These raster data represent the results of a case study in Arizona on how vertebrate richness metrics can be used with existing state and federal guidance in wind and solar energy facility siting. Each of the four geodatabases (see Cross References) contain eight native terrestrial wildlife group models in Arizona: 1) all vertebrates, 2) amphibians, 3) reptiles, 4) birds, 5) mammals, 6) bats, 7) raptors and 8) long-distant migratory birds. An XML workbook is included that lists all terrestrial native vertebrate species in Arizona which cross-walks these species to the name of the National Gap Analysis Project species distribution model.

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 (cover) and sediment movement at two field sites, one a stabilized sand sheet (SS) and the other on the ridge of a sand dune (SD). The data also represent a growth chamber assessment of the soil and litter seed bank from representative samples take at the two field sites.

The U.S. Geological Survey provides a wide range of scientific information to an even wider group of stakeholders. Understanding what capacities are needed and if and or where these capacities exist across the USGS landscape is critical in moving science to the next level of use, implementation, and visualization. The concept behind the groups organized to conduct and interpret the survey that collected these data took advantage of the USGS’s position as a science organization with expertise spanning a wide range of science disciplines, stakeholders, and responsibilities. A survey was conducted of USGS employees (Sep 20-Nov 20) to get a current sample of the capacities that exist across the USGS.

These data were compiled in support of the 'Predicting the next high-impact insect invasion: Elucidating traits and factors determining the risk of introduced herbivorous insects on North American native plants' project, supported by the U.S. Geological Survey John Wesley Powell Center for Analysis and Synthesis. The project working group compiled data for non-native insects herbivorous on three or fewer North American conifer families. Data were synthesized from existing resources for a variety of insect traits, traits of their North American conifer host trees, divergence time between the North American host trees and the host tree in the insects' native range, and native insects that feed on the same North American...

These data were compiled to assess potential changes in the climatic suitability for 66 species (dominant and associate plant species) and forecast climate exposure for 29 major plant communities within major plant communities in the southwestern United States. An objective of our study was that species within plant communities have unique climate suitability signatures and forecast changes in climatic suitability will not be uniform within the species respective communities or among species within the community. The climate suitability spatial models were developed under a modern baseline (1960-90) and future climate scenario (2041-2060) using Maxent and WorldClim temperature and precipitation variables.

These data were compiled for the U.S. Fish and Wildlife Service to assist them with updating the current status of the species Bartram's Stonecrop (Graptopetalum bartramii). Objective(s) of our study were to survey selected sites within the of Bartram's Stonecrop for future management and protection. These data represent summary population counts at selected known sites for the Federally listed Threatened plant species, Bartram's Stonecrop (Graptopetalum bartramii). These data were collected in the southern Arizona portion of the species' range, stratified across Sky Island Mountain ranges from the Rincon Mountains south to the Atascosa Highlands, just north of the Mexican border. Sites were selected to represent...

Stakeholder science needs were determined by reviewing more than 200 recently published literature items and web pages from Colorado River Basin (CRB) stakeholders. These stakeholder communications were used to characterize over 400 stakeholder science needs by reviewing their priorities, strategies, issues, missions, and concerns related to drought in the CRB. Members of the CRB Integrated Science Pilot Project team identified each of the stakeholder’s science needs and categorized the needs based on science themes and science topics that the needs address in the landscape. The terms used as science topics were initially created by Pilot Project team members but then later were cross-walked to match terms in the...

These data were compiled in support of the 'Predicting the next high-impact insect invasion: Elucidating traits and factors determining the risk of introduced herbivorous insects on North American native plants' project, supported by the U.S. Geological Survey John Wesley Powell Center for Analysis and Synthesis. The project working group compiled data for non-native insects herbivorous on one North American hardwood (i.e., woody angiosperm) family. Data were synthesized from existing resources for a variety of insect traits, traits of their North American hardwood host plants, divergence time between the North American host species and the host species in the insects' native range, and native insects that feed...

The U.S. Geological Survey (USGS) Data at Risk (DaR) team partnered with the USGS Southwest Biological Science Center (SBSC) to preserve and release tabular data, shapefiles and field photographs of the Central Mojave Desert from 1997-1999. The data were originally collected as part of an effort through the Desert Managers Group (DMG) to develop scientific information on the distribution and characteristics of vegetation in the eastern Mojave Desert of California. This data preservation effort recovers information from obsolete geospatial files, database files, and field photographs and releases it all in open-source formats. The data made available in this release provide historic context on the species composition...
