Evaluation of runoff prediction from WEPP-based erosion models for harvested and burned forest watersheds

Publications Posted on: June 21, 2006
This study evaluates runoff predictions generated by GeoWEPP (Geo-spatial interface to the Water Erosion Prediction Project) and a modified version of WEPP v98.4 for forest soils. Three small (2 to 9 ha) watersheds in the mountains of the interior Northwest were monitored for several years following timber harvest and prescribed fires.

The way to a healthy future for National Forest ecosystems in the West : what role can silviculture and prescribed fire play?

Publications Posted on: June 20, 2006
The 1994 wildfires in the U.S. West have highlighted a problem of forest health and fuel buildups that has been increasing for decades. In many Western forest ecosystems, forest biomass per acre has risen substantially since the 1940s and many forests have dense, fire-prone understories.

The Science of Prescribed Fire: to Enable a Different Kind of Control

Publications Posted on: June 13, 2006
A paradigm shift from fire suppression to fire suppression and prescription requires a shift in emphasis from simply controlling wildfire occurrence and spread to one that includes controlling characteristics of prescribed fire. Suppression focuses on preventing unwanted effects that might result from wildfire occurrence. Prescription promotes desired effects by precisely and properly implementing fire occurrence.

Watershed improvement using prescribed burns as a way to restore aquatic habitat for native fish

Publications Posted on: June 12, 2006
The Nature Conservancy and Bureau of Land Management are testing a model that prescribed burns can be used to increase perennial grass cover, reduce shrubs in desert grassland, and improve watershed condition and aquatic habitat. Results of a prescribed burn in the Hot Springs Creek watershed on Muleshoe Ranch CMA demonstrated the predicted vegetation changes and watershed improvement.

An assessment of the spatial extent and condition of grasslands in the Apache Highlands ecoregion

Publications Posted on: June 12, 2006
Grasslands in the Apache Highlands ecoregion have experienced dramatic changes. To assess and identify remaining native grasslands for conservation planning and management, we used a combination of expert consultation and field verification. Over two-thirds of native grasslands have experienced shrub encroachment. More than 30% of these may be restorable with prescribed fire.

Response of two semiarid grasslands to a second fire application

Publications Posted on: April 12, 2006
Prescribed fire was used in two semiarid grasslands to reduce shrub cover, promote grass production, and reduce erosional loss that represents a potential nonpoint-source of sediment to degrade water quality.

Forest health through silviculture: proceedings of the 1995 National Silviculture Workshop, Mescalero, New Mexico, May 8-11, 1995

Publications Posted on: March 11, 2006
Includes 32 papers documenting presentations at the 1995 Forest Service National Silviculture Workshop. The workshop's purpose was to review, discuss, and share silvicultural research information and management experience critical to forest health on National Forest System lands and other Federal and private forest lands.

The challenge of restoring natural fire to wilderness

Publications Posted on: February 27, 2006
Despite clear legislative and policy direction to preserve natural conditions in wilderness, the maintenance of fire as a natural process has proven to be a significant challenge to federal land managers.

Prescribed fire as the minimum tool for wilderness forest and fire regime restoration: a case study from the Sierra Nevada, California

Publications Posted on: February 27, 2006
Changes in forest structure were monitored in areas treated with prescribed fire in Sequoia and Kings Canyon National Parks. Five years after the initial prescribed fires, tree density was reduced by 61% in the giant sequoia-mixed conifer forest, with the greatest reduction in the smaller trees.

Development of ecological restoration experiments in fire adapted forests at Grand Canyon National Park

Publications Posted on: February 27, 2006
The management of national park and wilderness areas dominated by forest ecosystems adapted to frequent, low-intensity fires, continues to be a tremendous challenge. Throughout the inland West and particularly in the Southwest, ponderosa pine (Pinus ponderosa) and mixed conifer forests have become dense and structurally homogeneous after periods of intense livestock grazing, followed by more than 100 years of fire suppression.
