Bumble bees and flowering plants in Glacier National Park 2023

USGS personnel surveyed bumble bees and flowering plants in and around Glacier National Park during the summer of 2023. These data include 1) a .csv file of all bumble bee - plant interactions observed across surveys and 2) all flowering plants observed in bloom across all surveys.

qPCR detection and quantitative results for Northern Pike (Esox lucius) from environmental (e)DNA samples collected along Miller Creek, Kenai Peninsula, Alaska in February and March of 2024

The dataset contains qualitative detection and quantitative results of Esox Lucius DNA in environmental (e)DNA water samples collected from Miller Creek, Alaska and analyzed with quantitative PCR.

Individual specific hybridization data from the upper Snake River, Wyoming from 2014

Dataset includes individual-specific genetic data describing the extent of hybridization between Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) and rainbow trout (O. mykiss) in Wyoming.

Predicted consequences of detecting Najas minor environmental DNA in Sebago Lake Maine, 2022

U.S. Geological Survey decision analysts and technical experts worked with managers and stakeholders to predict the consequences of alternative actions following environmental DNA detections of invasive Najas minor eDNA in Sebago Lake, Maine, USA. This dataset provides the consequence and model inputs for each of the alternative actions under different levels of uncertainty.

Black bear (Ursus Americanus) spatial capture recapture dataset in and near Glacier National Park, Montana, USA, 2004

Tabular and raster data containing spatial capture recapture records for male and female black bears (Ursus americanus) in Glacier National Park and surrounding landscape collected from June - October 2004 and associated tabular data files required for analysis of data with spatial capture connectivity models and raster data describing the ouput from SCR models. Associated tables and rasters inclu

Glacier Waterton International Peace Park bighorn sheep (Ovis canadensis) habitat selection, 2002-2012

Output of analysis describing habitat selection, the location of contacts and the intersection of the two. Based on GPS collar data from 2002 to 2011.

Glacier Waterton International Peace Park bighorn sheep (Ovis canadensis), 2002-2012

From 2002 to 2011, 94 bighorn sheep were collared to collect GPS locations for approximately a year.

Reach-scale stream and riparian habitat from Nevada, 2022 (ver. 2.0, April 2024)

This dataset was created to assess the status of Lahontan cutthroat trout (*Oncorhynchus clarkii henshawi*) habitat. Surveys were conducted within occupied Lahontan cutthroat trout habitat, as designated by the U.S. Fish and Wildlife Service. Data represent reach-based surveys conducted in accordance with the Lahontan cutthroat trout habitat status assessment (LCTHSA) protocol (USGS). LCTHSA uses

Remotely-sensed vegetation status, trends, and elevation for valley bottoms in Lahontan cutthroat trout (Oncorhynchus clarkii henshawi) suitable habitat in the Great Basin with summary data from 2013-2022

This dataset was created using remotely-sensed information within the valley bottom extent of Lahontan cutthroat trout (*Oncorhynchus clarkii henshawi*) suitable habitat as defined and delineated by the U.S. Fish and Wildlife Service. Each row represents a section of valley bottom for which the attribute was summarized based on information contained in the pixels that overlapped the valley bottom.

Blacklegged tick nymph densities, tickborne pathogen prevalence, and white-tailed deer densities in eight national parks in the eastern United States from 2014-2022

The data presented here are blacklegged tick nymph densities, white-tailed deer densities, and Borrelia burgdorferi (causative agent of Lyme disease) prevalences for eight national parks in the eastern United States from 2014-2022.

Half-meter topobathymetric elevation model and elevation-area-volume tables for Great Salt Lake, Utah, 2002-2016

This topobathymetric elevation dataset of Great Salt Lake includes an assimilated topobathymetric raster comprising interpolated bathymetry from 2005 and 2006 (Baskin, 2005; Baskin, 2006) and QL1 and QL2 lidar from 2016 (Utah Geospatial Resource Center, 2016). The bathymetric dataset was originally published as contour maps. The contours were interpolated to develop a digital elevation model that
