Repeated fire altered succession and increased fire behavior in basin big sagebrush–native perennial grasslands
Year: 2020
The structure and composition of sagebrush-dominated ecosystems have been altered by changes in fire regimes, land use, invasive species, and climate change. This often decreases resilience to disturbance and degrades critical habitat for species of conservation concern. Basin big sagebrush (Artemisia tridentata ssp. tridentata) ecosystems, in particular, are greatly reduced in distribution as land has been converted to agriculture and other land uses. The fire regime, relative proportions of shrub and grassland patches, and the effects of repeated burns in this ecosystem are poorly understood…

The hot-dry-windy index: A new tool for forecasting fire weather
Year: 2020
Accurate predictions of how weather may affect a wildfire’s behavior are needed to protect crews on the line and efficiently allocate firefighting resources. Since 1988, fire meteorologists have used a tool called the Haines Index to predict days when the weather will exacerbate a wildfire. Although the Haines Index is widely believed to have value, it never received rigorous testing on the line. Even Don Haines, the U.S. Forest Service meteorologist who developed the index, has said the Haines Index needs further refinement. Recognizing that a new fire weather prediction tool was needed, a…

The 1994 Eastside screens large-tree harvest limit: review of science relevant to forest planning 25 years later
Year: 2020
In 1994, a large-tree harvest standard known as the “21-inch rule” was applied to land and resource management plans of national forests in eastern Oregon and Washington (hereafter, the “east side”) to halt the loss of large, old, live, and dead trees and old forest patches. These trees and forest patches have distinct ecological, economic, and social values, as reflected in widespread fish and wildlife use, public support for protecting them, and commercial interest in harvesting them, thus they have been the topic of much discussion and debate. At the request of regional Forest Service…

Joint Fire Science Program 2019 Progress Report
Year: 2020
Congress created the Joint Fire Science Program (JFSP) in 1998 as a partnership between the U.S. Department of Agriculture Forest Service and the Department of the Interior to identify and fund the research needs of the fire management community. Since that time, the JFSP has provided leadership to the fire community by identifying high-priority wildland fire science research needs that will enhance the decision making ability of fire and fuels managers, natural resource managers, and others to meet their management objectives. This progress report highlights a small sample of those research…

Insights and suggestions for certified prescribed burn manager programs
Year: 2020
Prescribed burning is an effective method to reduce hazardous fuels and restore ecological conditions across a variety of ecosystems. Twenty-one states have laws or policies that direct state agencies to oversee formal training programs to certify individuals in safe burning techniques. Fifteen of these states have active certified prescribed burn manager programs (CPBM). Michigan and Oregon did not implement certification programs due to lack of funding, and California, Minnesota, Washington, and West Virginia are currently developing CPBM programs. The Washington State Legislature charged…

Bridging the research-management gap: landscape science in practice on public lands in the western United States
Year: 2020
Landscape science relies on foundational concepts of landscape ecology and seeks to understand the physical, biological, and human components of ecosystems to support land management decision-making. Incorporating landscape science into land management decisions, however, remains challenging. Many lands in the western United States are federally owned and managed for multiple uses, including recreation, conservation, and energy development. We argue for stronger integration of landscape science into the management of these public lands. We open by outlining the relevance of landscape science…
