Mine density 2014, Colorado Plateau

Mine density at 10 km2 scale calculated with records from the Mineral Resources Data System (USGS 2011). Records are from pre-Hispanic conquest through 2014. USGS [U.S. Geological Survey]. 2011. Mineral Resources On-Line Spatial Data: Mineral Resources Data System (MRDS). https://mrdata.usgs.gov/mrds/. Department of the Interior, Reston, Virginia,...

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,

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...

National Park Service Visitors 2014 Colorado Plateau

Annual visitor records were downloaded for each NPS unit within the study area (Visitor Use Statistics, NPS 2015). NPS [National Park Service]. 2015. NPS Stats: National Park Service visitor use statistics. National Park Service, Department of Agriculture, Washington D.C., USA.

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

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

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

Southern Pacific Pond Turtle Data, Elizabeth Lake, Los Angeles County, California, 2014

These data were compiled to study the effects of severe drought and a concurrent large wildfire on a large population of southern Pacific pond turtles living in a rapidly drying lake. The study was done in collaboration with biologists from Ecorp Consulting in Santa Ana, California with funding from the Desert Tortoise Council. Data were collected in August and September of 2014. This...

Acoustic backscatter—Data and Python Code

These data were compiled for investigating the relationship between acoustic backscattering by riverbeds composed of various riverbed substrates (bed sediment), and for developing and testing a probabilistic model for substrate classification based on high-frequency multibeam acoustic backscatter. The model is described in Buscombe et al. (2017). The data consist of various quantities on...

Population dynamics of humpback chub, rainbow trout and brown trout in the Colorado River in its Grand Canyon Reach: fit and sim input data

These data were compiled to fit an integrated population model of brown trout in the Glen Canyon Reach of the Colorado River and test different hypotheses regarding the driver of brown trout population dynamics. Also, data were compiled as inputs for a model to simulate population dynamics and species interactions among brown trout, rainbow trout and humpback chub in the Colorado River betwee...

Forest Service Visits 2014 Colorado Plateau

We calculated the intensity of recreation visitation in 2014 based on Forest Service (FS) visits reported in the National Visitor Use Monitoring System at the level of a National Forest (English et. al., 2002). Recreation use on FS lands is tracked at five-year intervals (2010–2014), therefore these data represent a rough estimate of potential 2014 visits. English, D.

Central Mojave Desert Vegetation Mapping Project, California, 1997-1999: Plots Points and Repeat Photographs

The Mojave Plots Points data are 1,219 plot locations in the Central Mojave Desert where field data were recorded and repeat photographs were taken from 1997-1999 to provide context for the classification of the Central Mojave Desert into various vegetation classes. The 1,219 plot locations in the plots points shapefile (plots_points.shp) are each assigned a unique identifier called the
