Identification and Ecology of Old Ponderosa Pine Trees in the Colorado Front Range by Laurie Stroh Huckaby Pdf
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.
For hundreds of years, the massive ponderosa pine of the U.S. Southwest has left multitudes in awe. After spending nearly three decades researching among these trees, Sylvester Allred shares his wealth of experience in the southwestern ponderosa pine forests with the world in Ponderosa. Ponderosa is the first of its kind to provide an introduction to the natural and human histories of the ponderosa pine forests of the Southwest that is accessible to all who wish to enjoy the forests. The book offers knowledge on elemental aspects of the forests, such as the structure of the trees, as well as theoretical perspectives on issues such as climate change. Included are discussions of biogeography, ecology, and human and natural history, illustrated by over fifty color photographs throughout. Allred presents his observations as if he is recalling his thoughts over the course of a walk in a ponderosa pine forest. His imagery-saturated prose provides an informal and enjoyable approach to discovering the history and environment of the ponderosa pine. Using a concise, straightforward writing style, Allred invites readers to explore the forests with him. Ponderosa includes: More than 50 color photos Learn how to estimate the age of a tree See the reptiles, birds, and mammals that make their home in ponderosa pine forests Much more!

Opportunities for Making Wood Products from Small Diameter Trees in Colorado by Dennis Lee Lynch Pdf
Colorado's forests are at risk to forest health problems and catastrophic fire. Forest areas at high risk to catastrophic fire, commonly referred to as Red Zones, contain 2.4 million acres in the Colorado Front Range and 6.3 million acres Statewide. The increasing frequency, size, and intensity of recent forest fires have prompted large appropriations of Federal funds to reduce fire risk and improve fire protection. Experimental ecological restoration studies using thinning and prescribed fire have been conducted at several locations across the State during the past 5 years to determine if high-risk areas could be treated to improve forest health and reduce the potential for catastrophic fires. These studies established that 80 to 96 percent of the trees removed to improve ecological conditions were between 5 and 11.9 inches in diameter. Some trees 12 inches and larger in diameter had to be removed to properly apply ecological prescriptions and typically comprised 4 to 18 percent of the trees removed. The projects studied had profit margins of 1 percent (Pines Partnership), 6 percent (Mixed Conifer Project), a loss of $78,000 (Chessman Reservoir-Trumbull Project), and required subsidies of $779 per acre (Fox Run) and $679 per acre (Air Force Academy). A search for opportunities to use small diameter trees from these projects was conducted as part of an effort to improve the financial feasibility of forest restoration. A previous study, "Wood Use in Colorado at the Turn of the Century" (Lynch and Mackes 2001), describes in detail the various types and quantities of wood products used in the State and identifies where products came from. Using this study, the authors identified potential products that might be manufactured from small diameter trees removed in restoration thinnings. The potential opportunities for using wood are listed in two categories: (1) existing products, processes, and technology, and (2) new products, processes, and technology. Products are arranged within each category in order of increasing complexity of processing and technology. Estimates of the potential retail market value for each product are presented. Examples of existing product opportunities include Christmas trees, mine props, firewood, posts and poles, rough sawn lumber and timbers, and oriented strandboard. Examples of new products and processes include structural roundwood, biomass energy, and wood pulp. The report concludes that future restoration programs must be designed to provide a consistent supply of raw material to processors. It also recognizes that there is no single product that will utilize all small diameter trees from Red Zone areas. Instead, a stable, diverse wood industry appears to be the most desirable future.
A troubling story of the devastating and compounding effects of climate change in the Western and Rocky Mountain states, told through in–depth reportage and conversations with ecologists, professional forest managers, park service scientists, burn boss, activists, and more. Climate change manifests in many ways across North America, but few as dramatic as the attacks on our western pine forests. In Trees in Trouble, Daniel Mathews tells the urgent story of this loss, accompanying burn crews and forest ecologists as they study the myriad risk factors and refine techniques for saving this important, limited resource. Mathews transports the reader from the exquisitely aromatic haze of ponderosa and Jeffrey pine groves to the fantastic gnarls and whorls of five–thousand–year–old bristlecone pines, from genetic test nurseries where white pine seedlings are deliberately infected with their mortal enemy to the hottest megafire sites and neighborhoods leveled by fire tornadoes or ember blizzards. Scrupulously researched, Trees in Trouble not only explores the devastating ripple effects of climate change, but also introduces us to the people devoting their lives to saving our forests. Mathews also offers hope: a new approach to managing western pine forests is underway. Trees in Trouble explores how we might succeed in sustaining our forests through the challenging transition to a new environment.
Cascading Effects of Fire Exclusion in Rocky Mountain Ecosystems by Robert E. Keane Pdf
The health of many Rocky Mountain ecosystems is in decline because of the policy of excluding fire in the management of these ecosystems. Fire exclusion has actually made it more difficult to fight fires, and this poses greater risks to the people who fight fires and for those who live in and around Rocky Mountain forests and rangelands. This paper discusses the extent of fire exclusion in the Rocky Mountains, then details the diverse and cascading effects of suppressing fires in the Rocky Mountain landscape by spatial scale, characteristic, and vegetation type. Also discussed are the varied effects of fire exclusion on some important, keystone ecosystems and human concerns.
Silviculture of Southwestern Ponderosa Pine by Gilbert Herman Schubert Pdf
Describes the status of our knowledge of ponderosa pine silviculture in the southwestern States of Arizona, Colorado, New Mexico, and Utah. Economic value, impact on other uses, and the timber resource are discussed first, followed by ecological background, site quality, growth and yield, and silviculture and management. Relevant literature is discussed along with observations, experience, and results of unpublished research. Treatise is intended to serve as a reference tool for guidance in making management decisions and prescribing silvicultural treatments. Research needs are also considered.
