Characterizing ecoregions and montane perennial watersheds of the Great Basin

Publications Posted on: November 18, 2020
Multiple research and management partners collaboratively developed a multiscale approach for assessing the geomorphic sensitivity of streams and ecological resilience of riparian and meadow ecosystems in upland watersheds of the Great Basin to disturbances and management actions. The approach builds on long-term work by the partners on the responses of these systems to disturbances and management actions.

Modeling wildland firefighter travel rates by terrain slope: Results from GPS-tracking of Type 1 crew movement

Publications Posted on: September 29, 2020
Escape routes keep firefighters safe by providing e_ffcient evacuation pathways from the fire line to safety zones. Effectively utilizing escape routes requires a precise understanding of how much time it will take firefighters to traverse them. To improve this understanding, we collected GPS-tracked travel rate data from US Interagency Hotshot “Type 1” Crews during training in 2019.

Spatial variation in the response of tiger gene flow to landscape features and limiting factors

Publications Posted on: June 17, 2020
Integrated landscape management of key population areas along with the corridors linking them is important for tiger conservation in the Indian subcontinent. Relationships between gene flow and landscape patterns, however, cannot be generalized given that different limiting factors influence movement in different spatial contexts.

The ecology, history, ecohydrology, and management of pinyon and juniper woodlands in the Great Basin and Northern Colorado Plateau of the western United States

Publications Posted on: January 30, 2020
This synthesis reviews current knowledge of pinyon and juniper ecosystems, in both persistent and newly expanded woodlands, for managers, researchers, and the interested public. We draw from a large volume of research papers to centralize information on these semiarid woodlands. The first section includes a general description of both the Great Basin and northern Colorado Plateau.

Characterizing persistent unburned islands within the Inland Northwest USA

Publications Posted on: July 01, 2019
Background: In the Inland Pacific Northwest of the United States, fire is a dominant driver of ecological change. Within wildfire perimeters, fire effects often vary considerably and typically include remnant patches of unburned islands. As fires reburn the landscape, some unburned islands remain persistently unburned.

Topographic and fire weather controls of contemporary fire refugia in forested ecosystems of northwestern North America

Publications Posted on: July 10, 2018
Fire refugia, sometimes referred to as fire islands, shadows, skips, residuals, or fire remnants, are an important element of the burn mosaic, but we lack a quantitative framework that links observations of fire refugia from different environmental contexts. Here, we develop and test a conceptual model for how predictability of fire refugia varies according to topographic complexity and fire weather conditions.

Next Generation Fire Severity Mapping

Tools Posted on: July 06, 2018
The Next Generation Fire Severity Mapping is a tool designed to depict the probability of high-severity fire, if a fire were to occur, for several ecoregions in the contiguous western U.S. Statistical models were used to generate “wall-to-wall” maps for 13 of the 19 ecoregions. 

Principles and practices for the restoration of ponderosa pine and dry mixed-conifer forests of the Colorado Front Range

Publications Posted on: January 26, 2018
Wildfires have become larger and more severe over the past several decades on Colorado’s Front Range, catalyzing greater investments in forest management intended to mitigate wildfire risks. The complex ecological, social, and political context of the Front Range, however, makes forest management challenging, especially where multiple management goals including forest restoration exist.

The spatially varying influence of humans on fire probability in North America

Publications Posted on: August 10, 2016
Humans affect fire regimes by providing ignition sources in some cases, suppressing wildfires in others, and altering natural vegetation in ways that may either promote or limit fire.

Digital surface, terrain, and canopy height models for the Bannock Creek unit of Boise Basin Experimental Forest in 2007

Datasets Posted on: August 27, 2015
The data publication contains 1 meter raster data sets for three different digital elevation models (DEM) for the Bannock Creek unit of the Boise Basin Experimental Forest in south central Idaho in November 2007. The first is a digital terrain model (DTM), which is the ground surface with all vegetation and human-made structures removed. The second is a digital surface model (DSM), which includes all vegetation and human-made structures.
