Climate Change On The Shoshone National Forest, Wyoming: A Synthesis Of Past Climate, Climate Projections, And Ecosystem Implications, Janine Rice, Andrew Tredennick, Linda A. Joyce
United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications
The Shoshone National Forest (Shoshone) covers 2.4 million acres of mountainous topography in northwest Wyoming and is a vital ecosystem that provides clean water, wildlife habitat, timber, grazing, recreational opportunities, and aesthetic value. The Shoshone has experienced and adapted to changes in climate for many millennia, and is currently experiencing a warming trend that is expected to accelerate in the next century. Climate change directly and indirectly affects the Shoshone’s high-elevation, mountainous terrain that supports unique and sometimes rare ecological components. Several vulnerable and very responsive resources and processes on the Shoshone could interact to produce unforeseeable or undesirable ecosystem …

Phenology, by controlling the seasonal activity of vegetation on the land surface, plays a fundamental role in regulating photosynthesis and other ecosystem processes, as well as competitive interactions and feedbacks to the climate system. We conducted an analysis to evaluate the representation of phenology, and the associated seasonality of ecosystem- scale CO2 exchange, in 14 models participating in the North American Carbon Program Site Synthesis. Model predictions were evaluated using long-term measurements (emphasizing the period 2000–2006) from 10 forested sites within the AmeriFlux and Fluxnet-Canada networks. In deciduous forests, almost all models consistently predicted that the growing season started …

Fire And The Invasive Annual Grass Microstegium Vimineum In Eastern Deciduous Forests, S. Luke Flory, Keith Clay, Sarah Emery, Joseph Robb
Joint Fire Science Program Research Project Reports
Non-native plant invasions have the potential to change natural and prescribed fire regimes by increasing fuel loads, continuity of fuels, and fuel composition, which may alter fire intensity, damage native species, and promote further invasions. In this project we sought to evaluate the interaction between fire and the invasive annual grass Microstegium vimineum in eastern deciduous forests. Our goal was to determine if invasions enhance fire intensity, including fire temperatures, flame heights, and fire duration, and negatively affect tree regeneration, and stimulate further invasions. We also sought to determine how prescribed fires and the timing of fires affect the density …

Wildland Fire Suppression And Land Development In The Wildland/Urban Interface, Sheila Olmstead, Carolyn Kousky, Roger Sedjo
Joint Fire Science Program Research Project Reports
This project has explored the hypothesis that public fire suppression in fire‐prone areas acts as a subsidy to landowners, incentivizing conversion of land to residential and commercial development. Landowners do not bear the full cost of their choice to build on land in fire‐prone areas, since they do not pay for suppression, though they reap all of the benefits, potentially resulting in economically inefficient levels of development. To test this hypothesis, we performed an econometric analysis of U.S. land use change between 1970 and 2000. Statistically, we identified the impacts of changes in fire suppression policy by exploiting a natural …

To Burn Or Not To Burn Oriental Bittersweet: A Fire Manager’S Conundrum, Noel B. Pavlovic, Stacey A. Leicht-Young, Ralph Grundel, Scott A. Weyenberg, Neal Mulconrey
Joint Fire Science Program Research Project Reports
Oriental bittersweet (Celastrus orbiculatus) is an introduced liana (woody vine) that has invaded much of the Eastern United States and is expanding west into the Great Plains. In forests, it can girdle and damage canopy trees. At Indiana Dunes, we have discovered that it is invading non-forested dune habitats as well. Anecdotal evidence suggests that fire might facilitate its spread, but the relationship between fire and this aggressive invader is poorly understood. We investigated four areas important to fire management of oriental bittersweet, each of which we will briefly summarize here. 1) What fire temperatures cause seed mortality? For seeds, …

Using Escaped Prescribed Fire Reviews To Improve Organizational Learning, Anne E. Black Dr., James Saveland Dr., Dave Thomas, Jennifer Ziegler Dr.
Joint Fire Science Program Research Project Reports
The US wildland fire community has been interested in cultivating organizational learning to improve safety and overall performance for a number of years. A key focus has been on understanding the difference between culpability (to be guilty) and accountability (to explain) and on re-orienting review processes towards building a collective account of (as opposed to finding individual blame for) unwanted outcomes. A variety of innovative methodologies have been developed, yet until this project, there has been no systematic reflection to determine whether or how any of the existing review processes might be assisting organizational learning. Through a series of five …

Joint Fire Science Program Research Project Reports
Historically, wildfire was an important agent of change in landscapes across the western United States. Fires of varying magnitudes and extents contributed to a mosaic of dynamic landscape conditions. For the past century, fire management that focuses on fire suppression has effectively altered the composition of many vegetation communities across the landscape. Fire management and other landuse practices associated with natural resource use, agriculture, and residential development have changed the complexity of terrestrial landscapes. Aquatic systems have not been exempt from these changes: alterations in disturbance processes on the landscape have changed inputs into the stream environment, and practices such …

Affecting Risk: Improving Hazard Communication In The Wildland-Urban Interface, Melissa Wright Dr., Destiny Aman
Joint Fire Science Program Research Project Reports
Wildfire hazard is a growing problem in many areas of the United States, especially in the wildland-urban interface (WUI), where homes and other structures border or intermingle with forests, shrubs and grasslands. Despite years of educational outreach by fire management officials promoting effective and affordable mitigation strategies, research shows that residents, especially seasonal residents and those new to an area, still tend to under-invest in mitigation, even when they perceive their risk to be high. Meanwhile, the social and economic costs of wildfire have increased with fire size and intensity and far exceed the costs of mitigation. This problem has …

Age-Class Mosaics And Wind-Driven Fire: Further Fuel For The Debate, Jan L. Beyers, Philip J. Riggan, David Weise, Timothy Paysen, Marcia Narog
Joint Fire Science Program Research Project Reports
In 2006 the Santa Ana wind-driven Esperanza fire burned through the North Mountain Experimental Area (NMEA) and vicinity, including the scars of 10 previous fires. Multiple images of the fire’s progression were taken using PSW Research Station’s airborne FireMapper thermal-imaging system. Existing fuels data and historic NMEA maps plus new fire images were used to investigate relationships between vegetation history, fire behavior and severity, and fuel consumption. Soil samples were collected at a subset of fire severity sample points to assess seed bank survival. Coordinated documentation of vegetation recovery addressed the effects of age class and fire severity on chaparral …

Assessing Fuels Treatments In Southern California National Forests In The Context Of Climate Change, Timothy J. Brown, Crystal A. Kolden, John T. Abatzoglou
Joint Fire Science Program Research Project Reports
One of the key uncertainties in fuels treatments is their longevity under a changing climate. Several recent studies have assessed fuel treatment effectiveness during historic fires, and in many cases found the treatment less effective than desired, particularly during extreme or record conditions. In 2007, southern California experienced one of the most severe fire seasons to-date due to record low fuel moistures early in the fire season (a key driver of the two-month long Zaca fire) and historic Santa Ana winds late in the season (resulting in several large late October fires). Climate change projections for the region suggest that …

Can Climate Change Increase Fire Severity Independent Of Fire Intensity?, Phil Van Mantgem, Marybeth Keifer, Rob Klinger, Eric Knapp
Joint Fire Science Program Research Project Reports
We tested the idea that climate may affect forest fire severity independent of fire intensity. Pervasive warming can lead to chronic stress on forest trees (McDowell et al. 2008; Raffa et al. 2008), resulting in higher sensitivity to fire-induced damage (van Mantgem et al. 2003). Thus, there may be ongoing increases in fire severity (the number of trees killed), even when there is no change in fire intensity (the amount of heat released during a fire). We examined this question at a subcontinental scale by synthesizing existing information from plot-based prescribed fire monitoring databases across the western United States of …

Joint Fire Science Program Research Project Reports
Managers, regulators, and others often need information on the emissions from wildland fire and their expected smoke impacts. In order to create this information, combinations of models are utilized. The modeling steps follow a logical progression from fire activity through to emissions and dispersion. In general, several models and/or datasets are available for each modeling step, resulting in a large number of combinations that can be created to produce fire emissions or smoke impacts. Researchers, managers, and policy makers need information on how different model choices affect the resulting output, and guidance on what choices to make in selecting the …
