Wind speed and relative humidity influence spatial patterns of burn severity in boreal forests of northeastern China

Publications Posted on: October 05, 2018
We investigated relationships between the spatial patterns of burn severity in Chinese boreal forests and weather parameters. Patch size, shape and arrangement differed between high-severity and low/moderate-severity patches.Wind speed and relative humidity were dominant weather parameters of spatial variation in burn severity.

Fire patterns in piñon and juniper in the Western United States: Trends from 1984 through 2013

Science Spotlights Posted on: May 15, 2018
Changes in fire patterns for piñon and juniper vegetation in the western United States were analyzed over a 30-year period. This is the first evaluation of its type.

Fire patterns in piñon and juniper land cover types in the Semiarid Western United States from 1984 through 2013

Publications Posted on: February 07, 2018
Increases in area burned and fire size have been reported across a wide range of forest and shrubland types in the Western United States in recent decades, but little is known about potential changes in fire regimes of piñon and juniper land cover types.

Bird habitat relationships along a Great Basin elevational gradient

Publications Posted on: May 12, 2016
Bird censuses were taken on 11 study plots along an elevational gradient ranging from 5,250 to 11,400 feet. Each plot represented a different vegetative type or zone: shadscale, shadscale-Wyoming big sagebrush, Wyoming big sagebrush, Wyoming big sagebrush-pinyon/juniper, pinyon/juniper, pinyon/juniper-mountain big sagebrush, mountain big sagebrush, mountain big sagebrush-mixed conifer, mixed conifer, mixed conifer-alpine, and alpine.

Publications Posted on: May 12, 2016
In the aftermath of the deaths of 14 firefighters during the South Canyon Fire in July 1994, fire scientists assessed what occurred and suggested guidelines that may help firefighters avert such a tragedy in the future.

Intercomparison of Fire Size, Fuel Loading, Fuel Consumption, and Smoke Emissions Estimates on the 2006 Tripod Fire, Washington, USA

Publications Posted on: September 09, 2015
Land managers rely on prescribed burning and naturally ignited wildfires for ecosystem management, and must balance trade-offs of air quality, carbon storage, and ecosystem health. A current challenge for land managers when using fire for ecosystem management is managing smoke production.

Predicting behavior and size of crown fires in the Northern Rocky Mountains

Publications Posted on: March 21, 2007
Describes methods for approximating behavior and size of a wind-driven crown fire in mountainous terrain. Covers estimation of average rate of spread, energy release from tree crowns and surface fuel, fireline intensity, flame length, and unit area power of the fire and ambient wind.
