Citation: Parks, Sean A.; Holsinger, Lisa M.; Miller, Carol L.; Nelson, Cara R. 2015. Wildland fire as a self-regulating mechanism: the role of previous burns and weather in limiting fire progression. Ecological Applications 25(6):1478-1492.

Summary:

The authors’ objective was to research the ability of wildfire to limit the spread of a subsequent fire based on the time between the two, and also to see how weather at the time of the fire alters this effect.



Citation: O'Connor, Christopher D.; Lynch, Ann M.; Falk, Donald A.; Swetnam, Thomas W. 2015. Post-fire forest dynamics and climate variability affect spatial and temporal properties of spruce beetle outbreaks on a Sky Island mountain range. Forest Ecology and Management 336:148-162.

Summary:

The authors reconstructed the species composition and structure of Engelmann spruce forest stand populations over a 319-year period between stand-replacing fire to determine how changes in the stand structure of spruce over time affect the size and severity of spruce beetle outbreaks.



Citation: Abella, Scott R.; Fornwalt, Paula J. 2015. Ten years of vegetation assembly after a North American mega-fire. Global Change Biology 21(2):789-802.

Summary:

This paper examines the post-fire recovery, resistance and resilience, of understory vegetation after a mega fire along a gradient of fire severities.



Citation: Shive, Kristen L.; Fulé, Peter Z.; Sieg, Carolyn Hull; Strom, Barbara A.; Hunter, Molly E. 2014. Managing burned landscapes: evaluating future management strategies for resilient forests under a warming climate. International Journal of Wildland Fire 23(7):915-928.

Summary:

Using the Forest Vegetation Simulator (FVS), the authors examined the effects of projected climate scenarios on future forest trajectories of ponderosa pine ecosystems in the Rodeo-Chediski Fire, and they further examined the potential effects of management strategies, including prescribed fire, to mitigate climate effects and increase resilience.



Citation: O'Connor, Christopher D.; Falk, Donald A.; Lynch, Ann M.; Swetnam, Thomas W. 2014. Fire severity, size, and climate associations diverge from historical precedent along an ecological gradient in the Pinaleño Mountains, Arizona, USA. Forest Ecology and Management 329:264-278.

Summary:

The authors reconstructed the fire regime before and after fire exclusion around approximately 1880 to determine if recent large, high-severity fire is within the natural range of variability for Sky Island ecosystems in the Pinaleño Mountains of Arizona, U.S.



Citation: Tarancón, Alicia Azpeleta; Fulé, Peter Z.; Shive, Kristen L.; Sieg, Carolyn Hull; Sánchez Meador, Andrew; Strom, Barbara A. 2014. Simulating post-wildfire forest trajectories under alternative climate and management scenarios. Ecological Applications 24(7):1626-1637.

Summary:

The authors assessed potential future trajectories of forest stand structure in treated and untreated sites within the Rodeo-Chediski fire in response to multiple scenarios of climate change using the Climate-Forest Vegetation Simulator (FVS).



Citation: Waltz, Amy E. M.; Stoddard, Michael T.; Kalies, Elizabeth L.; Springer, Judith D.; Huffman, David W.; Sánchez Meador, Andrew. 2014. Effectiveness of fuel reduction treatments: assessing metrics of forest resiliency and wildfire severity after the Wallow Fire, AZ. Forest Ecology and Management 334:43-52.

Summary:

The authors compared treated and untreated areas after the 2011 Wallow Fire to assess if fuel treatments reduced fire severity and increased ecological resiliency of mixed-conifer forests based on three metrics: high severity patch size, tree survivorship, and nonnative/native herbaceous understory cover post-fire.



Citation: Hoff, Valentijn; Teske, Casey C.; Riddering, James P.; Queen, Lloyd P.; Gdula, Eric G.; Bunn, Windy A. 2014. Changes in severity distribution after subsequent fires on the North Rim of Grand Canyon National Park, Arizona, USA. Fire Ecology 10(2):48-63.

Summary:

The authors examined the effects of initial fire severity on subsequent fire severity and also how the pattern of burn severity patches is affected by initial burn conditions.



Citation: Parks, Sean A.; Miller, Carol L.; Nelson, Cara R.; Holden, Zachary A. 2014. Previous fires moderate burn severity of subsequent wildland fires in two large western US wilderness areas. Ecosystems 17(1):29-42.

Summary:

The authors examined fire-on-fire interactions in two wilderness areas to determine the extent to which a wildfire can influence the severity of a subsequent fire and, if so, how long does the effect last. They also looked at the influence of topography and vegetation on burn severity of reburned areas.



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.
