    This study, initiated in , evaluates the effects of thinning and burning treatments in fire-adapted ponderosa pine-mixed conifer forests. Participants discussed short and mid-term treatment effects, including stand dynamics, fuel treatment longevity, potential fire behavior, bark beetle activity, and soil productivity. and old-growth forests in the Klamath Mountains (USDA– USDI,).Theuseofprescribed fireintheseareasisseenas both a risk and an important management tool for sustaining forest conditions (USDA–USDI, ). The goal of this study was to describe the fire history in a ponderosa pine mixed-conifer forest in the southeastern.

      We propose an month project to develop an integrated synthesis that provides forestland managers with comprehensive, up-to-date knowledge on ecological values and options for management of harzardous fuels within ponderosa pine / mixed conifer (PP/MC) forests. PP/MC forests occur throughout the interior West, the Sierra Nevada, Cascade Range, .   Stand-level forest structure varies spatially and surface fuels would be expected to vary as well. We measured surface fuel deposition and decomposition within old-growth Jeffery pine (Pinus jeffreyi Balf.)-mixed conifer forests to quantify rates of change and examine relationships with overstory structure and composition. Annual fuel deposition ranged from Cited by: 2.

    In addition, on those sites where ponderosa pine is dominant, portions of other montane forests (Küchler ), and Pacific ponderosa pine-Douglas-fir (Barbour ), and mixed conifer (, ), (Eyre ) are included in ponderosa pine habitat. We measured surface fuel deposition and decomposition within old-growth Jeffery pine (Pinus jeffreyi Balf.)-mixed conifer forests to quantify rates of change and examine relationships with overstory structure and composition. Results: Annual fuel deposition ranged from to Mg ha−1 for litter and to Mg ha−1 for woody fuels.

Rocky Mountain Forest and Cited by: Estimates for fuel loads in pre-settlement ponderosa pine forests are limited.

However, Covington and Moore (b) estimate that forest floor and woody fuel loadings on North Kaibab ponderosa pine forests were less than Mg/ha (1 ton/acre).

Fuels loads and climate were the driving force for pre-settlement fires in ponderosa pine : Michael A. Battaglia, Wayne D. Shepperd. The ponderosa pine ecosystems of the West have change dramatically since Euro-American settlement years ago due to past land uses and the curtailment of natural fire.

Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increasedCited by: The ponderosa pine (Pinus ponderosae scopulorum) is the most widely distributed pine in North America and occupies a vast area in the West.

Ponderosa pine forests, woodlands and savannas occupy approximately 2 million acres in Colorado or 8 percent of the state’s forested land.

We will produce a guide to fuel treatment practices for ponderosa pine/jeffrey pine and ponderosa pine/mixed conifer forests in California and the Southwest by reviewing the existing literature, interviewing land managers.

Ponderosa Pine Forest is the lowest-elevation, most extensive forest in the American Southwest. It occurs in an elevational band below Mixed Conifer Forest and above Pinyon-Juniper vegetation, Gambel Oak Shrubland, and Interior Chaparral : John L.

Vankat. In the lower-elevation sequoia-mixed-conifer and ponderosa pine forests, however, a considerable fire hazard has built up because of the exclusion of natural fire during the past half century or more (Leopold et al., ; Biswell et al., ). What may have once been natural crown-fire immunity has now been lost.
