Citation: Amato, Victoria J.W.; Lightfoot, David; Stropki, Cody L.; Pease, Michael. 2013. Relationships between tree stand density and burn severity as measured by the Composite Burn Index following a ponderosa pine forest wildfire in the American Southwest. Forest Ecology and Management 302:71-84.

Summary:

The authors assessed the relationship between fire severity and stand density using the composite burn index (CBI).



Citation: Larson, Andrew J.; Belote, R. Travis; Cansler, C. Alina; Parks, Sean A.; Dietz, Matthew S. 2013. Latent resilience in ponderosa pine forest: effects of resumed frequent fire. Ecological Applications 23(6):1243-1249.

Summary:

The authors quantified the effects of reintroducing fire to an unlogged, fire?excluded, ponderosa pine forest to examine post-fire trajectories of forest regeneration and stand composition and structure and to see if ponderosa pine forests possess latent resilience to reintroduced fire.



Citation: Shive, Kristen L.; Sieg, Carolyn H.; Fulé, Peter Z. 2013. Pre-wildfire management treatments interact with fire severity to have lasting effects on post-wildfire vegetation response. Forest Ecology and Management 297:75-83.

Summary:

The authors sampled plots eight years post-wildfire that had been thinned and burned under prescription prior to the Rodeo-Chediski fire to examine differences between areas that burned at high and low severity with or without treatments pre-fire. They specifically examined post-fire species composition, exotic species response, and ponderosa pine regeneration.



Citation: Haire, Sandra L.; McGarigal, Kevin; Miller, Carol. 2013. Wilderness shapes contemporary fire size distributions across landscapes of the western United States. Ecosphere 4(1):1-20.

Summary:

The authors modeled the effects of wilderness on the fire size distribution along forest gradients, while accounting for the effects of topography, weather, and climate.



Citation: Williams, Mark A.; Baker, William L. 2013. Variability of historical forest structure and fire across ponderosa pine landscapes of the Coconino Plateau and south rim of Grand Canyon National Park, Arizona, USA. Landscape Ecology 28(2):297-310.

Summary:

The authors examined ponderosa pine stands using historic General Land Office (GLO) land survey data to reconstruct forest structure and fire regimes of pre-widespread European settlement on the Coconino Plateau and Grand Canyon National Park.



Citation: van Mantgem, Phillip J.; Nesmith, Jonathan C.B.; Keifer, MaryBeth J.; Knapp, Eric E.; Flint, Alan L.; Flint, Lorraine E. 2013. Climatic stress increases forest fire severity across the western United States. Ecology Letters 16(9):1151-1156.

Summary:

The authors examined the relationship between climate and fire severity across coniferous forests of the western U.S.



Citation: Feddema, Johannes J.; Mast, Joy Nystrom; Savage, Melissa. 2013. Modeling high-severity fire, drought and climate change impacts on ponderosa pine regeneration. Ecological Modelling 253:56-69.

Summary:

The authors modeled the effects of drought on ponderosa pine regeneration in high-severity fire areas using a water balance methodology that assess thermal and moisture conditions at the project sites. They validated their model at five regenerating ponderosa pine stands in the Southwest that burned at high-severity during the drought years 1945 to 1956.



Citation: Stevens-Rumann, Camille S.; Shive, Kristen L.; Fulé, Peter Z.; Sieg, Carolyn Hull. 2013. Pre-wildfire fuel reduction treatments result in more resilient forest structure a decade after wildfire. International Journal of Wildland Fire 22(8):1108-1117.

Summary:

The authors compared treated and untreated areas nine years after the 2002 Rodeo-Chediski Fire to assess how stand structure and surface fuels change over longer periods of time. They further compared this information to a previous study (Strom and Fulé, 2007) that installed the study plots in 2004 to assess the differences between short- and longer-term fuel responses.



Citation: Huffman, David W.; Crouse, Joseph E.; Chancellor, W. Walker; Fulé, Peter Z. 2012. Influence of time since fire on pinyon-juniper woodland structure. Forest Ecology and Management 274:29-37.

Summary:

The authors studied the effects of time since fire on the structural development of regeneration and complexity in pinyon-juniper woodlands along a long-term chronosequence of ~370 years.



Citation: Cortés-Montaño, Citlali; Fulé, Peter Z.; Falk, Donald A.; Villanueva-Díaz, José; Yocom, Larissa L. 2012. Linking old-growth forest composition, structure, fire history, climate and land-use in the mountains of northern México. Ecosphere 3(11):art106.

Summary:

The authors quantified the structure and composition of old-growth conifer forest stands in northwestern Mexico. They related this information to fire regime history data from Fulé et al. (2012) to determine relationships between regional climate variability, fire and forest structure since approximately 250 years ago to today.
