Evaluating Postfire Seeding Treatments Designed To Suppress Cheatgrass (Bromus Tectorum) In A Ponderosa Pine Forest On The Colorado Plateau, Matthew L. Brooks, Robert Klinger, Jennifer Chase, Curt Deuser
JFSP Research Project Reports
The restoration of historical fuel conditions and fire regimes is one of the primary land management goals in the Shivwits Plateau region of northwestern Arizona. Fire is the primary tool used in this region to reduce fuel loads and shift landscapes back to historical conditions of a low intensity, 8- 15 year return interval, surface fire regime. However, the invasive plant cheatgrass has become the dominant understory vegetation and fuel type following initial fire treatments in many areas. There is significant concern that repeated burning at historically appropriate fire return intervals for ponderosa pine forest will benefit this invasive plant …

Post-Fire Treatment Effectiveness For Hillslope Stabilization, Peter R. Robichaud, Louise E. Ashmun, Bruce D. Sims
JFSP Synthesis Reports
This synthesis of post-fire treatment effectiveness reviews the past decade of research, monitoring, and product development related to post-fire hillslope emergency stabilization treatments, including erosion barriers, mulching, chemical soil treatments, and combinations of these treatments. In the past ten years, erosion barrier treatments (contour-felled logs and straw wattles) have declined in use and are now rarely applied as a post-fire hillslope treatment. In contrast, dry mulch treatments (agricultural straw, wood strands, wood shreds, etc.) have quickly gained acceptance as effective, though somewhat expensive, post-fire hillslope stabilization treatments and are frequently recommended when values-at-risk warrant protection. This change has been motivated …

Bending, Like The Reed In The Wind: A System To Restore Northwestern Forests, Lisa-Natalie Anjozian
JFSP Briefs
Silviculture is the study, cultivation, and management of forest trees. It is rooted in science, but often is an art based on the experience of the forester. This story explores free-selection, a silvicultural system developed by scientists that allows managers and stakeholders greater fl exibility in growing new forests. By using this system for applying treatments, managers craft a vision of the desired short- and long-term conditions of the forest. The focus is placed on how the remaining forest components will function, rather than focusing on stand structure guidelines that dictate stand treatments and tree removal.

Nature In A Name: Paulownia Tomentosa—Exotic Tree, Native Problem, Lisa-Natalie Anjozian
JFSP Briefs
While awareness of fire’s importance in dry Appalachian forests, and the application of fire as a restoration tool have increased over the last two decades, so too has the post-fire invasion of Paulownia tomentosa (Princess tree). For the last ten years, managers have witnessed Paulownia invasion grow following fi re events. To understand this better, the team studied five life history transitions for the species: seed dispersal, seed germination, seed survival over time through incorporation in the seed bank, initial habitat requirements, and seedling persistence to maturity. Paulownia seeds were found to disperse over two miles from their source tree. …

The Northeast Washington Forestry Coalition: A Citizen-Agency Partnership That Works, Bruce Shindler
JFSP Briefs
With the urgency of wildfi re near every community’s door, federal agencies have sought a middle ground between the extremes of timber-industry and environmental positions, one that would enable active management to reduce fuels and create safer communities. At the same time, citizen groups have organized themselves to protect important community values connected with their neighboring forests. These developments have set the stage for increasingly successful multi-stakeholder partnerships. The collaborative processes facilitated by these partnerships require considerable patience and perseverance at the outset, but the result can be a healthier forest, reduced fi re risk, more stable planning processes, and …

Filling In Knowledge Gaps In North Carolina, Elise Lequire
JFSP Briefs
North Carolina is divided into three broad physiographic regions, from the low-lying Atlantic Coastal Plain, to the midelevation foothills—the Piedmont Plateau—to the higher elevation Blue Ridge and Appalachian zone. Understanding the behavior of fire in these widely different regions, as in much of the southeastern United States, presents challenges that differ sharply from those common in the West, where the emphasis on fire science research has been greater. An ambitious project has helped fill in local and regional knowledge gaps, as researchers gathered data and assessed the relevance and limitations of existing tools, including remote satellite sensing, weather station information, …

Sink Or Source? Fire And The Forest Carbon Cycle, Christina Frame
JFSP Briefs
As the size and severity of fires in the western U.S. continue to increase, it has become ever more important to understand carbon dynamics in response to fire. Many subalpine forests experience stand-replacing wildfires, and these fires and subsequent recovery can change the amount of carbon released to the atmosphere because subalpine forests store large amounts of carbon. Stand-replacing fires initially convert ecosystems into a net source of carbon as the forest decomposes—a short-term effect (decades) that will likely be important over the next century if fire frequency increases as a result of climate change. Over the long term (centuries), …

The Good Earth: Run-Off, Erosion, And Recovery In The Post-Fi Re Chaparral Steeplands Of Southern California, Lisa-Natalie Anjozian
JFSP Briefs
In September 2002, the Williams Fire burned 38,184 acres of chaparral steeplands, including more than 90 percent of the San Dimas Experimental Forest. The 1960 Johnstone Fire had burned many of the same watersheds some forty years earlier, thus providing opportunities to compare post-fire watershed response coupled with management efforts that had converted some native chaparral areas to grassland. With scant studies on soil water repellency, plant recovery, and their effects on watershed hydrology, managers face diffi culties in planning for erosion/run-off problems. The researchers delivered quantifi ed data on changing soil properties, the character and structure of regenerating plants, …

Frequencies, Lasers, And Wavelengths: A Quest For Affordable, Landscape Scale Remote Sensing, Marjie Brown
JFSP Briefs
New developments in high-resolution remote sensing systems have demonstrated the potential for generating direct, more accurate, and efficient estimates of fuels and the vegetation characteristics that influence fire behavior at the landscape scale. Two of these direct measurement tools are operated from aircraft and known by their acronyms LIDAR (Light Detection and Ranging) and IFSAR (Interferometric Synthetic Aperture Radar). IFSAR is less costly than LIDAR, and unlike LIDAR, IFSAR sees through clouds and smoke. This project sought to evaluate the utility of IFSAR data for characterizing vegetation structure in the chaparral-dominated landscapes typical over much of southern California. The researchers …

Exploring Patterns Of Burn Severity In The Biscuit Fire In Southwestern Oregon, Joy Drohan
JFSP Briefs
Large wildfires are important ecologically and economically, but their behavior and effects are not well understood, especially in the Klamath-Siskiyou region, which is characterized by a diversity of conifers and evergreen sprouting hardwoods, steep topography, variable geology, and strong climatic gradients. These studies used new analytical tools to characterize conditions before and after a large wildfire and to analyze those data across the entire landscape of the fire. Some of the general findings may apply to other forest regions, but the details may be unique to southwestern Oregon and northwestern California. The results improve our understanding of how post-fire management …

After A Southern Pine Beetle Epidemic, Jake Delwiche
JFSP Briefs
Southern pine beetles are a serious insect threat to pine forests in the South, from eastern Texas to Virginia. Beetles attack most pine species by boring through the bark of the tree and constructing long, winding tunnels between the bark and the wood, eventually girdling and killing the tree. They also introduce a fungus called “bluestain,” which further damages conductive systems of the tree. After an outbreak, the area of dead standing timber is usually no longer of commercial value. Forest managers are interested in reducing these fuel hot spots, both to allow forest regeneration and to reduce wildfire risk. …

In this article, we analyze whether the Softwood Lumber Agreement between the United States and Canada imposed significant economic costs on industries that use softwood lumber in the United States. To ascertain this impact, we use an event study. Our event study analyzes variations in the stock prices of lumber-using firms listed at the major stock markets in the United States. We find that the news of events leading to the Softwood Lumber Agreement had significant negative impacts on the stock prices of industries using softwood lumber. The average reduction of stock prices for our sample of firms was approximately …
