Mixed-Severity Wildfire as a Driver of Vegetation Change in an Arizona Madrean Sky Island System, USA

Abstract: Fire is a powerful natural disturbance influencing vegetation patterns across landscapes. Recent transitions from mixed-species forests to post-fire shrublands after severe wildfire is an increasingly prevalent phenomenon in pine-oak and conifer forest ecosystems in southwestern North America. However, we know little about how variation in fire severity influences other common forest types in the region. In this study, we evaluated fire-induced changes in woody plant community composition and forest structure … Show more

“…Although very little work has been done on fire regimes in P. X fallax, Juniperus deppeana, and J. monosperma woodlands, we can draw parallels from other Pinus edulis or P. discolor areas regarding crown fires that are the natural fire cycle, albeit with shorter cycles (~200 years), and a difference likely attributed to the chaparral fuel conditions [38]. Many recent fires in these types appear to be within the historic range of variability [39].…”

“…The increasing frequency and intensity of megafires cause stand-replacing burns resulting in dramatic community assemblage changes, including conversions from conifers to hardwoods and forests to shrub-dominated communities (Barton and Poulos 2018, Hagmann et al 2021, O'Connor et al 2021, Poulos et al 2021. Recent severe fires in four Arizona sky islands have impacted more than half of their total area (Villarreal et al 2019), while models project that Madrean sky islands will lose significant areas of montane habitat in the next few decades due to climate change (Yanahan and Moore 2019).…”

“…Lafontaine 1982;Davenport 2018;Albu & Albu 2023). These regions and habitats have been suffering from increased drought due to climate change, recent forest fire intensity and perhaps also frequency (Westerling et al 2006;O'Connor et al 2014;Poulos et al 2021). Even though most of the associated literature is focused on plants, especially on wooden plants (e.g.…”

“…Even though most of the associated literature is focused on plants, especially on wooden plants (e.g. Kaib et al 1996;Morino et al 2000;Monroy-Gamboy et al 2021;Poulos et al 2021), it is plausible to assume that the phenomenon also affects insects, along with the changes in vegetation, even if this is hardly documented (see Forister et al 2010). In part, the recent intensive forest fires have been due to historical fire suppression and hence accumulation of increased amounts of fuel.…”
