Meteorological Data for Selected Sites along the Colorado River Corridor, Arizona, 2014-2015

These data are records collected from six automated weather stations in operation between January 1, 2014 and December 31, 2015 within the Colorado River Corridor of Grand Canyon National Park and Glen Canyon National Recreation Area. Data collection locations, equipment configurations and methods follow those of the original report (OFR 2014-1247). These files are 4-minute interval data for...

Undiscovered Continuous Gas Colorado Plateau

This dataset is based on U.S. Geological Survey (USGS) resource assessments for “undiscovered” gas resources, which are resources that have not yet been extensively proven by drilling (USGS 2014). Individual resource assessments describe the amount of petroleum resources in units with similar geologic features. We focused on the amount of undiscovered continuous gas because...

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...

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...

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 ground...

Scenario for Impacts to Ecosystem Attributes Colorado Plateau

We assessed the spatial pattern and extent of potential impacts of spatially overlapping high intensity land-use and aridification trends on landscape attributes: crop productivity, soil productivity, vegetation and wildlife habitat, and recreation tourism economy, as well as two ecosystem services: water availability (provisioning service) and spiritual and cultural values (cultural service...

River Valley Sediment Connectivity Data, Colorado River, Grand Canyon

This workbook contains spatial data on the hydrology, sedimentology, and vegetation extent within the Colorado River corridor from 60 to 78 miles (97 to 125 kilometers) downstream from Glen Canyon Dam, Arizona. In combination with the accompanying MATLAB scripts, these data were used to generate the results within the accompanying manuscript (Kasprak et al., Quantifying and Forecasting Changes...

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...

Grand Canyon Whitewater Boater Data, Convergent Validity between Willingness to Pay Elicitation Methods

These data were complied for the primary analysis underlying the results presented in the manuscript associated with these data (see Larger Work Citation). The data was collected from a 2015 survey of private party Grand Canyon boaters. The open document file contains 3 data sheets: 1) variables used in the Table 2 comparison of samples, 2) the core dichotomous choice contingent valuation...

High Intensity Land-use Overlap Colorado Plateau

This dataset represents the spatial overlap in areas with present (cropland, grazing, and recreation), potential (petroleum resources), or projected future (population) high-intensity land-use. The final areas designated as high-intensity land-use represent high intensity relative to the range of values for that variable in this region, either present or future, and do not represent the rate...

BLM Recreation Visitors, 2014, Colorado Plateau

Bureau of Land Management (BLM) field office recreation data for 2014 was downloaded from the Recreation Management Information System (Yuan et al. 1995, Nickels 2003, Leuders 2015). The unit is number of participants in 2014, which was estimated at the scale of an individual BLM Field Office. Leuders, A. 2015. Fiscal year 2015 end-of-year recreation management information system data call....

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...
