Salinity yield modeling spatial data for the Upper Colorado River Basin, USA Salinity yield modeling spatial data for the Upper Colorado River Basin, USA
These data (vector and raster) were compiled for spatial modeling of salinity yield sources in the Upper Colorado River Basin (UCRB) and describe different scales of watersheds in the Upper Colorado River Basin (UCRB) for use in salinity yield modeling. Salinity yield refers to how much dissolved salts are picked up in surface waters that could be expected to be measured at the watershed...
Historical and 21st century soil temperature and moisture data for drylands of western U.S. and Canada Historical and 21st century soil temperature and moisture data for drylands of western U.S. and Canada
These data represent simulated soil temperature and moisture conditions for current climate, and for future climate represented by all available climate models at two time periods during the 21st century. These data were used to: 1) quantify the direction and magnitude of expected changes in several measures of soil temperature and soil moisture, including the key variables used to...
Colorado River Eddy Sandbar Dynamics Data Colorado River Eddy Sandbar Dynamics Data
These data are a compilation of the characteristics of eddy sandbars, eddy sandbar areas and volumes measured between 1990 and 2015, and longitudinal metrics of the Colorado River in Grand Canyon National Park, Arizona. These data were used to evaluate the response of sandbars to controlled floods implemented in 1996, 2004, 2008, 2012, 2013, and 2014. These data were also used to...
Northern Arizona Ponderosa Pine Forest Treatment Terrestrial Lidar Data Northern Arizona Ponderosa Pine Forest Treatment Terrestrial Lidar Data
These are terrestrial laser scanner datasets collected in forested areas west of Flagstaff, Arizona in 2015 and 2016. For each of the two scanners, six treatment areas were scanned, with four of them overlapping one another (Figure 1). These data are composed of individual scans referenced to one another using reflective targets, and geolocated using differentially corrected GPS and RTK...
Puma concolor GPS Telemetry and Path Identification Index (2003-2013), Southwest Region, USA Puma concolor GPS Telemetry and Path Identification Index (2003-2013), Southwest Region, USA
Capture, GPS-collar tagging, and release of cougars was conducted in northern Arizona and southern Utah and Nevada, USA, from 2003 to 2013 by the U.S. Geological Survey and the National Park Service (Northern Arizona University IACUC Protocol # 02-082-R4), resulting in GPS-tracking and monitoring of study animal activities. This data set includes six individuals that met three criteria...
Demographic modeling data (including code) at various sites in the Great Basin, USA Demographic modeling data (including code) at various sites in the Great Basin, USA
These data were compiled to determine whether transient population dynamics substantially alter population growth rates of sagebrush after disturbance, impede resilience and restoration, and in turn drive ecosystem transformation. Data were collected from 2014-2016 on sagebrush population height distributions at 531 sites across the Great Basin that had burned and were subsequently...
Long-term precipitation reduction experiment in the Colorado Plateau - Survival and mortality data from 2010 to 2018 Long-term precipitation reduction experiment in the Colorado Plateau - Survival and mortality data from 2010 to 2018
From 2011-2018 USGS biologists recorded vegetation and biological soil crust (BSC) cover by species and tracked survival of tagged individual plants (388 in total) across 40 locations where paired experimental plots had been installed in 2010. Plant cover was visually estimated using four 75 x 100 cm survey frames. Each site contained a two plots measuring 1.5 by 2.0 meteres: a control...
Riparian vegetation data used for comparing sampling methods along the Colorado River, Grand Canyon, Arizona Riparian vegetation data used for comparing sampling methods along the Colorado River, Grand Canyon, Arizona
These data were collected as part of a methodologial comparison for collecting riparian vegetation data. Two common methods for collecting vegetation data were used: line-point intercept and 1m2 ocular quadrats (visual cover estimates). At each site and transect, both methods were used to collect cover and composition data by four different observers. The same transects and quadrats were...
Erosion and Rehabilitation Data, Bandelier National Monument, New Mexico, USA Erosion and Rehabilitation Data, Bandelier National Monument, New Mexico, USA
These data were compiled for a restoration experiment testing the regenerative and functional response of biocrust inoculum reintroduced to a field setting. Regenerative traits measured included measurements of biocrust cover, chlorophyll content, and the roughness of the soil surface. Functional traits measured included nutrient cycling and soil stability. Additionally, these data were...
Laboratory Predation Data (various nonnative warm-water sport fishes), Arizona Laboratory Predation Data (various nonnative warm-water sport fishes), Arizona
These data were compiled to evaluate the potential impact various environmental conditions may have on native fish populaitons through predation. Introduced warm-water sport fishes present a high predation risk for juvenile native fishes, but observations of juvenile native fish surviving and recruiting in some rare cases led us to question what environmental conditions might be...
Russian-thistle field and seed bank data at Petrified Forest National Park, Arizona, 2015-2016 Russian-thistle field and seed bank data at Petrified Forest National Park, Arizona, 2015-2016
These data were compiled as part of a field and growth chamber study of the establishment of Salsola tragus (Russian thistle), an invasive non-native annual plant in North America. Field work was conducted at Petrified Forest National Park, Arizona in 2015 and 2016 and the growth chamber study was conducted in 2016. The data represent field measurements of Salsola germination and growth...
Predictive maps of 2D and 3D surface soil properties and associated uncertainty for the Upper Colorado River Basin, USA Predictive maps of 2D and 3D surface soil properties and associated uncertainty for the Upper Colorado River Basin, USA
The raster datasets in this data release are maps of soil surface properties that were used in analyzing different approaches for digital soil mapping. They include maps of soil pH, electrical conductivity, soil organic matter, and soil summed fine and very fine sand contents that were created using both 2D and 3D modeling strategies. For each property a map was created using both 2D and...
