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!
