Comparisons of Gambel's quail survey methods conducted in 2016 within the Mohave Desert of California with results and summaries Comparisons of Gambel's quail survey methods conducted in 2016 within the Mohave Desert of California with results and summaries

Data includes results collected in the Mohave Desert during 2016 using three survey methods (acoustic recording units, camera traps, and call-count surveys) to detect gamebirds, primarily Gambel's quail (Callipepla gambelii) but also including records of mourning dove (Zenaida macroura), Eurasian collared-dove (Streptopelia decaocto), and chukar (Alectoris chukar). ARU data includes the...

Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015) Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015)

This habitat model was developed to delineate a sampling frame for regional monitoring of coastal California gnatcatchers (Polioptila californica californica) to determine: 1) percent area occupied (PAO) in high and very high suitability habitat across conserved lands and participating military lands in the U.S. range in southern California; 2) changes in PAO over time; and 3) extinction...

This data release contains the boundaries of assessment units for the assessment of undiscovered oil and gas resources in the Horn River Basin, Cordova Embayment and Liard Basin in Alberta Basin Province, Canada. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined...

Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park

We installed an eddy covariance station on July 10, 2018 at Bison Flat, an acid-sulfate, vapor-dominated area (0.04-km2) in Norris Geyser Basin, Yellowstone National Park, WY to monitor variations in hydrothermal gas and heat emissions. Since then, this station has measured CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half...

Site and Survey Data for Dixie Valley Toads in Churchill County, Nevada, 2019 Site and Survey Data for Dixie Valley Toads in Churchill County, Nevada, 2019

These data include site- and survey-specific information for occupancy surveys of Dixie Valley Toads (Anaxyrus williamsi) collected in the Dixie Valley, Churchill County, Nevada, in May 2019. The data include both multiple surveys of the same sites and time-to-detection information to quantify detection probabilities and account for imperfect detection in assessments of Dixie Valley Toad...

Site and Survey Data for Amphibian Surveys in Yosemite National Park, 2018 Site and Survey Data for Amphibian Surveys in Yosemite National Park, 2018

These data represent occupancy surveys conducted in long-term monitoring sites in Yosemite National Park in 2018 for three anurans, the Yosemite Toad (Anaxyrus canorus), the Sierran Treefrog (Pseudacris sierra), and the Sierra Nevada Yellow-legged Frog (Rana sierrae). The data include independent double-observer surveys and time-to-detection data to calculate detection probabilities and...
