Citation: Iniguez, Jose M.; Swetnam, Thomas W.; Baisan, Christopher H. 2016. Fire history and moisture influences on historical forest age structure in the sky islands of southern Arizona, USA. Journal of Biogeography 43(1):85-95.

Summary:

The authors examined synchrony of stand age and structure between geographically separated sites, or sky islands, to determine the influence of moisture and/or drought variability versus fire frequency on historic stand development.



Citation: Andrus, Robert A.; Veblen, Thomas T.; Harvey, Brian J.; Hart, Sarah J. 2016. Fire severity unaffected by spruce beetle outbreak in spruce-fir forests in southwestern Colorado. Ecological Applications 26(3):700-711.

Summary:

The authors examined the effects of spruce beetle infestation on fire severity during the drought years of 2012 to 2013.



Citation: Yocom, Larissa L.; Fulé, Peter Z.; Bunn, Windy A.; Gdula, Eric G. 2015. Historical high-severity fire patches in mixed-conifer forests. Canadian Journal of Forest Research 45(11):1587-1596.

Summary:

The authors examined the size of historical high-severity fire in mixed-conifer and aspen stands on the North Rim of Grand Canyon National Park and compared them to present day patches of high severity fire. The further explored historical climate conditions that produced the largest patches of high severity fire prior to Euro-American settlement.



Citation: Hood, Sharon M.; Sala, Anna; Heyerdahl, Emily K.; Boutin, Marion. 2015. Low-severity fire increases tree defense against bark beetle attacks. Ecology 96(7):1846-1855.

Summary:

The authors tested the theory that frequent, low severity wildfire confers a heightened defense response to ponderosa pine against future bark beetle attack.



Citation: Birch, Donovan S.; Morgan, Penelope; Kolden, Crystal A.; Abatzoglou, John T.; Dillon, Gregory K.; Hudak, Andrew T.; Smith, Alistair M. S. 2015. Vegetation, topography and daily weather influenced burn severity in central Idaho and western Montana forests. Ecosphere 6(1):art17.

Summary:

The authors compared the strength or importance value of “bottom-up” controls, such as vegetation and topography to fire danger indices and daily weather variables on fire severity and daily area burned across 42 large forest fires in central Idaho and western Montana using Random Forest models.



Citation: Shryock, Daniel F.; Esque, Todd C.; Chen, Felicia C. 2015. Topography and climate are more important drivers of long-term, post-fire vegetation assembly than time-since-fire in the Sonoran desert, US. Journal of Vegetation Science 26(6):1134-1147.

Summary:

The authors used a chronosequence to evaluate the effects of time-since-fire on post-fire regeneration across a gradient of topography and climate conditions.



Citation: Liu, Zhihua; Wimberly, Michael C. 2015. Climatic and landscape influences on fire regimes from 1984 to 2010 in the western United States. PLoS ONE 10(10):e0140839.

Summary:

The authors examined the effect of climate, topography, vegetation, and human land use on the spatiotemporal patterns of fire occurrence, severity, and size across the western U.S. using boosted regression tree analysis.



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: Ouzts, Jessi; Kolb, Thomas E.; Huffman, David W.; Sánchez Meador, Andrew. 2015. Post-fire ponderosa pine regeneration with and without planting in Arizona and New Mexico. Forest Ecology and Management 354:281-290.

Summary:

The authors measured ponderosa pine seedling recovery of planted and unplanted areas after severe wildfire.



Citation: Coop, Jonathan D.; Holsinger, Lisa; McClernan, Sarah; Parks, Sean A. 2015. Influences of previous wildfires on change, resistance, and resilience to reburning in a montane southwestern landscape. Pages 273-276. In: Keane, Robert E.; Jolly, Matt; Parsons, Russell; Riley, Karin (editors). Proceedings of the large wildland fires conference; May 19-23, 2014; Missoula, MT. Proceedings RMRS-P-73. Fort Collins, CO: USDA Forest Service, Rocky Mountain Research Station.

Summary:

The authors used non-metric multidimensional scaling to assess how time-since-fire and burn severity of a previous fire affected the severity of patches on the Las Conchas fire, and how vegetation patterns changed following the fire.
