Small Area Estimation Of Postfire Tree Density In The Western United States Using An Annualized Forest Inventory, George Chilton Gaines Iii
Small Area Estimation Of Postfire Tree Density In The Western United States Using An Annualized Forest Inventory, George Chilton Gaines Iii
Graduate Student Theses, Dissertations, & Professional Papers
Wildfire activity in the western United States is expanding and concern for the declining extent of postfire tree cover in many western forests is mounting. Accurate estimates of postfire seedling, sapling, and large tree density following wildfire are critical for postfire forest management planning and monitoring forest dynamics. National forest inventory programs, such as the US Forest Service Forest Inventory and Analysis (FIA) program, can provide vegetation data for direct spatiotemporal domain estimation of postfire tree density, but sample observations within domains of administrative utility are often few to none. This research investigates indirect domain estimators, which borrow sample data …
Sula Study Revisited: 20-Year Post-Fire Regeneration In The Southern Bitterroot Valley, Montana., Luke Alan Rymniak
Sula Study Revisited: 20-Year Post-Fire Regeneration In The Southern Bitterroot Valley, Montana., Luke Alan Rymniak
Graduate Student Theses, Dissertations, & Professional Papers
In the summer of 2000, a number of large fires burned in the southern Bitterroot Valley near Sula, Montana. Research was conducted in 2001 and 2003 in the fire-affected areas of the French Basin and Larid Creek areas in order to investigate the effects of environmental variables, fire severity, and post-fire management on vegetation regeneration. In 2020 these areas were remeasured to understand trends over time by evaluating the impact of these same factors 20 years post fire. The results showed that the effects of environmental variables, fire severity, and post-fire management on vegetation regeneration were varied. The most influential …

Wildland fire is an important disturbance agent in the western US and globally. However, the natural role of fire has been disrupted in many regions due to the influence of human activities, which have the potential to either exclude or promote fire, resulting in a "fire deficit" or "fire surplus," respectively. In this study, we developed a model of expected area burned for the western US as a function of climate from 1984 to 2012. We then quantified departures from expected area burned to identify geographic regions with fire deficit or surplus. We developed our model of area burned as …
