Fine-scale spatial climate variation and drought mediate the likelihood of reburning

Publications Posted on: March 27, 2018
In many forested ecosystems, it is increasingly recognized that the probability of burning is substantially reduced within the footprint of previously burned areas.

Modeling relationships among 217 fires using remote sensing of burn severity in southern pine forests

Publications Posted on: January 30, 2017
Pine flatwoods forests in the southeastern US have experienced severe wildfires over the past few decades, often attributed to fuel load build-up. These forest communities are fire dependent and require regular burning for ecosystem maintenance and health. Although prescribed fire has been used to reduce wildfire risk and maintain ecosystem integrity, managers are still working to reintroduce fire to long unburned areas.

Long-term, landscape patterns of past fire events in a montane ponderosa pine forest of central Colorado

Publications Posted on: December 27, 2016
Parameters of fire regimes, including fire frequency, spatial extent of burned areas, fire severity, and season of fire occurrence, influence vegetation patterns over multiple scales. In this study, centuries-long patterns of fire events in a montane ponderosa pine - Douglas-fir forest landscape surrounding Cheesman Lake in central Colorado were reconstructed from fire-scarred trees and inferences from forest stand ages.

Fire in Ghana's dry forest: Causes, frequency, effects and management interventions

Publications Posted on: September 29, 2015
This paper describes the number of fires, area burned, causes and seasonality of fires over a ten year period from 2002-2012 and investigates different fire management strategies and their effectiveness in the Afram headwaters forest reserve in Ghana. Data were collected from interviews of stakeholders in two communities adjacent to the reserve, and from 2002-2012 fire reports of the Ghana National Fire Service and Forest Service Division.

Understory vegetation response after 30 years of interval prescribed burning in two ponderosa pine sites in northern Arizona, USA

Publications Posted on: July 07, 2011
Southwestern USA ponderosa pine (Pinus ponderosa C. Lawson var. scopulorum Engelm.) forests evolved with frequent surface fires and have changed dramatically over the last century. Overstory tree density has sharply increased while abundance of understory vegetation has declined primarily due to the near cessation of fires.

Defining old growth for fire-adapted forests of the Western United States

Publications Posted on: December 17, 2007
There are varying definitions of old-growth forests because of differences in environment and differing fire influence across the Intermountain West.

Fire frequency effects on fuel loadings in pine-oak forests of the Madrean Province

Publications Posted on: October 25, 2007
Loadings of downed woody fuels in pine-oak forests of the Madrean Province are heavier on sites in southeastern Arizona with low fire frequencies and lower on sites in northeastern Sonora, Mexico, with high fire frequencies. Low fire frequencies in southeastern Arizona are attributed largely to past land uses and the fire suppression policies of land management agencies in the United States.

Frequent fire alters nitrogen transformations in ponderosa pine stands of the inland Northwest

Publications Posted on: July 19, 2007
Recurrent, low-severity fire in ponderosa pine (Pinus ponderosa)/interior Douglas-fir (Pseudotsuga menziesii var. glauca) forests is thought to have directly influenced nitrogen (N) cycling and availability.

Local-scale controls of a low-severity fire regime (1750-1950), southern British Columbia, Canada

Publications Posted on: July 05, 2007
Historical low-severity fire regimes are well characterized in ponderosa pine and mixed-conifer forests at many sites in the western United States, but not in the southern interior of British Columbia, Canada.

Relationships between fire frequency and woody canopy cover in a semi-arid African savanna

Publications Posted on: February 16, 2007
Landscape-scale fire patterns result from complex interactions among weather, ignition sources, vegetation type and the biophysical environment (Hargrove et al. 2000, Morgan et al. 2001, Keane et al. 2002, Hudak, Fairbanks & Brockett in press). Patch characteristics (e.g.
