The importance of wilderness to whitebark pine research and management

Publications Posted on: March 07, 2006
Whitebark pine is a keystone species in upper subalpine forests of the northern Rocky Mountains, Cascades, and Sierra Nevada that has been declining because of recent mountain pine beetle and exotic blister rust epidemics, coupled with advancing succession resulting from fire exclusion.

Studies in the wilderness areas of the Kenai National Wildlife Refuge: fire, bark beetles, human development, and climate change

Publications Posted on: March 07, 2006
Wilderness areas comprise 65% of the 1.92 million acre Kenai National Wildlife Refuge, Alaska. Fire history studies indicate that fire frequency increased substantially in both white and black spruce forests after European settlement. Dendrochronolgy studies indicate that regional-scale spruce bark beetle outbreaks occurred in the 1820s, 1880s, and 1970s.

The federal wildland policy: opportunities for wilderness fire management

Publications Posted on: February 27, 2006
The Federal Wildland Fire Management Policy and Program Review represents the latest stage in the evolution of wildland fire management. This policy directs changes that consolidate past fire management practices into a single direction to achieve multidimensional objectives and creates increased opportunities for wilderness fire management.

Twentieth-century fire patterns in the Selway-Bitterroot Wilderness Area, Idaho/Montana, and the Gila/Aldo Leopold Wilderness Complex, New Mexico

Publications Posted on: February 27, 2006
Twentieth century fire patterns were analyzed for two large, disparate wilderness areas in the Rocky Mountains. Spatial and temporal patterns of fires were represented as GIS-based digital fire atlases compiled from archival Forest Service data. We find that spatial and temporal fire patterns are related to landscape features and changes in land use.

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.

Fire-climate interactions in the Selway-Bitterroot Wilderness area

Publications Posted on: February 27, 2006
Tree-ring reconstructed summer drought was examined in relation to the occurrence of 15 fires in the Selway-Bitterroot Wilderness Area (SBW). The ten largest fire years between 1880 and 1995 were selected from historical fire atlas data; five additional fire years were selected from a fire history completed in a subalpine forest within the SBW. Results of the analysis indicate summers during the fire year were significantly (p0.05).

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.

Restoring natural fire regimes to the Sierra Nevada in an era of global change

Publications Posted on: February 27, 2006
A conceptual model of fire and forest restoration and maintenance is presented. The process must begin with clearly articulated goals and depends upon derivation of science-driven models that describe the natural or desired conditions. Evaluating the extent to which contemporary landscapes depart from the model is a prerequisite to determining the need for restoration.

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.

Continuing fire regimes in remote forests of Grand Canyon National Park

Publications Posted on: February 27, 2006
Ponderosa pine forests in which frequent fire regimes continue up to the present would be invaluable points of reference for assessing natural ecological attributes.
