Fire History and Forest Structure along an Elevational Gradient in the Southern Cascade Range, Oregon, USA

Authors: Alison B. Forrestel, Robert A. Andrus, Danny L. Fry, and Scott L. Stephens
Pages: 1-15
DOI: 10.4996/fireecology.1301001

We examined stand structure, demography, and fire history using tree cores and fire scar data across an approximately 7000-hectare study area over an elevational gradient in the southern Cascade Range, Oregon, USA. Our plots were located in mountain hemlock (Tsuga mertensiana [Bong.] Carr), red fir (Abies magnifica A. Murr.), lodgepole pine (Pinus contorta Loudon), and mixed conifer forest types.

The Influence of Western Spruce Budworm on Fire in Spruce-Fir Forests

Authors: Eric Vane, Kristen M. Waring, and Adam Polinko
Pages: 16-33
DOI: 10.4996/fireecology.1301016

Western spruce budworm (Choristoneura freemani Razowski; WSBW) is the most significant defoliator of coniferous trees in the western United States. Despite its important influence on Western forests, there are still gaps in our knowledge of WSBW’s impact on fire, and little research has been done on this relationship in high-elevation spruce-fir forests.

Carbon Emissions during Wildland Fire an a North American Temperate Peatland

Authors: Robert A. Mickler, David P. Welch, and Andrew D. Bailey
Pages: 34-57
DOI: 10.4996/fireecology.1301034

Northern temperate zone (30° to 50° latitude) peatlands store a large proportion of the world’s terrestrial carbon (C) and are subject to high-intensity, stand-replacing wildfires characterized by flaming stage combustion of aboveground vegetation and long-duration smoldering stage combustion of organic soils. Coastal peatlands are a unique region in which long-duration wildfire soil combustion is responsible for the majority of total annual emissions from all wildfires in the North American coastal plain.

Corroborating Evidence of a Pre-Euro-American Low- to Moderate-Severity Fire Regime in Yellow Pine–Mixed Conifer Forests of the Sierra Nevada, California, USA

Authors: Jay D. Miller and Hugh D. Safford
Pages: 58-90
DOI: 10.4996/fireecology.1301058

Fire was the dominant ecological process controlling forest structure and succession in western North American conifer forests for thousands of years. Because fires are now suppressed, and because widespread logging has greatly altered vegetation structure, land managers often use estimates of pre-Euro-American settlement forest conditions to help guide restoration actions. It follows that it is important to fully understand the characteristics of pre-Euro-American settlement fire regimes.

Resilience of California Black Oak Experiencing Frequent Fire: Regeneration following Two Large Wildfires 12 Years Apart

Authors: Ethan J. Hammett, Martin W. Ritchie, and John-Pascal Berrill
Pages: 91-103
DOI: 10.4996/fireecology.1301091

Historically, oak woodlands in western North America were maintained by frequent fire that killed competing conifers. Today, these woodlands are often in decline as competition from conifers intensifies. Among oak species affected is the ecologically important California black oak (Quercus kelloggii Newberry). Within its range, large high-severity wildfires have become more common.

Shrub Communities, Spatial Patterns, and Shrub-Mediated Tree Mortality following Reintroduced Fire in Yosemite National Park, California, USA

Authors: James A. Lutz, Tucker J. Furniss, Sara J. Germain, Kendall M.L. Becker, Erika M. Blomdahl, Sean M.A. Jeronimo, C. Alina Cansler, James A. Freund, Mark E. Swanson, and Andrew J. Larson
Pages: 104-126
DOI: 10.4996/fireecology.1301104

Shrubs contribute to the forest fuel load; their distribution is important to tree mortality and regeneration, and vertebrate occupancy. We used a method new to fire ecologyextensive continuous mapping of trees and shrub patches within a single large (25.6 ha) study siteto identify changes in shrub area, biomass, and spatial pattern due to fire reintroduction by a backfire following a century of fire exclusion in lower montane forests of the Sierra Nevada, California, USA.

The Effects of Fire and Manual Biomass Removal on the Vegetation of Granite Inselbergs

Author: John T. Hunter
Pages: 127-137
DOI: 10.4996/fireecology.1301127

The vegetation on granite inselbergs (island mountains) within the New England Bioregion of eastern Australia and the adjacent matrix were chosen as subjects in this study on the effects of aboveground biomass removal on community recovery. Undisturbed inselberg vegetation was treated by manual removal of biomass through clipping and also by burning. Inselbergs and the adjacent matrix that had been burned the previous year were also treated to an additional burn.

Smoke Water and Heat Influence Emergence of Shortgrass Prairie Species

Authors: Robert D. Cox, Yi-Fang Chou, and David B. Wester
Pages: 138-148
DOI: 10.4996/fireecology.1301138

Exposure to smoke can influence the germination of seeds in many fire-prone ecosystems, but this effect is not well studied in grasslands. Smoke treatments such as smoke water could be useful as management and restoration tools if the response of target species in natural settings is well understood. We tested eight species native to the southern High Plains region in Texas, USA, that were already known to respond to smoke water in the laboratory, for their responses in a less controlled glasshouse environment.

Prescribed Burning in Ponderosa Pine: Fuel Reductions and Redistributing Fuels near Boles to Prevent Injury

Authors: Robert A. Progar, Kathryn H. Hrinkevich, Edward S. Clark, and Matthew J. Rinella
Pages: 149-161
DOI: 10.4996/fireecology.1301149

Fire suppression and other factors have resulted in high wildfire risk in the western US, and prescribed burning can be an effective tool for thinning forests and reducing fuels to lessen wildfire risks. However, prescribed burning sometimes fails to substantially reduce fuels and sometimes damages and kills valuable, large trees. This study compared fuel reductions between spring and fall prescribed burns and tested whether removing (i.e., raking) fuels within 1 m of boles reduced fire damage to ponderosa pine (Pinus ponderosa Douglas ex Lawson & C. Lawson).
