Data and Tools
Our interdisciplinary, integrated science teams develop various data sets and tools in support of the USGS mission areas. These tools then aid natural resource managers in decision making and support of the complex issues they face in today's world.
Migrating Bird Survey Data along the San Pedro River and its Tributaries, Southeastern Arizona, 1989-1994
Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minute
Hierarchically nested and biologically relevant monitoring frameworks for Greater Sage-grouse, 2019, Nevada and Wyoming, Interim
We developed a hierarchical clustering approach that identifies biologically relevant landscape units that can 1) be used as a long-term population monitoring framework, 2) be repeated across the Greater sage-grouse range, 3) be used to track the outcomes of local and regional populations by comparing population changes across scales, and 4) be used to inform where to best spatially
Bat Occupancy Model Predictions for Colorado, acoustic data from 2016-2017
We analyzed detection/non-detection data from acoustic surveys of bat species in Colorado during the summers of 2016 and 2017. The goal of this analysis is to create species distribution maps estimating the probability of occupancy across the state for each species. We fit a community occupancy model using both years of data from all the available species. Spatially explicit covariates were...
Estimated habitat suitability for the American burying beetle using land cover classes in the Southern Plains
Potentially suitable habitat for the American burying beetle (Nicrophorus americanus) was identified within their Southern Plains range. The American burying beetle (ABB) is listed as endangered under the Endangered Species Act, but in 2019 the U.S. Fish and Wildlife Service proposed to reclassify this species as threatened. We applied a deductive model for the ABB that identified poten
Fire resistance trait data for 29 western North American conifer species
The data represent a collection of six different traits related to conifer fire resistance morphology and flammability. These traits have been combined into a single fire resistance score, contained as a variable within the data table. The raster file shows the distribution of this variable across space, specifically western North America.
Removal count data of Veiled Chameleons on Maui, 2002-2012
The data set consists of 3 spreadsheets: counts, efforts, and location that detail the 10-year removal effort of invasive Veiled Chameleons (Chamaeleo calyptratus) on the island of Maui. Recorded are the number of lizards removed from each site, the level of search effort at each site, and the centroid location of each sampled site.
Measurements of milkweeds and associated arthropods at Hastings Preserve, California in 2013
Monthly measurements of milkweed stems were made in 2013 at Hastings Natural History Reservation. At the same time, arthropod communities were measured associated with each milkweed stem. Treatments were conducted in which a subset of milkweed stems were damaged each month.
Paleoecological data from The Loch and Sky Pond, Rocky Mountain National Park
Diatom taxonomy, carbon and nitrogen stable isotope values, and algal pigment data from lake sediment layers dating back to 1600 Common Era (CE) for Sky Pond and The Loch in Rocky Mountain National Park.
Data on interannual variability of seed production, nutrient, and weather for 219 plant species
We calculated estimates describing interannual variation in seed production for series of long-term seed or fruit production in 219 plant species. For each plant species, we compiled estimates of foliar nutrient concentrations as well as productivity and weather at the site of observation. Data was compiled in order to test whether interannual variation in seed production was greater in...
Radiogenic strontium isotope data for non-native walleye otoliths collected from select areas of the Upper Colorado River Basin
This dataset includes radiogenic strontium isotope compositions of non-native walleye otoliths collected from select areas of the Upper Colorado River Basin (UCRB). Strontium isotope data have been widely used to assess natal areas for a variety of fish species. Following on previous work, this project sought to fill data gaps for walleye collected from the Colorado River (river miles 1
Predicted (1989-2015) and forecasted (2015-2114) estimates for rate of change and recovery of sagebrush (Artemisia spp.) following energy development in southwestern Wyoming, USA
In 'Predicted (1989-2015) and forecasted (2015-2114) rate of change and recovery of sagebrush (Artemisia spp.) following energy development in southwestern Wyoming, USA', we provide spatially- and temporally-explicit maps of predictions for the rate of change and time to recovery and percent recovery of sagebrush cover after 100 years (Monroe et al. In revision). The rast
Active channel in the Lower Virgin River after a 40 yr flood (December 2010)
Active channel as defined by remote sensing after (2011) a 40 year return period flood (December 2010) within the lower Virgin River, Nevada.
Vegetation, topography and sediment quality in the Lower Virgin River 2010-2012
Plant composition, geomorphic conditions and sediment properties before (2010) and after (2012) a 40 year return period flood (December 2010) at multiple transects within four reaches in the lower Virgin River, Nevada. The data contains four .csv files: localization (UTM coordinates of the transects), vegetation and geomorphology, species codes and sediment quality
