Locations of the eight sampled fires (red polygons) that burned with high severity in dry conifer forests of Arizona and New Mexico, USA (1996 to 2006). Inset shows drought conditions (Palmer Drought Severity Index, PDSI) in the study area from 1904 to 2013 and the year of the sampled fires (red dots). The fires all burned after 1996, when the region entered a period of significant prolonged drought (PDSI data from: https://doi.org/www.wrcc.dri.edu/wwdt/about.html, accessed January 2014).
