Spatiotemporal patterns of unburned areas within fire perimeters in the northwestern United States from 1984 to 2014

Publications Posted on: May 11, 2018
A warming climate, fire exclusion, and land cover changes are altering the conditions that produced historical fire regimes and facilitating increased recent wildfire activity in the northwestern United States. Understanding the impacts of changing fire regimes on forest recruitment and succession, species distributions, carbon cycling, and ecosystem services is critical, but challenging across broad spatial scales.

Fire atlas for the Selway-Bitterroot Wilderness

Datasets Posted on: August 27, 2015
This fire atlas includes all 1972-2012 wildland fires at least 20 hectares (ha) or 50 acres in size that occurred within or intersected the Selway-Bitterroot Wilderness (Montana and Idaho). There are two main components of this fire atlas; the first being a fire history shapefile depicting fire perimeters, and the second being raster files representing satellite-inferred burn severity for these fires.

Fire atlas for the Gila and Aldo Leopold Wilderness areas

Datasets Posted on: August 27, 2015
This fire atlas includes all 1972-2012 wildland fires at least 20 hectares (ha) or 50 acres in size that occurred within or intersected the Gila and Aldo Leopold Wilderness areas in New Mexico. There are two main components of this fire atlas; the first being a fire history shapefile depicting fire perimeters, and the second being raster files representing satellite-inferred burn severity for these fires.

Fire atlas for the Frank Church-River of No Return Wilderness

Datasets Posted on: August 27, 2015
This fire atlas includes all 1972-2012 wildland fires at least 20 hectares (ha) or 50 acres in size that occurred within or intersected the Frank Church - River of No Return Wilderness in Idaho. There are two main components of this fire atlas; the first being a fire history shapefile depicting fire perimeters, and the second being raster files representing satellite-inferred burn severity for these fires.

Fire atlas for the Crown of the Continent Ecosystem (Glacier National Park, Great Bear Wilderness, Bob Marshall Wilderness, and Scapegoat Wilderness)

Datasets Posted on: August 27, 2015
This fire atlas includes all 1972-2012 wildland fires at least 20 hectares (ha) or 50 acres in size that occurred within or intersected the Crown of the Continent Ecosystem in Montana, which is comprised of Glacier National Park, Great Bear Wilderness, Bob Marshall Wilderness, and Scapegoat Wilderness.

Northern Rockies pyrogeography: An example of fire atlas utility

Publications Posted on: October 07, 2014
We demonstrated the utility of digital fire atlases by analyzing forest fire extent across cold, dry, and mesic forests, within and outside federally designated wilderness areas during three different fire management periods: 1900 to 1934, 1935 to 1973, and 1974 to 2008. We updated an existing atlas with a 12 070 086 ha recording area in Idaho and Montana, USA, west of the Continental Divide, 81 % of which is forested.

Multi-season climate synchronized forest fires throughout the 20th century, Northern Rockies, USA

Publications Posted on: September 02, 2008
We inferred climate drivers of 20th-century years with regionally synchronous forest fires in the U.S. northern Rockies. We derived annual fire extent from an existing fire atlas that includes 5038 fire polygons recorded from 12 070 086 ha, or 71% of the forested land in Idaho and Montana west of the Continental Divide.

Remote sensing techniques to assess active fire characteristics and post-fire effects

Publications Posted on: October 03, 2006
Space and airborne sensors have been used to map area burned, assess characteristics of active fires, and characterize post-fire ecological effects. Confusion about fire intensity, fire severity, burn severity, and related terms can result in the potential misuse of the inferred information by land managers and remote sensing practitioners who require unambiguous remote sensing products for fire management.
