The authors investigated the relative influence of top-down climate controls versus bottom-up vegetation controls on the timing and spatial pattern of fire in a historically fragmented and patchy ponderosa pine landscape.
The authors assessed fire-on-fire interactions in three wilderness areas to see how past fire area burned and fire severity affect subsequent fire.
The authors sampled post-fire surface fuels, woody debris and regeneration along a chronosequence of eighteen years within ponderosa pine stands that burned at high severity to understand how surface fuels change with time since fire.
The authors studied the effects of time since fire on the structural development of regeneration and complexity in pinyon-juniper woodlands along a long-term chronosequence of ~370 years.
The authors monitored prescribed fire in old-growth mixed conifer stands for eight consecutive years to examine the long-term effects on forest structure and how the actual results compared to restoration objectives.
The author resampled vegetation study plots originally sampled in Grand Canyon National Park in 1935 to document changes in forest structure and composition.
The authors examined the effects of recent prescribed and resource benefit fires on the fuel loads, structure, and potential fire behavior in ponderosa pine and pinyon-juniper woodlands. Additionally, they studied the effects of repeated resource benefit fire on those same ecosystems.
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 projected how large fire (> 200 ha) occurrence, size, and spatial location may be affected by climate change in the forests of the Greater Yellowstone area.
The authors reconstructed fire dates and stand-replacing fire patch sizes using four dendrological approaches to document the historical role of high severity and/or stand-replacing fire in upper elevation mixed-conifer, aspen, and spruce-fir forests.
