Western US ponderosa pine forests have recently suffered extensive stand-replacing fires followed by hillslope erosion and sedimentation. These fires are usually attributed to increased stand density as a result of fire suppression, grazing and other land use, and are often considered uncharacteristic or unprecedented. Tree-ring records from the past 500 years indicate that before Euro-American settlement, frequent, low-severity fires maintained open stands. However, the pre-settlement period… 
Long-term fire history from alluvial fan sediments: the role of drought and climate variability, and implications for management of Rocky Mountain forests
Alluvial fan deposits are widespread and preserve millennial-length records of fire. We used these records to examine changes in fire regimes over the last 2000 years in Yellowstone National Park
Holocene fire-related alluvial-fan deposition and climate in ponderosa pine and mixed-conifer forests, Sacramento Mountains, New Mexico, USA
We employed 14C dating of alluvial-fan deposits in ponderosa pine and mixed-conifer forests of the Sacramento Mountains, New Mexico to document Holocene fires and related geomorphic impacts. Rapid
Vegetative and climatic controls on Holocene wildfire and erosion recorded in alluvial fans of the Middle Fork Salmon River, Idaho
The Middle Fork Salmon River watershed spans high-elevation mixed-conifer forests to lower-elevation shrub-steppe. In recent decades, runoff from severely burned hillslopes has generated large debris
The Holocene record of fire and erosion in the southern Sacramento Mountains and its relation to climate
As highlighted in this issue’s Gallery of Geology on page 24, large, severe wildfires have become part of the New Mexico late spring and early summer experience in the last few decades. Such fires
Historical forest structure and fire in Sierran mixed-conifer forests reconstructed from General Land Office survey data
Dry forests of the western United States (ponderosa pine, dry mixed conifer) are often considered at risk of uncharacteristic severe fires, but recent research has found historically extensive severe
Late Holocene Relationships Among Fire , Climate , and Vegetation in Rangeland Ecosystems of Southwestern Idaho
Rangelands are characterized by more arid climates than forested regions; therefore, establishing fire histories using traditional methods (e.g. fire-scars from trees or charcoal in lake sediments)
Examining Historical and Current Mixed-Severity Fire Regimes in Ponderosa Pine and Mixed-Conifer Forests of Western North America
The findings suggest that ecological management goals that incorporate successional diversity created by fire may support characteristic biodiversity, whereas current attempts to “restore” forests to open, low-severity fire conditions may not align with historical reference conditions in most ponderosa pine and mixed-conifer forests of western North America.


Nonequilibrium Dynamics between Catastrophic Disturbances and Old‐Growth Forests in Ponderosa Pine Landscapes of the Black Hills
An emerging goal of ecosystem management is to maintain ecosystems within their range of natural variability, which requires attention to pre‐EuroAmerican landscape‐scale processes and corresponding
Climatic and human influences on fire regimes in ponderosa pine forests in the Colorado Front Range.
In the northern Colorado Front Range, fire suppression during the 20th cen- tury is believed to have created a high hazard of catastrophic fire in ponderosa.pine (Pinus ponderosa) forests. Since the
Fire Regimes on Andesitic Mountain Terrain in Northeastern Yellowstone-National-Park, Wyoming
A fire history investigation was conducted for three forest community types in the Absaroka Mountains of Yellowstone National Park, Wyoming. Master fire chronologies were based on fire-initiated age
Long-term, landscape patterns of past fire events in a montane ponderosa pine forest of central Colorado
Parameters of fire regimes, including fire frequency, spatial extent of burned areas, fire severity, and season of fire occurrence, influence vegetation patterns over multiple scales. In this study,
Fire and alluvial chronology in Yellowstone National Park: Climatic and intrinsic controls on Holocene geomorphic processes
We employed a systemwide approach, a large and robust set of radiocarbon ages, and modern process analogs to interpret the Holocene history of forest fire–related sedimentation and overall alluvial
Fire, storms, and erosional events in the Idaho batholith
In late December 1996, the South Fork Payette River basin in west‐central Idaho experienced a prolonged storm that culminated on January 1, 1997, with intense rain on melting snow that triggered
The variability of root cohesion as an influence on shallow landslide susceptibility in the Oregon Coast Range
Decades of quantitative measurement indicate that roots can mechanically reinforce shallow soils in forested landscapes. Forests, however, have variations in vegetation species and age which can
Landscape-scale controls over 20th century fire occurrence in two large Rocky Mountain (USA) wilderness areas
Topography, vegetation, and climate act together to determine thespatial patterns of fires at landscape scales. Knowledge oflandscape-fire-climate relations at these broad scales (1,000s hato
