Available in PDF, EPUB and Kindle. Book excerpt: Among the many challenges land managers face in implementing restoration projects, one of the greatest is the difficulty of integrating restoration with other management imperatives. One of the most significant of those is the need to manage natural areas for the conservation of native animal and plant species. Some species are popular for hunting and wildlife watching; many serve vital ecological roles; many are rare and under special legal protection. It is not always clear if their habitat needs are compatible with restoring ecological integrity across the landscape. Yet there is evidence that ecological restoration can overlap to a large degree with the priorities of conservation biology. In 2004 the Ecological Restoration Institute sponsored two workshops aimed at exploring this issue.
Download or read book Establishing Reference Conditions for Southwestern Ponderosa Pine Forests written by Peter Friederici and published by . This book was released on 2004 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Restoration treatments that include prescribed burning, often preceded by thinning to reduce fuel loads, have the potential to improve the ecological health of these forests. In order to wisely set the goals that underlie these treatments, it is useful for us to know as much as possible about past forest conditions, especially the reference conditions that existed before forest structure and function were altered by Euro-American settlers. They formed the evolutionary environment of southwestern ponderosa pine trees a fairly stable environment, in other words, in which this tree species and many other plants and animals evolved and adapted. Restoring conditions similar to those of the evolutionary environment is not a matter of trying to return to the past; rather, it is only a way to assure the long-term health of these forests into the future.

Download or read book Restoring Spatial Pattern to Southwestern Ponderosa Pine Forests written by Dave Egan and published by . This book was released on 2008 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, forest managers have largely ignored the value of maintaining dynamic spatial patterns in forested ecosystems. In the America Southwest, where the norm in overstocked forests that are extremely susceptible to catastrophic fires and/or insect infestations and disease, restoring a spatial pattern of openings and tree groups would help alleviate these threats and move the forests within their historic range of variability. This ERI working paper focuses on restoring a dynamic spatial pattern to ponderosa pine forests in the American Southwest. It also addresses basic questions that land managers and others have about how to restore active spatial patterns across the forested Southwest.

Available in PDF, EPUB and Kindle. Book excerpt: This Working Paper is one of a series that describes the planning and implementation of restoration treatments in southwestern ponderosa pine forests. In this paper the treatment type is designed to emulate the forest structure prevalent before the landscape-level disturbances that followed Euro-American settlement. It represents the best scientifically based knowledge currently available about treatment types and effects. But this Working Paper is not a prescription. Restoration decisions need to be made with close attention to local conditions there is no one size fits all approach, and specific prescriptions must be determined according to project objectives. Use this publication as an aid in making informed decisions about how to restore more natural conditions, and greater health, to the southwestern ponderosa pine forests.

Download or read book Managing Gambel Oak in Southwestern Ponderosa Pine Forests written by Scott R. Abella and published by . This book was released on 2008 with total page 40 pages. 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 Restoring the Uinkaret Mountains written by and published by . This book was released on 2002 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1995, the Ecological Restoration Institute (ERI) at Northern Arizona University (NAU) has been working with the Bureau of Land Management (BLM) and Arizona Game and Fish Department (AGFD) to implement and monitor large-scale ponderosa pine forest ecosystem restoration in northwest Arizona. This work has already produced many valuable lessons that have been applied to restoration in the Uinkaret Mountains on the Arizona Strip, but many of those lessons may also be useful elsewhere. This document summarizes operational lessons learned during more than five years of intensive research, and suggests how it may be applied at other ponderosa pine restoration sites in the Southwest.
Download or read book Ecology Management and Restoration of Pi on juniper and Ponderosa Pine Ecosystems written by Gerald J. Gottfried and published by . This book was released on 2008 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southwestern piñon-juniper and juniper woodlands cover large areas of Arizona, New Mexico, Utah, and adjacent Colorado. Ponderosa pine forests are the most common timberland in the Southwest. All three ecosystems provide a variety of natural resources and economic benefits to the region. There are different perceptions of desired conditions. Public and private land managers have adapted research results and their observations and experiences to manage these ecosystems for multiresource benefits. Ways to mitigate the threat of wildfires is a major management issue for these ecosystems, and the wide-spread piñon mortality related to drought and the bark beetle infestation has heightened concerns among managers and the general public. In addition, the impacts of climate change on these ecosystems are a growing concern. As a step in bringing research and management together to answer some of these questions, workshops concerned with the ecology, management, and restoration of piñon-juniper and ponderosa pine ecosystems were held in St. George, Utah in 2005 and in Albuquerque, New Mexico in 2006. The combined proceedings from these two workshops contain papers, extended abstracts, and abstracts based on oral and poster presentations. Some topics included forest and woodland restoration treatments and their impacts on fuels, wildlife, and other ecosystem components, watershed management, insect infestations and drought, wood utilization, landscape changes, basic ecology, and more.
Download or read book Identification and Ecology of Old Ponderosa Pine Trees in the Colorado Front Range written by Laurie Stroh Huckaby and published by . This book was released on 2003 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: We describe the distinguishing physical characteristics of old ponderosa pine trees in the Front Range of Colorado, the processes that tend to preserve them, their past and present ecological significance, and their role in ecosystem restoration. Photographs illustrate identifying features of old ponderosa pines and show how to differentiate them from mature and young trees. The publication includes a photographic gallery of old ponderosa pine trees growing on poor, moderate, and good sites. We illustrate trees growing under various forest conditions and with different injuries and histories. We discuss dendrochronological methods of aging old trees and determining their fire history. The companion field guide includes a condensed description of ponderosa pine ecology, distinguishing characteristics of old ponderosa pines, and a photographic gallery illustrating their identifying features.

Book excerpt: Due to logging and other ecological changes, old trees have grown scarce in most southwestern ponderosa pine forests. Many of those that remain are under increased stress due to competition from overcrowded younger trees, as well as from fire and insects. One of the primary aims of forest restoration is to preserve old trees and to reduce competition around younger trees so that they grow large more quickly. This paper explores methods to avoid fire-caused mortality among the older leave trees during a restoration treatment.
