View synthesis.
This synthesis (Chapter 4 in Invasive Plant Ecology and Management) approaches restoration with the understanding that precipitation, solar radiation, wind speed, air temperature, and humidity are principal drivers controlling energy and water flux in plant communities.

Results of this study identify attributes important for delineating habitats or modeling connectivity, which will facilitate conservation and management of landscapes important for supporting current and future sage-grouse populations.

In this review of recent literature and meta-analysis of seeding after wildfires, the authors found that seeding has little effect on erosion during the first year after fire and is highly dependent upon initial establishment and coverage of species in successive years. Older seedings were more likely to show reductions in invasives than younger seedings. Seedings with high plant establishment were more likely to reduce invasives than those with low establishment.

This guide provides a set of tools that will help field biologists, land managers, and private landowners conduct rapid qualitative field assessments that address the kind of site and its current state. These tools include a list of questions to be addressed and a series of photographs, keys, tables, and figures to help evaluate a site. Conducting this assessment will help prioritize sites to be treated, select the best treatment, and predict outcomes.

This purpose of this article is to outline how weather and climate information can be used to facilitate Ecologically-Based Invasive Plant Management (EBIPM) and adaptive management planning. The discussion follows the eight steps to adaptive management outlined in EBIPM planning guides.

This guide describes the benefits, opportunities, and trade-offs concerning fuel treatments in the dry mixed conifer forests of northern California and the Klamath Mountains, Pacific Northwest Interior, northern and central Rocky Mountains, and Utah. It provides (1) exhaustive summaries and links to supporting guides and literature on the mechanics of fuel treatments, including mechanical manipulation, prescribed fire, targeted grazing and chemical use; (2) a decision tree to help managers select the best mechanical method for any situation in these regions; (3) discussion on how to apply prescribed fire to achieve diverse and specific objectives; (4) key principles for developing an effective monitoring plan; (5) economic analysis of mechanical fuel treatments in each region; and (6) discussion on fuel treatment longevity.

This study evaluated restoration efforts applied to grasslands dominated by an invasive plant, sulfur cinquefoil, 6 yr after treatments. Of the five herbicides evaluated, picloram continued to provide the best control of sulfur cinquefoil over 6 yr. Plots with picloram applied in the fall had greater native forb cover. Seeding resulted in a 20% decrease in exotic grass cover. Successful establishment of native perennial grasses was not apparent until 6 yr after seeding. Our study found integrating herbicide application and the addition of native grass seed to be an effective grassland restoration strategy, at least in the case where livestock are excluded.

This Nature article discusses large, severe fires, climate change, insect outbreaks, and recovery of western forests with USGS scientist, Craig Allen and WERC scientist, Nate Stephenson. on the conversion of forest ecosystems due to climate change and altered fire regimes.
Climate change, forests, fire, water, and fish: building resilient landscapes, streams, and managers
View report.
This report describes the framework of how fire and climate change work together to affect forest and fish communities. Learning how to adapt will come from testing, probing, and pushing that framework and then proposing new ideas. The western U.S. defies generalizations, and much learning must necessarily be local in implication. This report serves as a scaffold for that learning. It comprises three primary chapters on physical processes, biological interactions, and management decisions, accompanied by a special section with separately authored papers addressing interactions of fish populations with wildfire.
