Compounding Climate Effects on Amphibians

In montane ecosystems of the U.S. Pacific Northwest, increasing temperatures are resulting in a transition from snow-dominated to rain-dominated precipitation events, reducing snowpack.

A Spatially Continuous Model of Annual Streamflow Permanence Throughout the Pacific Northwest

An interdisciplinary team comprised of USGS and university scientists has developed the Probability of Streamflow Permanence Model or PROSPER which predicts flow permanence for unregulated and minimally impaired streams in the Pacific Northwest.

Guide to Bees of Southern Idaho

Bees are an important part of natural ecosystems and thriving agricultural systems in southwest Idaho and other areas of the United States. Both introduced and native bees can provide ecosystem services by pollinating native plants and agricultural crops such as fruit trees.

Estimating Extinction Risk for Multiple Populations When Data for Traditional Population Viability Analyses are Unavailable

Population viability analysis (PVA) bridges the gap between theoretical and applied ecology and is used to make policy decisions on high-profile conservation efforts. However, it’s use is limited to a single or few populations with long-term data.

The State of Olympic National Park – The Natural Resource Condition Assessment

The USGS and National Park Service (NPS) have published the first Natural Resource Condition Assessment for Olympic National Park. A Natural Resource Condition Assessment, or NRCA, is a report that evaluates a subset of important natural resources in a NPS Unit.

Identification of Secretive Marsh Birds with Statistical Analyses of Recorded Calls

The king and clapper rail are rare and cryptic marsh birds. When encountered, one would likely hear their kek call. But which species is it?

Post-fire Sagebrush Recovery Looks to Landsat Time Series Data for Solutions

When a wildfire rampages through a sagebrush domain, restoring the landscape’s natural vegetation afterward is often a dicey proposition. But now complicate that situation with soil-moisture-robbing drought either before or after the fire. What becomes the best restoration solution then?

Multi-Partner Workshop Highlights Science Actions for a Potential Wildlife Disease Outbreak

A new USGS Open-File Report outlines findings from a scenario building workshop on a wildlife disease, facilitated by the Department of the Interior’s Strategic Sciences Group (SSG) and led by the USGS.

Multispecies Analysis of Climate Sensitivity in the Pacific Northwest

Species rarity and life history traits are known within the field of conservation biology to be associated with extinction risk and may also be employed to inform their sensitivity or capacity to adapt to future climates.

Effects of Disturbance on Vascular Plants and Biocrusts in Sagebrush Steppe

Semi-arid sagebrush ecosystems experience chronic disturbances through grazing, invasive grasses, and acute disturbance of fire. Biocrusts, a community of cyanobacteria, mosses, and lichens, develop on soil surfaces and contribute to the land’s resistance to invasive plants.

Vegetative Community Response to Landscape Scale Post-fire Herbicide (Imazapic) Application

The timing of herbicide application following wildfire can strongly influence its effectiveness. USGS researchers evaluated the effect of the commonly used herbicide imazapic on targeted exotic annual grasses and non-target plants, applied the first winter or second fall after the 2015 Soda wildfire.

Protocol for Describing Indicators of Rangeland Health

Assessing rangeland health is useful from a land management perspective in providing a baseline or early indicator of degradation and for prioritizing habitat across a landscape for restoration.
