Metagenomic approaches to determine soil microbial communities associated with Armillaria root disease

Armillaria root disease causes extensive damage to tree roots throughout the world, but efficacious management practices are lacking. However, soil interactions among Armillaria species, microbial communities, and trees may determine the impact of pathogenic Armillaria on the growth and survival of trees. Two species, A. solidipes (highly virulent) and A. altimontana (less virulent), frequently co-occur in forests of inland northwestern USA.

Development of tools for early detection, monitoring and management of the koa wilt pathogen (Fusarium oxysporum f. sp. koae) in Hawaiíi

Koa (Acacia koa Gray) is an endemic, keystone species in Hawai’i’s forests. Koa is valuable economically (contributed $30 million to Hawai’i’s forestry industry in 2001), ecologically (habitat for many endangered birds and insects), and culturally (koa is the main wood used for making Hawaiian canoes). Mortality of koa trees due to koa wilt (caused by Fusarium oxysporum f. sp.

Proceedings-research and management of bitterbrush and cliffrose in Western North America

Bitterbrush and cliff rose are perhaps the most widely managed shrubs in Western North America. This proceedings of 27 papers is a collection of our current knowledge on research and management of bitterbrush, cliffrose, and other rosaceous shrubs in Western North America.

Engaging the fire before it starts: A case study from the 2017 Pinal Fire (Arizona)

How did the forest and community get to the point where they were willing to take on managing a fire of this size and duration for resource benefit and hazard reduction? Science has recognized for decades that many forested ecosystems of the American West are shifting away from historically fire-adapted conditions. Beginning in the 1970’s a small handful of managers recognized this issue and developed wildland fire use concepts.

The phylogeography of westslope cutthroat trout

Identifying units of conservation of aquatic species is fundamental to informed natural resources science and management. We used a combination of mitochondrial and nuclear molecular methods to identify potential units of conservation of Westslope Cutthroat Trout Oncorhynchus clarkii lewisi, a taxon native to montane river basins of the northwestern United States and southwestern Canada.

Risk perception, aensemaking and resilient performance: The sounds of wildland firefighting in action

Managing wildland fire is an exercise in risk perception, sensemaking and resilient performance. Risk perception begins with individual size up of a wildfire to determine a course of action, and then becomes collective as the fire management team builds and continuously updates their common perception of risk.

Assessing water contamination risk from vegetation fires: Challenges, opportunities and a framework for progress

Water crises - defined as significant declines in water quality and quantity - top the global risks list compiled by the World Economic Forum (2015) that have the greatest potential impacts on society. Vegetation fires are amongst the most hydrologically significant landscape disturbances (Ebel & Mirus, 2014) and affect ~4% of the global vegetated land surface annually (Giglio, Randerson, & van der Werf, 2013).

The first basic teaching guide for introducing High Reliability Organizing to the wildland fire community: From the field to line officers

This special guide for teaching and facilitating High Reliability Organizing (HRO) reflects the presentations that were made at the three-day May 2007 Facilitating HRO in Wildland Fire workshop. By using and following this guide, the HRO teacher will understand the fundamentals of HRO and will be better prepared to facilitate these principles to others.

The Rangeland Vegetation Simulator: A decision support tool for monitoring and projecting grassland conditions

Rangeland landscapes occupy roughly 662 million acres in the coterminous U.S. (Reeves and Mitchell 2011) and their vegetation responds quickly to climate and management, with high relative growth rates and inter-annual variability. Current national decision support systems in the U.S.

Examining dispatching practices for Interagency Hotshot Crews to reduce seasonal travel distance and manage fatigue

Interagency Hotshot Crews (IHCs) are a crucial firefighting suppression resource in the United States. These crews travel substantial distances each year and work long and arduous assignments that can cause accumulated fatigue. Current dispatching practices for these crews are supposed to send the closest resource while adhering to existing fatigue-management policies.
