issues. The first Cary Conference, in 1985, considered the status and future of ecosystem science. This first Conference was rather loosely structured but was successful in stimulating discussion, ideas, and enthusiasm (Likens et al. , 1987). The goals for this second Cary Conference in 1987 were: 1. to identify the roles of long-term studies in ecology; 2. to identify the options for study of long-term ecological phenomena; 3.
