Back to the Future: Building resilience in Colorado Front Range forests using research findings and a new guide for restoration of ponderosa and dry-mixed conifer landscapes

Publications Posted on: February 01, 2018
Historically, the ponderosa and dry mixed-conifer forests of the Colorado Front Range were more open and grassy, and trees of all size classes were found in a grouped arrangement with sizable openings between the clumps. As a legacy of fire suppression, today’s forests are denser, with smaller trees. Proactive restoration of this forest type will help to reduce fuel loads and the risk of large and severe wildfires in the Colorado Front Range.

Should I stay or should I go now? Or should I wait and see? Influences on wildfire evacuation decisions

Publications Posted on: January 10, 2018
As climate change has contributed to longer fire seasons and populations living in fire-prone ecosystems increase, wildfires have begun to affect a growing number of people. As a result, interest in understanding the wildfire evacuation decision process has increased.

Stream water quality concerns linger long after the smoke clears: Learning from Front Range wildfires

Publications Posted on: December 14, 2017
Large, high-severity wildfires alter the ecological processes that determine how watersheds retain and release nutrients and affect stream water quality. These changes usually abate a few years after a fire but recent studies indicate they may persist longer than previously expected.

Fire evolution in the radioactive forests of Ukraine and Belarus: future risks for the population and the environment

Publications Posted on: October 07, 2016
In this paper, we analyze the current and future status of forests in Ukraine and Belarus that were contaminated after the nuclear disaster in 1986. Using several models, together with remote-sensing data and observations, we studied how climate change in these forests may affect fire regimes.

Factors related to building loss due to wildfires in the conterminous United States

Publications Posted on: September 30, 2016
Wildfire is globally an important ecological disturbance affecting biochemical cycles and vegetation composition, but also puts people and their homes at risk. Suppressing wildfires has detrimental ecological effects and can promote larger and more intense wildfires when fuels accumulate, which increases the threat to buildings in the wildland- urban interface (WUI).

Pretreatment variation in overstory and understory vegetation [Chapter 2]

Publications Posted on: August 20, 2016
Changes in forest vegetation as a result of fire exclusion, sheep and cattle grazing, and large-tree logging have been well documented for western forests (Agee 1998; Arno et al. 1997; Covington and Moore 1994; Everett et al. 2000; Harrod et al. 1999; Hessburg and Agee 2003; Hessburg et al. 2000, 2005). These changes in forest structure and composition have increased the hazard of large, highseverity wildfires (Agee 1994, Peterson et al.

Reburns and their Impact on carbon pools, site productivity, and recovery [Chapter 13]

Publications Posted on: June 23, 2016
Prior to fire suppression and exclusion, wildfires and other disturbances (e.g., insects, disease, and weather) sustained ecosystem processes in many landscapes of the Western United States. However, wildfires have been increasing in size, frequency, and intensity in recent years (Kellogg and others 2008).

Managing the unexpected in prescribed fire and fire use operations: a workshop on the High Reliability Organization

Publications Posted on: May 12, 2016
Fire management, and forest and rangeland fuels management, over the past century have altered the wildland fire situation dramatically, thus also altering the institutional approach to how to deal with the changing landscape. Also, climate change, extended drought, increased insect and disease outbreaks, and invasions of exotic plant species have added complications to fire management on public and private lands.

Is forest structure related to fire severity? Yes, no, and maybe: Methods and insights in quantifying the answer

Publications Posted on: May 12, 2016
Wildfires in 2000 burned over 500,000 forested ha in the Northern Rocky Mountains. In 2001, National Fire Plan funding became available to evaluate the influence of pre-wildfire forest structure on post wildfire fire severity. Results from this study will provide information on forest structures that are resilient to wildfire. Three years of data (558 plots) have been collected from forested areas that burned in 2000, 2001, and 2002.
