The Rangeland Vegetation Simulator: A decision support tool for monitoring and projecting grassland conditions

Publications Posted on: December 06, 2018
Rangeland landscapes occupy roughly 662 million acres in the coterminous U.S. (Reeves and Mitchell 2011) and their vegetation responds quickly to climate and management, with high relative growth rates and inter-annual variability. Current national decision support systems in the U.S.

Effects and interactions of fire, logging, and grazing

Publications Posted on: August 01, 2018
In this chapter, we summarize current knowledge about the effects of fire, logging, and grazing on coniferous forest birds and their habitats. We critically review the results of studies evaluating how these individual factors influence bird numbers, species diversity, nesting success, and habitat use in ponderosa pine forests.

Fluvial processes in Puget Sound rivers and the Pacific Northwest [Chapter 3]

Publications Posted on: August 01, 2018
The variability of topography, geology, climate; vegetation, and land use in the Pacific Northwest creates considerable spatial and temporal variability of fluvial processes and reach-scale channel type. Here we identify process domains of typical Pacific Northwest watersheds and examine local physiographic and geologic controls on channel processes and response potential in the Puget Sound region.

Delineating climate refugia for native aquatic species with big crowd-sourced databases

Publications Posted on: April 12, 2018
Topographic diversity is the essence of mountain environments in western North America, a diversity that manifests itself hydrologically in a host of forms - rivers, streams, lakes, wetlands, and springs - that constitute habitats for a wealth of fish, amphibians, mussels, and insects.

Climate change and special habitats in the Blue Mountains: Riparian areas, wetlands, and groundwater-dependent ecosystems [Chapter 7]

Publications Posted on: April 14, 2017
In the Blue Mountains, climate change is likely to have significant, long-term implications for freshwater resources, including riparian areas, wetlands (box 7.1), and groundwater-dependent ecosystems (GDEs, box 7.2). Climate change is expected to cause a transition from snow to rain, resulting in diminished snowpack and shifts in streamflow to earlier in the season (Leibowitz et al. 2014, Luce et al. 2012; see chapter 3).

Evaluating reclamation success: the ecological consideration-proceedings of a symposium; 1990 April 23-26; Charleston, WV.

Publications Posted on: May 12, 2016
Includes 10 papers from a symposium organized to review what is know about the ecological principles that will govern the ultimate success or failure of all reclamation efforts on drastically disturbed lands. The papers cover four general areas: soil biological properties and nutrient cycling; vegetation dynamics; animal recolinization; and landscape-scale processes.

Modeling relationships between landscape-level attributes and snorkel counts of chinook salmon and steelhead parr in Idaho

Publications Posted on: May 12, 2016
Knowledge of environmental factors impacting anadromous salmonids in their freshwater habitats, particularly at large spatial scales, may be important for restoring them to previously recorded levels in the northwestern United States.

Landscape dynamics and considerations

Publications Posted on: May 12, 2016
Many studies in Southwestern ponderosa pine forests have investigated the relationships between songbirds and habitat characteristics at the level of individual patches (Hall et al. and Finch et al., this volume). To date, though, no published studies from Southwestern ponderosa pine forests have examined the relationships between songbirds and spatial patterns at the level of entire landscapes.

Seasonal habitat requirements for sage-grouse: spring, summer, fall, and winter

Publications Posted on: May 12, 2016
Sage-grouse (Centrocercus minimus, C. urophasianus) are dependent upon live sagebrush (Artemisia spp.) for all life processes across their entire range. This paper describes habitats used by sage-grouse as documented in the scientific literature. The leaves of sagebrush are eaten by sage-grouse throughout the entire year and comprise 99 percent of their winter diets.

Aquatic species and habitats

Publications Posted on: May 12, 2016
Continuing human activities threaten the highly prized aquatic resources of the interior Columbia basin. Precipitous declines in native species, particularly Pacific salmon, and a large influx of introduced species have radically altered the composition and distribution of native fishes. Fortunately, areas of relatively high aquatic integrity remain, much of it on federally administered lands.
