The authors looked at the effects of climate change on invasive species establishment in western deserts. Specifically, they examined the effects of the interannual variation of temperature- and precipitation-related indicators associated with the National Fire Danger Rating System (NFDRS). Furthermore, they projected the future influence of large fire potential into the mid-21st century using downscaled CGM models.
The authors examined how patterns of fire severity at multiple spatial scales affect long-term (30 to 50 years) ponderosa pine regeneration and survivalunder current altered fire regimes. They also considered how subsequent entries of fire influenced seedling survival, as well as biotic and abiotic factors (e.g., topographical and elevational gradients) that affect survival, germination, and growth of ponderosa pine.
The authors evaluate the implementation and effectiveness of a thinning and burning forest restoration treatment to meet forest structure objectives in a ponderosa pine forest.
The authors used the Random Forest algorithm in R to analyze the comparative strength of a suite of topographic variables and Potential Vegetation Type (PVT) to predict high severity fire occurrence from 1984 to 2004 in the Gila Wilderness.
The authors analyzed the effects of the severity of a fire on the severity of a subsequent reburn based on the vegetation type. The analysis was stratified by vegetation types that burned frequently historically, including piñyon-juniper woodlands, ponderosa pine dominated forests, mixed-conifer, and spruce-fir.
This article was a review of literature regarding tree mortality due to water stress and increased temperatures as a result of climate change in forests around the world.
The authors created a process for evaluating the ecological sustainability of fire-adapted ecosystems in the face of climate change and analyzed a case study in ponderosa pine forests on the Kaibab Plateau within the Kaibab National Forest.
The authors assessed the widespread tree mortality that has occurred in coniferous forests in the western U.S. and Canada and identified possible causes of the increased mortality.
This paper is a systematic review of vegetation recovery in warm deserts post-fire. The authors evaluated post-fire species composition based on time-since-fire and each desert, post-fire sprouting frequency, and perennial plant cover establishment.
