Citation: Parks, Sean A.; Dobrowski, Solomon Z.; Panunto, Matthew H. 2018. What drives low-severity fire in the southwestern USA? Forests 9(4):165.

Summary:

The authors evaluated both climate and biophysical factors that influence the occurrence of low severity fire in the Southwest. Low severity fire is an important component of many high frequency, fire-adapted ecosystems in the southwest, so understanding those conditions which promote low severity fire is highly relevant to land managers.



Citation: Loehman, Rachel; Flatley, Will; Holsinger, Lisa; Thode, Andrea. 2018. Can land management buffer impacts of climate changes and altered fire regimes on ecosystems of the Southwestern United States? Forests 9(4):192.

Summary:

Using two mechanistic ecosystem-fire models, Fire BGCv2 in the Jemez Mountains and LANDIS-II in the Kaibab, the authors projected contemporary climate and two future emissions scenarios (“warm-dry” and “hot-arid”) to the year 2100 to predict changes to forests and fire regimes in a ponderosa pine and a mixed-conifer ecosystem. They also modeled four management strategies (suppression-only, current treatment intensity, and three and six times current treatment intensity) to see if management may be able to counteract the effects of climate change on forest composition and structure.



Citation: Margolis, Ellis Q.; Malevich, Steven B. 2016. Historical dominance of low-severity fire in dry and wet mixed-conifer forest habitats of the endangered terrestrial Jemez mountains salamander (Plethodon neomexicanus). Forest Ecology and Management 375:12-26.

Summary:

The authors reconstructed the historical stand structure and fire regimes along a gradient of ponderosa pine to wet mixed-conifer and aspen stands within the habitat of the endangered Jemez Mountains salamander. They further related the variability of climate to the historic fire regime.



Citation: Coppoletta, Michelle; Merriam, Kyle E.; Collins, Brandon M. 2016. Post-fire vegetation and fuel development influences fire severity patterns in reburns. Ecological Applications 26(3):686-699.

Summary:

The authors sampled field plots that reburned to examine how biophysical characteristics, topography, fire weather, time-since-fire, and initial fire severity affected subsequent reburn severity



Citation: Abatzoglou, John T.; Williams, A. Park. 2016. Impact of anthropogenic climate change on wildfire across. western US forests. Proceedings of the National Academy of Sciences of the United States of America 113(42):11770-11775.

Summary:

The authors quantified the contribution of past anthropogenic climate change to increases in area burned based on observed increases in fuel aridity metrics from 1979 to 2015, including temperature and vapor pressure deficit.



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: 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: 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.
