Wildfire contribution to desertification at local, regional, and global scales [Chapter 8]

Publications Posted on: July 08, 2019
Wildfire is a natural phenomenon that began with the development of terrestrial vegetation in a lightning-filled atmosphere of the Carboniferous Period (307-359 million years before the present). Sediment deposits from that era contain evidence of charcoal from post-fire ash slurry flows. As human populations developed in the Pleistocene and Holocene epochs, mankind transformed fire into one of its oldest tools.

Characterizing persistent unburned islands within the Inland Northwest USA

Publications Posted on: July 01, 2019
Background: In the Inland Pacific Northwest of the United States, fire is a dominant driver of ecological change. Within wildfire perimeters, fire effects often vary considerably and typically include remnant patches of unburned islands. As fires reburn the landscape, some unburned islands remain persistently unburned.

An assessment of fire refugia importance criteria ranked by land managers

Publications Posted on: May 30, 2019
There is evidence that forest resiliency is declining in the western US due to recent increases in both areas burned by wildfire and the number of large fires. Fire refugia may increase forest resiliency; however, for land managers to incorporate fire refugia into their management plans, methods need to be developed to identify and rank criteria for what make fire refugia important.

Integrating subjective and objective dimensions of resilience in fire-prone landscapes

Publications Posted on: May 22, 2019
Resilience has become a common goal for science-based natural resource management, particularly in the context of changing climate and disturbance regimes. Integrating varying perspectives and definitions of resilience is a complex and often unrecognized challenge to applying resilience concepts to social-ecological systems (SESs) management.

Reforestation Matters

Science Spotlights Posted on: May 01, 2019
The number of global initiatives for forest restoration, and the scope of these initiatives, continues to increase. An important tool for meeting objectives of these global initiatives is reforestation, achieved by natural processes or by tree planting. Worldwide, organizations are challenged to most efficiently and effectively direct resources to the most critical reforestation needs. Currently in the United States, the reforestation efforts of the USDA Forest Service, are challenged by changes in policy, funding, climate change, and mega-fires, to name a few, and identifying strategies for timely successful reforestation at scale is needed.

Science framework for conservation and restoration of the sagebrush biome: Linking the Department of the Interior’s Integrated Rangeland Fire Management Strategy to long-term strategic conservation actions. Part 2. Management applications

Publications Posted on: April 12, 2019
The Science Framework is intended to link the Department of the Interior’s Integrated Rangeland Fire Management Strategy with long-term strategic conservation and restoration actions in the sagebrush biome. The focus is on sagebrush (Artemisia spp.) ecosystems and sagebrush dependent species with an emphasis on Greater sage-grouse (Centrocercus urophasianus).

Tradeoffs between US national forest harvest targets and fuel management to reduce wildfire transmission to the wildland urban interface

Publications Posted on: April 09, 2019
US public land management agencies are faced with multiple, often conflicting objectives to meet management targets and produce a wide range of ecosystem services expected from public lands. One example is managing the growing wildfire risk to human and ecological values while meeting programmatic harvest targets for economic outputs mandated in agency budgets.

Mortality and flowering of Great Basin perennial forbs after experimental burning: Implications for wild bees

Publications Posted on: April 09, 2019
The fates of native bee communities in the Great Basin sagebrush steppe are linked with the susceptibilities of their floral hosts to increasingly frequent wildfires. Postfire survival and subsequent flowering of six prevalent perennial wildflowers representing five families were quantified across a range of realistic fire severities created using a calibrated propane burn barrel.

A national approach to leverage the benefits of tree planting on public lands

Publications Posted on: March 27, 2019
The number of global initiatives for forest restoration, and the scope of these initiatives, continues to increase. An important tool for meeting objectives of these global initiatives is reforestation, achieved by natural processes or by tree planting.
