Substantial investments in fuel management activities on national forests in the western US are part of a
national strategy to reduce human and ecological losses from catastrophic wildfire and create fire
resilient landscapes. Prioritizing these investments within and among national forests remains a challenge,
partly because a comprehensive assessment that...

The history of fire between 1850 and 1977 in a portion of the
Willamette National Forest in-the central Western Cascades of Oregon was
documented using historical sources. Three types of records were
available: (1) records and writings not primarily concerned with fire
but yielding information about fire in context with...
Context:
Functional connectivity—the facilitation of individual movements among habitat patches—is essential for species’ persistence in fragmented landscapes. Evaluating functional connectivity is critical for predicting range shifts, developing conservation plans, and anticipating effects of disturbance, especially for species affected by climate change.
Objectives:
We examined whether simplifying forest structure influenced animal...

In many regions of the world, forest management has shifted from practices emphasizing timber production to more sustainable harvesting that integrates ecological values, including maintenance of biodiversity, wildlife habitat, and ecological goods and services. To this end, management strategies emphasize retention of stand structures that meet the needs of forest-obligate...

The Washougal Mining District is located on the western flanks of the southern Cascade Range of Washington, approximately 50 km (30 miles) northeast of Vancouver, Washington. The district has produced only $573 since 1903, derived from copper and silver. The presence of hydrothermal mineralization and breccia pipes similar to those...

Douglas-fir (Pseudotsuga menziesii) has a wide distribution in North America and is one of the
tree species most widely distributed outside its natural range. The species has been introduced to
Europe, New Zealand, South America, and elsewhere around the world. At present, Douglas-fir
is an accepted and integral part of...

Intensive cultivation of native grassland for dryland agriculture continuously depleted soil organic carbon (SOC) and nutrients. In 2010, we evaluated the influence of 80 yr of crop residue and nutrient management practices on SOC and N in 0- to 60-cm soil depth profiles in conventionally tilled winter wheat (Triticum aestivum...

Fishery management production models tend to stress only the elements directly linked to fish (i.e. fish, fish food, and fish predators). Large coastal jellyfish are major consumers of plankton in heavily fished ecosystems; yet, they are frequently not included as model components. We explore the relationship between gulf menhaden (Brevoortia...

The National Forest System (NFS) of the United States plays an important role in the carbon cycle because
these lands make up a large proportion of the forested land in the country and commonly store more wood
per unit area than other forest ownerships. In addition to sustaining natural resources,...
