A total of 200 soil samples were collected in the Greater Yellowstone Ecosystem in Grand Teton National Park and the National Elk Refuge in July 2019 for chronic wasting disease (CWD) monitoring purposes. To collect samples from locations where ungulates are most likely to be shedding or encountering CWD, we targeted elk collar data locations, known migration routes of mule deer and elk, and areas where yearly elk supplemental feeding generally occurs on the National Elk Refuge. We sampled 10 transects in Grand Teton National Park and 10 transects in the National Elk Refuge, each 1,000 meters in length. We collected soil samples every 100 meters along the transect for a total of 10 samples per transect. Terra Core Samplers were used to collect 10 grams of surface soil at each sample location. Here we provide the transect identifier, transect name, sample point name, GPS location where each soil sample was collected, and the date when each sample was collected.

Sixty-eight monitoring plots within the Browns Park National Wildlife refuge in Northwest Colorado were surveyed in the Summer of 2007 and 2021 for vegetation-community changes after grazing cessation in 1986. Surveys consisted of line-point intercept measurements at 0.5m intervals along three 15-m transects arranged in a spoke around plot center at each plot location.

In 2016, a multidisciplinary team from the U.S. Geological Survey Wyoming-Montana Water Science Center, National Park Service, The Centers for Disease Control and Prevention, and Montana State University’s Department of Microbiology and Immunology in cooperation with the Teton Conservation District, initiated a small study to document the presence or absence of Naegleria fowleri at several hot springs in Grand Teton National Park/John D. Rockefeller, Jr. Memorial Parkway. Over four sampling events in 2016-2017, Naegleria fowleri was detected in several of the Grand Teton National Park/John D. Rockefeller, Jr. Memorial Parkway hot springs for the first time. Additionally, the team found that the prevalence of Naegleria fowleri may be subject to seasonal fluctuations.

Non-biological data (habitat assessment, logger information, water quality data) for spring macroinvertebrate inventory sites at Shenandoah National Park. Dataset as delivered.

Remotely sensed elk locations from satellite imagery, Unmanned Aerial Systems (UAS) imagery, and Global Positioning System (GPS) collar locations were collected during the winter of 2018 and the winter and spring of 2019 at the National Elk Refuge in Jackson, Wyoming. The dataset associated with this data release provides the source, date, time, latitude, and longitude of elk locations and the type of analyses the locations were used in as reported in the accompanying manuscript by Graves and others 2021; XXXXXXXXXXX.

Geodatabase representing the sample design for the North Coast and Cascades Network (NCCN) elk monitoring project at Lewis and Clark National Historical Park (LEWI). The goal for the elk monitoring project is to detect changes in the magnitude and spatial patterns of elk use of landscapes at several spatial and temporal scales within, and adjacent to, the Fort Clastop unit of Lewis and Clark National Historical Park (LEWI). The geodatabase is the spatial representation of elk pellet survey plot locations and standard road driving routes, with tenth mile reference markers, used to conduct elk surveys. Changes in elk relative use and the proportion of area occupied (PAO) by elk will be based on pellet group surveys conducted in the Fort Clatsop unit of LEWI. We will monitor trends in the relative use by elk in winter through the estimation of pellet group density as measured during late winter surveys each year. We will infer trends in elk viewing opportunities in selected areas adjacent to the Fort Clatsop unit by monitoring the rate at which elk are sighted in roadside surveys on specified routes. The road survey sighting rate is a direct index to the rate that park visitors driving the selected set of roads would be expected to see elk. By recording the seasonal patterns of elk herd sightings we will document trends in elk viewing opportunities for visitors during different seasons.

The data is from a multi-year study of the impact of an unidentified defoliator. Collected data include: diameter, height, crown class, percent live crown ratio, percent crown density, percent foliage transparency, percent dieback, percent defoliation, number of fruit clusters, a vigor rating, visible damage type(s) and new growth measurement (Shoot_Length). Crown ratings follow USDA Forest Service Forest Health rating system.
