Investigation of land cover within wetland complexes at Dixie Meadows, Churchill County, Nevada, from October 2015 to January 2022

The U.S. Geological Survey investigated land cover at subannual time steps within six wetland areas in Dixie Valley, Churchill County, Nevada, from October 2015 to January 2022. As requested by the U.S. Fish and Wildlife Service, we used aerial photography and satellite remote sensing data to map surface water and other land cover types within the wetland complexes. We identified five land cover c

Ecological trade-offs associated with fuel breaks in the sagebrush ecosystem

BackgroundUnprecedented wildfire frequency, fueled by invasive annual grasses, threatens sagebrush ecosystems. To suppress wildfire and conserve sagebrush, land management agencies have installed fuel breaks across the sagebrush biome. However, despite the potential reduction in wildfire, fuel breaks may have ecological costs. Determining an acceptable balance between risks and benefits of fuel br

Practical application of time-lapse camera imagery to develop water-level data for three hydrologic monitoring sites in Wisconsin during water year 2020

Using camera imagery to measure water level (camera-stage) is a well-researched area of study. Previous camera-stage studies have shown promising results when implementing this technology with tight constraints on test conditions. However, there is a need for a more comprehensive evaluation of the extensibility of camera-stage to practical applications. Therefore, the aim of this study was to test

Blue Catfish | Invasive Species We Study

Blue Catfish ( Ictalurus furcatus ) is native to the lower and middle Mississippi River and its tributaries and to the Rio Grande River. Many states outside of the native range stocked Blue Catfish to provide angling opportunities and to meet other fishery management objectives as early as the early 1900s. In the Chesapeake Bay watershed and in some eastern seaboard states, Blue Catfish is an...

Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 35 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 35 states and four provinces and in captive cervid facilities in 22 states and three provinces.

Impacts of changing climate and disturbance regimes on forest ecosystem resilience in the Southern Rocky Mountains

Climate-driven forest disturbances, particularly drought-induced tree mortality and large high-severity fires from increasingly warm and dry conditions, are altering forest ecosystems and the ecosystem services society depends on (e.g., water supplies) in the Southern Rockies and across the Western U.S. We will combine unique, long-term place-based ecological data, diverse methods (e.g., paleo...
