Vegetation and Soils Data from Grazed and Ungrazed Watersheds in the Badger Wash Study Area, Colorado, USA

In 2004 U.S. Geological Survey biologists recorded vegetation and biological soil crust (BSC) cover by species as well as measured soil stability and compaction data along 85 transects at the Badger Wash study area, approximately 10 miles northwest of Mack in western Colorado. Soil samples were collected and processed for chemistry and texture. Using analysis of variance and nonmetric multi...

Hatchery Trout Predation Data, Arizona

These data were compiled to evaluate the potential adverse impacts that stocked trout may have on native fish populaitons through predation. Hatchery-reared rainbow and brown trout are typically fed exclusively on commercially prepared pelleted feeds and have no experience catching or consuming life fish at the time of stocking and yet stocked fish are percieved to present a high predation...

The influence of water temperature on salmonid recruitment and adult size in tailwaters across western North America—Data

These data were used to examine drivers behind changes in water temperature downriver of dams across the western U.S. from 1995-2015 and the influence of such changes on rainbow trout recruitment and rainbow and brown trout adult length. First, we linked reservoir storage capacity and dam size to the warmest monthly water temperature per water year (WY) to assess the influence of low storage...

Spatial distribution and risk analysis data for diamond-backed terrapins relative to crab trapping, Savannah Coastal Refuge Complex, USA

There were five objects for compiling these data: 1) to conduct a systematic inventory of diamond-backed terrapins (Malaclemys terrapin) using headcount surveys on four National Wildlife Refuges (Harris Neck, Blackbeard Island, Wassaw, and Wolf Island) that are a part of the greater Savannah Coastal Refuges Complex in southeast Georgia, USA; 2) to use occupancy modeling to

Geomorphic Change-Sediment Transport Data for the Little Colorado River, Arizona, USA

These data were compiled to accompany flow modeling work on Little Colorado river above the mouth (USGS gage 09402300). The data include topographic data collected by LIDAR and total station in June 2017, high water marks from nine historic floods, and control points and gage structures. Topographic data include ground topography collected by LIDAR and channel bathymetry collected by to

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Special Features Points

The Central Mojave Special Features shapefile provides point locations for known or potential places where vegetation alliances or unique stands occurred (from 1997-1999) with less than 5 hectares of spatial extent. These designations were provided separately from the Mojave Vegetation Polygons because the target standard for the polygons was a minimum mapping unit (MMU) of 5 hectares,

Projected Change in Aridity Index from 2016-2075 for the Colorado Plateau

Future annual aridity index (AI, precipitation divided by potential evapotranspiration [PET]) was calculated from monthly temperature and precipitation data extracted from 10 General Circulation Models from the Coupled-Model Intercomparison Project, Phase 5 (CMIP5) downscaled to 1/8° spatial resolution (Maurer et al. 2007, Bureau of Reclamation 2013). The models were

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Field Data

The Mojave Vegetation field data were collected to provide context for the classification of the Central Mojave Desert into various vegetation classes. The field data consist of five CSV tables, recovered from their original Microsoft Access format, that together describe the vegetative, environmental and geomorphic properties of the Central Mojave Desert at the time of collection, 1997-1

Legacy and lag effects data for the northern Colorado Plateau, USA

This climate and vegetation index dataset was collected from readily available open source data, such as Landsat. The data represents points across the northern Colorado plateau. The vegetation type was defined based on U.S. Geological Survey ReGAP data. Using compositing techniques by season we developed a dataset of lag and legacy for each point. We could then look to understand how both lag...

Geomorphic Change-Sediment Transport Data for Kanab Creek, Arizona USA

These data were compiled to accompany flow modeling work on Kanab Creek near the mouth (USGS gage 09403850). The data include topographic data collected by a remote sensing detection light detection and ranging (LIDAR) system and surveying total station in June 2017, high water marks from six floods from 2011 to 2013, and control points and gage structures. Topographic data include gr
