Evaluating a seed technology for sagebrush restoration across an elevation gradient: Support for bet hedging

Publications Posted on: October 02, 2019
Big sagebrush (Artemisia tridentata Nutt.) restoration is needed across vast areas, especially after large wildfires, to restore important ecosystem services. Sagebrush restoration success is inconsistent, with a high rate of seeding failures, particularly at lower elevations. Seed enhancement technologies may overcome limitations to restoration success.

The role of short-term weather conditions in temporal dynamics of fire regime features in mainland Spain

Publications Posted on: October 02, 2019
In this paper we investigate spatial-temporal associations of fire weather danger and fire regime features from 1979 to 2013.

The missing fire: Quantifying human exclusion of wildfire in Pacific Northwest forests, USA

Publications Posted on: October 02, 2019
Western U.S. wildfire area burned has increased dramatically over the last half-century. How contemporary extent and severity of wildfires compare to the pre-settlement patterns to which ecosystems are adapted is debated. We compared large wildfires in Pacific Northwest forests from 1984 to 2015 to modeled historic fire regimes.

A social-ecological network approach for understanding wildfire risk governance

Publications Posted on: October 02, 2019
Large wildfire events (e.g.>100 square km) highlight the importance of governance systems that address wildfire risk at landscape scales and among multiple land owners and institutions. A growing body of empirical work demonstrates that environmental governance outcomes depend upon how well patterns of interaction among actors align with patterns of ecological connectivity, such as wildfire transmission.

The wildfire problem in areas contaminated by the Chernobyl disaster

Publications Posted on: October 02, 2019
This paper examines the issue of radionuclide resuspension from wildland fires in areas contaminated by the Chernobyl Nuclear Power Plant explosion in 1986. This work originated from a scientific exchange among scientists from the USDA Forest Service, Ukraine and Belarus that was organized to assess science and technology gaps related to wildfire risk management.

Incorporating social diversity into wildfire management: Proposing 'pathways' for fire adaptation

Publications Posted on: September 26, 2019
Existing research suggests that adoption or development of various wildfire management strategies may differ across communities.

Evaluating the factors responsible for post-fire water quality response in forests of the western USA

Publications Posted on: September 26, 2019
Wildfires commonly increase nutrient, carbon, sediment and metal inputs to streams, yet the factors responsible for the type, magnitude and duration of water quality effects are poorly understood. Prior work by the current authors found increased nitrogen, phosphorus and cation exports were common the first 5 post-fire years from a synthesis of 159 wildfires across the western United States.

Cesium emissions from laboratory fires

Publications Posted on: September 16, 2019
If a radiological incident such as a nuclear power plant accident, a radiological dispersal device, or detonation of an improvised nuclear device occurs, significant areas may be contaminated. Initial cleanup priorities would likely focus on populated areas, leaving the forested areas to pass several seasons where the overhead canopy materials would fall to the forest floor.

Wildfires alter forest watersheds and threaten drinking water quality

Publications Posted on: September 13, 2019
Wildfires are a natural part of most forest ecosystems, but due to changing climatic and environmental conditions, they have become larger, more severe, and potentially more damaging. Forested watersheds vulnerable to wildfire serve as drinking water supplies for many urban and rural communities.

Where the desert meets the river: Investigating southwestern riparian ecosystems

Science Spotlights Posted on: August 23, 2019
Rivers and streams of the American Southwest have been heavily altered by human activity, resulting in significant changes to disturbance regimes. Riparian vegetation in aridland floodplain systems is critically important as foraging, migrating, and breeding habitat to birds and other animal species. To conserve riparian ecosystems and organisms, understanding how plants and animals are affected by disturbance processes and multiple stressors is critical.
