Citation: Flannigan, Michael D.; Cantin, Alan S.; de Groot, William J.; Wotton, B. Michael; Newbery, Alison; Gowman, Lynn M. 2013. Global wildland fire season severity in the 21st century. Forest Ecology and Management 294:54-61.


The authors modeled future global fire season severity due to climate change using the Cumulative Severity Rating, a weather-based fire danger metric, of the Canadian Forest Fire Danger Rating System.

Citation: Margolis, Ellis Q.; Swetnam, Thomas W. 2013. Historical fire-climate relationships of upper elevation fire regimes in the south-western United States. International Journal of Wildland Fire 22(5):588-598.


The authors reconstructed both regional climate teleconnections (ENSO, PDO, and AMO) and historical fire occurrence using tree-ring analysis. Their objectives were to analyze the relationship between moisture variability and regional, individual and phase combinations of, ENSO, PDO, and AMO and then compare this climate variability to fire occurrence in upper elevation forests across the southwest.

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.


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

Citation: Korb, Julie E.; Fulé, Peter Z.; Wu, Rosalind. 2013. Variability of warm/dry mixed conifer forests in southwestern Colorado, USA: Implications for ecological restoration. Forest Ecology and Management 304:182-191.


The authors compared the forest composition and structure along three transects at similar latitude and elevation in the San Juan National Forest to determine if climate synchronized fire occurrence across the large regional area historically.

Citation: Diaz, Henry F.; Swetnam, Thomas W. 2013: The wildfires of 1910: climatology of an extreme early twentieth-century event and comparison with more recent extremes. Bulletin of the American Meteorlogical Society 94(9):1361-1370.


The authors assessed the climate conditions preceding and during a period of intense fire activity across the western U.S. in the summer of 1910. They further evaluated other large regional fire years to determine if analogous climate conditions occurred during those periods of high fire activity.

Citation: Pausas, Juli G.; Ribeiro, Eloi. 2013. The global fire-productivity relationship. Global Ecology and Biogeography 22(6):728-736.


The authors tested the intermediate fire-productivity hypothesis across the world’s ecoregions that posit that fire is most common at the intermediate levels of aridity and productivity while either very arid or very productive ecosystems tend to decrease in flammability.

Citation: Fulé, Peter Z.; Yocom, Larissa L.; Cortés-Montaño, Citlali; Falk, Donald A.; Cerano, Julián; Villanueva-Díaz, José. 2012. Testing a pyroclimatic hypothesis on the Mexico-United States border. Ecology 93(8):1830-1840.


The authors reconstructed the fire regime of a relict unharvested stand in a remote Mexican mixed-conifer forest and compared it to a previously published fire regime data from a similar site in the Chiricahua Mountains of southeastern Arizona. The authors tested the pyroclimatic hypothesis to understand the relative influence of climate on ecologically and climatically similar sites, but with differing cultural influences.

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.


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.

Citation: Roos, Christopher I.; Swetnam, Thomas W. 2012. A 1416-year reconstruction of annual, multidecadal, and centennial variability in area burned for ponderosa pine forests of the southern Colorado Plateau region, Southwest USA. The Holocene 22(3):281-290.


The authors reconstructed the historical fire regime of the Colorado Plateau region over the previous 1,416 years to examine changes in the fire regime in response to climate variation, specifically periods of drought, and compare models of area burned and fire frequency in relation to climate before and after approximately 1600 CE.

Citation: Gartner, Meredith H.; Veblen, Thomas T.; Sherriff, Rosemary L.; Schoennagel, Tania L. 2012. Proximity to grasslands influences fire frequency and sensitivity to climate variability in ponderosa pine forests of the Colorado Front Range. International Journal of Wildland Fire 21(5):562-571.


The authors examined the relationship between fire frequency in ponderosa pine forests and their proximity to grassland and shrubland sites as well as the sensitivity to climate variation also related to the adjacency to these sites.
