Terrestrial Development Index for the western United States:1-kilometer moving window

The Terrestrial Development Index (TDI) quantifies the level of development (urban, agriculture, energy and mineral extraction and transmission, and transportation) based on the surface disturbance footprint. TDI values range from 0 to 100% and represent the total percentage of land surface occupied by the development footprint within a 1-kilometer (km) radius moving window.

Riparian vegetation, topography, and ground cover constituents along the Upper Colorado River near Moab, UT (2010-2017)

The data release presents observations of riparian vegetation, topography, and ground cover in two river reaches of the Upper Colorado River within a river segment extending 208 river kilometers (rkm), from near the Colorado/Utah border to the confluence of the Green River. Methods included field observations and analysis of the plant community five times over eight years in the fal

Point Locations of Radio-collared female northern Yellowstone mule deer

This data set provides details on the date and time of relocations or radio-collared female northern Yellowstone mule deer along with the UTMs of the location. It also includes information on whether the location was obtained from a fixed-wing aircraft or from ground triangulation, whether the location was plotted on a map or obtained by use of a GPS unit in the aircraft, the estimated accur...

Oil and gas development potential in the US Intermountain West.

We created a probabilistic classification model using the nonparametric machine learning technique 'Random Forests' for oil and gas development potential from low (0) to high (1) across the western US. The six predictor variables used in the model were: geophysical data showing aeromagnetic, isostatic gravity, and Bouguer gravity anomalies, geology, topography and bedrock d

Brown Treesnake counts during visual encounter surveys at three walking paces, Guam 2016

We evaluated three walking paces to estimate (1) how snake detection rate per unit distance changes with increasing pace, and (2) how total number of snakes found by the end of a night of surveying varies with pace when the amount of surveying time per night is held constant. For a “fast” pace we searched the 220 meter-long transect in 10 minutes, corresponding to a wa

Visual Surveys Rapid Response Saipan 2016

Nocturnal visual encounter survey data conducted by 29 searchers over 17 transects obtained during a Brown Treesnake rapid response deployment to island of Saipan in 2016. Surveys took place in the vicinity of the Saipan airport and Dandan village (ca. 15.127°N, 145.735°E) from 06 January to 13 March 2016, 6–7 nights/week but with a break in surveying from 26 January t

Airsoft electric gun evaluation on Brown Treesnakes, Guam, 2016

The data set consists of 2 spreadsheets from Airsoft Electric Gun (AEG) trials on brown treesnakes. AEG snake wound data contains AEG results from guns equipped with 0.39 gram ammunition (plastic pellets ) that were fired at dead and live snakes from distances of 4, 8, and 12 m to measure tissue-penetration depth, and noted if (a) the pellet was lodged inside the peritoneal cavi

Brown Treesnake visual survey and radiotelemetry data, Guam 2015

The dataset consists of two spreadsheets that contain brown treesnake data (location, perch taxa, perch height, time of detection, whether visible or not, and size of snake) collected during both visual surveys and radio telemetry within a 55-ha enclosure on Guam.

Precipitation and acoustic monitoring results associated with Arizona 1 and Pinenut uranium mines collected 2015-2016

Acoustic monitoring stations were comprised of Wildlife Acoustics SMBAT2+ bat detectors powered by a 6v 36 AH (Powersonic, Model PS-6062NB) external battery and charged by a 6v solar panel (Brunton Solarflat) with a 6/12 voltage regulator (Rogue Engineering Inc.). Detectors were programmed to turn on at 1800 hours and monitor continuously throughout the night when triggered auto

Data on the impacts of garlic mustard from a weeding experiment in Pennsylvania 2006-2016

Data were collected on the abundance of plants in a 10-year weeding experiment of garlic mustard, located at Trillium Trails Park in Pennsylvania. Garlic mustard was weeded annually to suppress its abundance, and the impacts of garlic mustard were measured based on the response of the plant community to garlic mustard weeding. Because garlic mustard is known to suppress mycorrhizal fungi,...
