Modeled habitat suitability for Erigeron rhizomatus (Zuni fleabane)

This raster presents the final outputs from a VisTrails/SAHM workflow to model the potential distribution of Zuni fleabane (Erigeron rhizomatus) in northwestern New Mexico. These models utilized field data of spatially thinned occurrence locations and random background locations. We included a suite of predictors related to soils, topography, vegetation cover, and geology. Details about both occurrence data and predictor inputs are included in the associated manuscript and Source Info section of this metadata. We developed models using five algorithms with VisTrails: Software for Assisted Habitat Modeling [SAHM 2.1.2] (Morisette et al., 2013), and combined these to create an ensemble of models. The resulting raster...

Characteristics, presence of erosional features, and cover of vegetation and bare ground on fields formerly enrolled in grassland, wetland, and wildlife practices of the Conservation Reserve Program in the central and western United States from 2017 to 2018

Data included in this data set are from edge-of-field surveys that recorded the presence of erosional features, cover of vegetation and bare ground, and management activities (e.g., haying) on 1092 fields that had expired from three types of conservation practices (grassland, wetland, and wildlife) in the Conservation Reserve Program. Field sampling data were recorded across six US Department of Agriculture Farm Production Regions (Corn belt, Lake states, Mountain, Northern plains, Pacific, Southern plains) from 2017 to 2018. The study area encompassed all or part of 14 states: Washington, Oregon, Idaho, Montana, North Dakota, South Dakota, Minnesota, Iowa, Missouri, Colorado, Nebraska, Kansas, Oklahoma, and Texas....

Modeled habitat suitability for five rare plants (Aliciella formosa, Sclerocactus cloverae, Townsendia gypsophila, Astragalus ripleyi, and Cymopterus spellenbergii) in New Mexico

This data bundle contains the final outputs from a VisTrails/SAHM workflow to model the potential distribution of 5 rare plants (Aliciella formosa, Sclerocactus cloverae, Townsendia gypsophila, Astragalus ripleyi, and Cymopterus spellenbergii) in northern New Mexico. These models utilized field data of spatially thinned occurrence locations and random background locations or random plus absence locations for the 5 species. Predictors included but were not limited to soil characteristics, topography, percent tree cover, bare ground, and continuous heat-insolation load index rasters. Details about both occurrence data and predictor inputs are included in the associated manuscript and Source Info section of this metadata....

Land Disturbance Associated With Oil and Gas Extraction in Southwestern Wyoming, 2012

Gas field infrastructure elements contributing to land disturbance located in four gas fields (Continental Divide – Creston – Blue Gap (CCB), Jonah, Moxa Arch, and Pinedale Anticline Project Area) in southwestern Wyoming were collected as polygon features in ArcGIS. Classes included four types of roads, well pads (active and abandoned), residual disturbance associated with the well pads, buried utilities, disturbances associated with non-well pad industry facilities, and areas of general disturbance associated with the installation and operation of gas wells not fitting one of the other disturbance class definitions.

Pygmy rabbits (Brachylagus idahoensis) are a Species of Greatest Conservation Need in Wyoming. They are designated as such because they are sagebrush obligates and entrained in the health and intactness of sagebrush steppe landscapes. Southwest Wyoming, where pygmy rabbits occur, has become an epicenter of domestic oil and gas exploration and this activity contributes to loss and fragmentation of sagebrush habitats. This tabular file that was used for analysis contains the following data/information: survey site, plot, and gas field; pygmy rabbit occupancy status; UTM coordinates associated with occupancy (dithered to protect pygmy rabbits from further disturbance); an index value indicating amount of fresh pygmy...
