Increasing weight of evidence that thinning and burning treatments help restore understory plant communities in ponderosa pine forests
Year: 2015
For more than a century ecosystems around the world have experienced an increase in the dominance of woody species. While the drivers of woody plant proliferation are complex, interactions between climate and land-use change are commonly invoked as primary contributing factors. In ponderosa pine forests of western North America, substantial increases in tree densities are impacting overall forest health and increasing the risk for severe wildfires and insect and disease outbreaks. Addressing this problem through the use of ecological restoration projects is widely advocated. Our objective was…

Before Wildfire Strikes: A Handbook for Homeowners and Communities in Southwest Oregon
Year: 2015
This is a manual that helps homeowners and neighborhoods prepare their areas and their homes for wildfire. A fire-adapted community is a community located in a fire-prone area that requires little assistance from firefighters during a wildfire. Residents of these communities accept responsibility for living in a high fire-hazard area. They possess the knowledge and skills to prepare their homes and property to survive wildfire; evacuate early, safely and effectively; and survive, if trapped by wildfire.

Drivers of Wildfire Suppression Costs: Literature Review and Annotated Bibliography
Year: 2015
Over the past century, wildland fire management has been core to the mission of federal land management agencies. In recent decades, however, federal spending on wildfire suppression has increased dramatically; suppression spending that on average accounted for less than 20 percent of the USFS’s discretionary funds prior to 2000 had grown to 43 percent of discretionary funds by 2008 (USDA 2009), and 51 percent in 2014 (USDA 2014). Rising suppression costs have created budgetary shortfalls and conflict as money “borrowed” from other budgets often cannot be paid back in full, and resources for…

Tracking Progress: The Monitoring Process Used in Collaborative Forest Landscape Restoration Projects in the Pacific Northwest
Year: 2015
Several trends have emerged in recent years that affect the management of the National Forest System, particularly in the western U.S. One is the recognition of landscapes departed from a natural range of variation, especially with implications for wildfire management. Another trend is the economic decline in many rural communities of the western U.S., particularly those based on natural resource activities such as timber production. Finally, there is increasing acceptance of collaborative approaches to forest management. Collaborative approaches endeavor to increase mutual learning among…

A state-and-transition simulation modeling approach for estimating the historical range of variability
Year: 2015
Reference ecological conditions offer important context for land managers as they assess the condition of their landscapes and provide benchmarks for desired future conditions. State-and-transition simulation models (STSMs) are commonly used to estimate reference conditions that can be used to evaluate current ecosystem conditions and to guide land management decisions and activities. The LANDFIRE program created more than 1,000 STSMs and used them to assess departure from a mean reference value for ecosystems in the United States. While the mean provides a useful benchmark, land managers and…

Historic Variability: Informing Restoration Strategies, Not Prescribing Targets
Year: 2014
The concept of historic range of variability (HRV) is briefly evaluatedwithin the context of its application in ecosystem managementover the past two decades. Despite caveats to the contrary, animplicit assumption continues to emerge of climatic stationarity,and, by corollary, that presettlement centuries provide an appropriatereference period. This is examined from the perspective ofhistoric climate change and ecosystem response. As a means ofdeveloping reference prescriptions and management targets, HRVis generally inappropriate, although if historic periods are usedfor reconstruction that…

Stewarding Forests and Communities: Final Report of the Dry Forest Zone Project
Year: 2014
During the past two decades, land managers and community leaders in the West have adopted sustainable land management methods to make forests healthier, and to maintain profitable local businesses that are beneficial to their communities. However their efforts were often siloed and were not making a big enough impact to offset the vast threat of wildfire and the effects of climate change that are increasingly pressing the region. Nor were these singular efforts being presented to federal lawmakers or agencies that have the need and ability to implement policies to replicate these successes…

Swiss Needle Cast
Year: 2013
Since the 1990s, there has been an epidemic of SNC affecting hundreds of thousands of acres of coastal Douglas-fir forests in Oregon, Washington and British Columbia. This constitutes one of the largest foliage-disease epidemics of conifers in North America. SNC is also a localized problem in many inland areas of the west, especially in Montana, Idaho, British Columbia, Washington, and Oregon.

A Land Manager's Guide for Creating Fire-resistant Forests
Year: 2013
This publication provides an overview of how various silvicultural treatments affectfuel and fire behavior, and how to create fire-resistant forests. In properlytreated, fire-resistant forests, fire intensity is reduced and overstory treesare more likely to survive than in untreated forests. Fire-resistant forestsare not “fireproof” – under the right conditions, any forest will burn. Much ofwhat we present here is pertinent to the drier forests of the Pacific Northwest,which have become extremely dense and fire prone

Communication of the Role of Natural Variability in Future North American Climate
Year: 2012
As climate models improve, decision-makers' expectations for accurate climate predictions are growing. Natural climate variability, however, poses inherent limits to climate predictability and the related goal of adaptation guidance in many places, as illustrated here for North America. Other locations with low natural variability show a more predictable future in which anthropogenic forcing can be more readily identified, even on small scales. We call for a more focused dialogue between scientists, policymakers and the public to improve communication and avoid raising expectations for…

Developing Socioeconomic Performance Measures for the Watershed Condition Framework
Year: 2012
The purpose of this report is to propose principles and strategies for creating socioeconomic performance measures, as well as identify potential measures that could be integrated into the WCF and other restoration frameworks in the short term. It also recommends a longer-term strategy to develop a social condition assessment and performance accountability system that could be paired with the WCF and terrestrial condition framework currently being developed. Finally, this report identifies potential barriers and challenges to adopting new performance measures, and potential approaches to…

Wildfire Suppression Contracting: The Effect of Local Business Capacity During Large Wildfires
Year: 2012
Contracting capacity and local capture can be the result of local economic conditions (supply side conditions) as well as agency contracting practices (demand side conditions). In order to capture contracts locally, local businesses that can perform the work need to exist, and past experience contracting with the federal government is a reasonable indicator of that capacity. To better understand local contracting capacity, we examined how local contract capture varied between wildfires and the relationship between local capture and contracting capacity measures. We investigated how the number…

Grazing After the Burn
Year: 2012
The rangelands and dry forests of Eastern Washington are considered “disturbance-driven” ecosystems. Disturbances are simply events that disturb normal ecosystem processes: nutrient and water cycling, plant growth and reproduction, animal interactions, etc. While all ecosystems experience some forms of disturbance, areas (like Eastern Washington) with extreme temperature variation, rough topography, scarcity of water, high soils variability, and high fire frequency experience more frequent and more severe disturbance than a Florida swamp forest, for an obvious example. Fire and grazing are…
