False positive occupancy analysis predictions with model uncertainty based on summertime data provided to support the status assessment (SSA) for Myotis septentrionalis (MYSE). The objectives outlined by the Fish and Wildlife Service’s SSA team were to estimate summertime distributions across the entire species range. Statistical analysis included five types of response data requested from the North American Bat Monitoring Program database (NABat): automatically identified stationary acoustic calls, manually vetted stationary acoustic calls, automatically identified mobile acoustic calls, manually vetted mobile acoustic calls, and capture records. Statistical analysis was for the summertime distribution modeling,...
Data include a mark-recapture dataset of cutthroat trout. Data indicate date of marking and recapture, size at marking, growth, basin data were collected, year data were collected, and unique identification tags.
Quantitative PCR data from mesocosm experiments and field evaluations comparing coarse filter-large water volume environmental DNA samples vs. fine filter-small water volume environmental DNA samples for detection and quantification of rainbow trout (Oncorhynchus mykiss) and bull trout (Salvelinus confluentus) DNA. Mesocosm experiments took place at the US Fish & Wildlife Service's Creston Fish Hatchery in Montana, 2016. Field surveys took place in the Flathead River basin of Montana, 2016.
The data represent counts of Rocky Mountain Tailed Frog larvae from 8 streams in Glacier National Park, Montana. Each stream was surveyed during 5 different years. We originally sampled the eight streams during June 2001 to evaluate a time-constrained method for potential inclusion in a monitoring program. We sampled streams by turning rocks and disturbing the substrate in front of D-frame nets for 250 min, with surveyors moving progressing upstream. Surveyors focused on areas of optimal habitat (e.g., turbulent water, coarse substrates) to increase the likelihood of capturing larvae. Two surveyors sampled simultaneously for 5-min each (making one 10-min period) and called out captures to a data recorder. Surveyors...

A raster surface identifying hotspots of conservation priority based on 375 location records (89 unique geographic locations) of 28 species of Carnivora in Peninsular Malaysia. Hotspot analysis was conducted by calculating the Getis-Ord Gi* (pronounced G-i-star) statistic, using IUCN Red List status rank for each species as a weighting variable. Raster cell values represent a kernel density of z-scores measuring the statistical significance of clustering or dispersion of species of conservation concern. Areas of high clustering (high z-scores) correspond to areas on Peninsular Malaysia where carnivore communities of conservation concern are more likely to persist, and delineate priority regions for carnivore conservation....

These data represent occupancy estimates for western bumble bee across the western conterminous United States. This product contains five raster layers (appearing as separate bands in a multi-band raster). The first two bands represent the predicted occupancy of western bumble bee in 1998 and 2020. We modeled western bumble bee occupancy as a function of climate and land cover. The last three bands represent future occupancy projections of western bumble bee into the mid-century (2050s). The future projections cover a range of expected changes in climate and land cover and are ranked as best-case (band 3), middle-case (band 4), and worst-case (band 5).

Calcium and pH data collected at lake, reservoir, impoundment and stream site types in the Columbia River Basin. These data were downloaded from the National Water Quality Portal on 03/31/2022 and cleaned and filtered. We limited calcium data to just those values that described dissolved calcium and total calcium concentrations. We included total calcium to maximize the amount of data available for this risk assessment; dissolved and total calcium are strongly correlated since dissolved calcium is a constituent part of total calcium. We then cleaned these data by filtering to just those entries associated with water (‘ActivityMediaName’ = Water); dropping rows with ‘NA’ values; removing white spaces; removing duplicated...

The data were collected every year from 2011 until 2017 at the Clarno unit of the John Day Fossil Beds National Monument. The areal plots were placed following a random selection of locations based on the GRTS algorithm. There was a fire documented in 2011 and interest is in assessing whether there is evidence of cheatgrass distribution or abundance increasing in the monument post-fire.

This dataset contains daily fractional snow covered area (fSCA) at 30-m spatial resolution from August 1, 2015 - May 15, 2020 (five winters) for the National Elk Refuge in Wyoming, USA. The following summary statistics are also included: date of snow accumulation, date of snow melt, number of days in year with snow on ground, and percentage of "winter days" in year with snow on ground. The SNOWARP algorithm was used to produce these data (Berman et. al., 2018; see full citation below), in which dynamic time warping fuses together MODIS MOD10A1 with Landsat level-3 fSCA, resulting in daily 30-m fSCA estimates. All dates correspond to winter day of year (WDOY), which runs between August 1 - July 31 each season and...
The spread of white-nose syndrome (WNS) across the eastern United States has raised conservation concerns and provided motivation for efforts to monitor the impacts of this disease. Currently, WNS has not yet been detected in Montana, or any other western state besides Washington, and it is unknown how severe it will impact species in this region once it arrives. Within an occupancy model framework, we analyzed mist netting and acoustic records for eight bat species in Montana to estimate baseline distributions across the state prior to the arrival of WNS. Heterogeneity in the probabilities of occupancy for each species was explained with covariates for forest cover (%), elevation, ruggedness, and average degree...

This dataset includes processed tree ring data from avalanche paths in southeast Alaska, USA. The data were processed in three distinct phases that resulted in this dataset: collection, processing, and avalanche signal analysis. This dataset consists of samples from 434 cross sections from 426 unique trees throughout six avalanche paths in the study region. This resulted in 2706 identified growth disturbances (GDs) due to avalanches.
Many aspects of recurring plant developmental events – vegetation phenology – are measured by remote sensing. By consistently measuring the timing and magnitude of the growing season, it is possible to study the complex relationships among drivers of the seasonal cycle of vegetation, including legacy conditions. We studied the role of current and legacy climate, and contextual factors on the land surface phenology of the U.S. Northern Great Plains. Specifically, we used annual and seasonal climate variables (e.g., temperature, precipitation, growing degree days, and vapor pressure deficit) covering the current year and the past four years derived from the PRISM climate dataset. We also included soils, disturbance,...
The Wyoming statewide time-stamped oil and gas wells shapefile was developed to provide a historical perspective of drilling activity for the Wyoming Landscape Conservation Initiative (WLCI). This product approximates start and stop dates for each well in Wyoming based on database attributes. These data originated from the Wyoming Oil and Gas Conservation Commission (WOGCC). Data represent 120 years of oil and gas drilling (1900 to 2020) and will facilitate a landscape-level approach to integrated science-based assessments, resource management, and land-use decision making. Oil and gas data from WOGCC were used in a dataset previously published by Biewick in 2010 (https://pubs.usgs.gov/ds/625/). This product expands...

Sagebrush ecosystems and wildlife that depend on them are under pressure from development, changing climate, as well as natural and human-caused disturbance. Mule deer (Odocoileus hemionus) are of particular concern due to population declines across many western states. We initiated a study to evaluate landscape-level changes ( disturbances, habitat treatments, development, and climate change) in Wyoming. This dataset contains age ratios (the number of juveniles to adult female mule deer) for 36 herd units in Wyoming, USA from 1985-2019. Age ratios provide a consistent metric of population demographics, including an index of recruitment (survival rate of young), which can be a sensitive metric of population change....
