Download or read book Restoration of Ponderosa Pine Forests to Presettlement Conditions written by Peter Friederici and published by . This book was released on 2005 with total page 12 pages. 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.

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.

Book excerpt: Brings together the writings of practitioners and thinkers from a variety of fields--including forestry, biology, philosophy, ecology, political science, archaeology, botany, and geography--to synthesize what is known about ecological restoration in ponderosa pine forests and to consider the factors involved in developing and implementing a successful restoration effort.
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.

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 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.
Download or read book Changes in Ponderosa Pine Forests of the Mt Logan Wilderness written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ponderosa pine forests in the Mt. Logan Wilderness on the Arizona Strip have become dense with young trees and highly susceptible to catastrophic wildfire due to exclusion of the natural frequent-fire regime and the effects of livestock grazing and logging associated with Euro-American land use practices. As part of a broader regional ecological restoration study, the Mt. Logan Wilderness was sampled for fire scarred trees, vegetation, and fuels between 1995 and 1997. Reconstructed fire histories show that fires recurred about every 5-6 years prior to settlement, with larger fires burning every 9-12 years. Frequent fires ceased after 1869-1879 in the Mt. Logan Wilderness, coincident with the time of Euro-American settlement, beginning a fire-free period that has lasted up to the present except for a few fires in the 1930s. Current forests are dense, ranging from approximately 700 to 3,000 trees/ha, and dominated by small trees. At both unthinned and thinned sites on basalt soils within the wilderness, tree canopy cover is over 50% and tree basal area is high, 39-40 m2/ha. Understory cover and species diversity are generally low, but slightly higher on cinder soils where shrubs form an important understory community and where tree density is somewhat reduced. Living and dead fuels, including plants, woody debris, and the forest floor, will easily support high-intensity wildfires. In contrast, the presettlement forest was relatively open, with tree densities ranging from approximately 80-100 trees/ha and basal areas ranging from 10-15 m2/ha, dominated by large ponderosa pine trees. In ecological terms, prospects are good for restoring the Mt. Logan Wilderness to emulate the ecological structure and fire disturbance regime of the presettlement reference condition. The current forest is similar to nearby ecosystems where thinning, burning, and fuel treatments are being implemented. However, ecological information is only one component contributing to the debate over appropriate management values and practices in wilderness areas on public lands.
