A regional synthesis of climate data to inform the 2025 State Wildlife Action Plans in the Northeast U.S. A regional synthesis of climate data to inform the 2025 State Wildlife Action Plans in the Northeast U.S.
The State Wildlife Action Plans (SWAPs) are proactive planning documents, known as “comprehensive wildlife conservation strategies,” that assess the health of each state’s wildlife and habitats, identify current management and conservation challenges, and outline needed actions to conserve natural resources over the long term. SWAPs are revised every 10 years, with the last revision in...

Management of tidal wetland restoration and fish in the upper San Francisco Estuary: Where are we now and how do we move forward? A summary of the 2023 Wetland Science Symposium Management of tidal wetland restoration and fish in the upper San Francisco Estuary: Where are we now and how do we move forward? A summary of the 2023 Wetland Science Symposium
Tidal wetland restoration to benefit at-risk fish species in the Sacramento-San Joaquin Delta and Suisun marsh has gained momentum over the past decade, much of it in response to mitigation requirements for the State Water Project and Central Valley Project. In fall 2023, the Department of Water Resources and the State Water Contractors convened a symposium, entitled Delta-Suisun Tidal...

Amphibian and reptile conservation in the United States of America Amphibian and reptile conservation in the United States of America
Wildlife stewardship is of utmost importance in the United States, where management for sustainable natural resources is extended to native species including amphibians and reptiles. The U.S. wildlife conservation framework is a nested system of authorities regulating species and habitats, science-based management and policy decisions, and adaptive management as new knowledge is applied...

Colorado Delta riparian plant health improvement Colorado Delta riparian plant health improvement
The riparian corridor along Mexico’s arid Colorado River Delta is being affected by reduction in river flow and increases in heat, drought, human infrastructure, and disturbances. These disturbances can change riparian land cover by limiting water availability for riparian plant species, increasing fire intensity and frequency, and increasing soil and water salinities. In response to...

A journey to the center of the USGS National Strong-motion Project processing and beyond A journey to the center of the USGS National Strong-motion Project processing and beyond
The United States Geological Survey (USGS) National Strong Motion Project (NSMP) has the primary U.S. government responsibility to acquire, process, and disseminate significant strong-motion earthquake ground motion records measured at surficial free-field stations, structures (buildings, dams, and bridges, and geotechnical arrays to the earthquake engineering community. As a result of...

Salmon data mobilization Salmon data mobilization
Despite substantial research and conservation efforts, many salmon populations are in decline. Globally, salmon research is not delivering effective decision support products to help managers apply research insights as informed management actions. Data Mobilization (DM) is a key step towards building the wider evidence base required to deliver accountable, reliable, and usable scientific...

Models no not provide proof: An example of model ambiguity and application of isotopic data in a mine pit lake Models no not provide proof: An example of model ambiguity and application of isotopic data in a mine pit lake
Geochemical and hydrologic models of pit lakes are commonly used in environmental regulatory decisions to predict future water quality and hydrologic conditions and to understand existing pit lakes. Models may be used to quantify sulfide oxidation, predict thermal/chemical stratification and mixing, and better understand connections between pit lakes and aquifers. One concern related to...

New approaches to wildlife health New approaches to wildlife health
Recent environmental change and biodiversity loss have modified ecosystems, altering disease dynamics. For wildlife health, this trend has translated into increased potential for disease transmission and reduced capacity to overcome significant population-level impacts, which may place species at risk of extinction. Thus, current approaches to wildlife health focus not on the absence of...

A metapopulation strategy to support long term conservation of genetic diversity in Department of the Interior bison A metapopulation strategy to support long term conservation of genetic diversity in Department of the Interior bison
Once numbering in the tens of millions, plains bison (Bison bison bison) were nearly driven to extinction with only a few hundred individuals remaining by the late 19th century. Plains bison have since recovered to approximately 20,000 animals managed in conservation herds throughout North America, yet substantial challenges to their recovery remain. The Department of the Interior (DOI)...

Climate vulnerability assessment of Oregon hatchery programs Climate vulnerability assessment of Oregon hatchery programs
The goal of this project was to assess the vulnerability to climate change impacts for a sample set of hatchery programs representing different geographic areas and primary anadromous species raised in state-managed Oregon hatcheries (Summary Figure 1). Freshwater and marine ecosystem processes can significantly influence salmon and steelhead survival, and understanding how these factors...

Site-specific, extended ShakeMaps for earthquake engineering applications Site-specific, extended ShakeMaps for earthquake engineering applications
The U.S. Geological Survey (USGS) routinely produces ShakeMaps of shaking intensity across the globe. Due to practical constraints, the number of response spectral periods was limited to three standard periods (0.3, 1.0, and 3.0 sec). We have recently developed the tools that are necessary to expand this functionality to include 22 periods (matching the current U.S. National Seismic...
