Remotely sensed elk locations were derived from satellite and Unmanned Aerial Systems (UAS) imagery collected during the winter of 2018 and the winter and spring of 2019 at the National Elk Refuge in Jackson, Wyoming and compared to locations from Global Positioning System (GPS) collars from 2017 - 2019. This data release provides the source, date, time, latitude, and longitude of elk locations and the type of analyses the location data were used for in the accompanying manuscript by Graves and others 2021. DOI will be provided once supplied by the journal.
Vegetation phenology and productivity play a crucial role in surface energy balance, plant and animal distribution, and animal movement and habitat use and can be measured with remote sensing metrics including start of season (SOS), peak instantaneous rate of green-up date (PIRGd), peak of season (POS), end of season (EOS), and integrated vegetation indices. However, for most metrics, we do not yet understand the agreement of remotely sensed data products with near-surface observations. We also need summaries of changes over time, spatial distribution, variability, and consistency in remote sensing dataset metrics for vegetation timing and quality. We compare metrics from 10 leading remote sensing datasets against...

Wildlife aggregation patterns can influence disease transmission. However, limited research evaluates the influence of anthropogenic and natural factors on aggregation. Many managers would like to reduce wildlife contact rates, driven by aggregation, to limit disease transmission. We develop a novel analytical framework to quantify how management activities such as supplemental feeding and hunting versus weather drive contact rates while accounting for correlated contacts. We apply the framework to the National Elk Refuge (NER), Wyoming, USA, where the probable arrival of chronic wasting disease (CWD) has magnified concerns. We used a daily proximity index to measure contact rates among 68 global positioning system...

The mixed mountain shrub community is one of the WLCI priority habitat types and is associated with numerous WLCI conservation priority areas and habitat projects. The current extent and condition of mountain shrub patches is unknown in most of the WLCI region; thus, trends in their condition and mechanisms driving those conditions are also unknown. Ongoing monitoring data from selected stands indicate an overall decline in this community type. Hypotheses as to what is causing the decline range from persistent drought to herbivory and, possibly, factors associated with increased energy development. Our long-term objectives are to measure and map the current conditions and distribution of mixed mountain shrub communities...
Novel approaches for quantifying density and distributions could help biologists adaptively manage wildlife populations, particularly if methods are accurate, consistent, cost-effective, rapid, and sensitive to change. Such approaches may also improve research on interactions between density and processes of interest such as disease transmission across multiple populations. We assess how satellite imagery, unmanned aerial systems (UAS) imagery, and Global Positioning System (GPS) collar data vary in characterizing elk density, distribution and count patterns across times with and without supplemental feeding at the National Elk Refuge (NER), Wyoming, USA. We also present the first comparison of satellite imagery...

U.S. Geological Survey Science for the Wyoming Landscape Conservation Initiative: 2014 annual report
This is the seventh report produced by the U.S. Geological Survey (USGS) for the Wyoming Landscape Conservation Initiative (WLCI) to detail annual activities conducted by the USGS for addressing specific management needs identified by WLCI partners. In FY2014, there were 26 projects, including a new one that was completed, two others that were also completed, and several that entered new phases or directions. The 26 projects fall into several categories: (1) synthesizing and analyzing existing data to identify current conditions on the landscape and using the data to develop models for projecting past and future landscape conditions; (2) monitoring indicators of ecosystem conditions and the effectiveness of on-the-ground...

Weather and climate influence plant productivity, which in turn influences wildlife habitats and behaviors (Monteith and others, 2011). Monitoring plant phenology (such as the timing of green-up, flowering, or senescence) reveals patterns that can serve as indicators of habitat condition and quality. Climate change may alter phenology patterns and plant species composition, which could affect the availability and quality of forage and cover for WLCI species of concern, such as elk, mule deer, pronghorn, greater sage-grouse, and livestock. This project entails monitoring plant phenology to address the WLCI management need for monitoring and evaluating the effectiveness of habitat-management activities. Our work also...
Climate change is poised to alter natural systems, the frequency of extreme weather, and human health and livelihoods. In order to effectively prepare for and respond to these challenges in the north-central region of the U.S., people must have the knowledge and tools to develop plans and adaptation strategies. This project was a continuation of an effort begun in 2013 to build stakeholders’ capacity to respond to climate change in the north-central U.S. During the course of this project, researchers focused on two major activities: Tribal Capacity Building: Researchers provided tribal colleges and universities with mini-grants to develop student projects to document climate-related changes in weather and culturally...

A continuous 30m raster Digital Elevation Model (DEM) for the Great Northern Landscape Conservation Cooperative (GNLCC) study area. This DEM was complied for analysis of topographic effects on climate within the GNLCC study area, as a part of the GNLCC Fire Refugia Project. The DEM was complied from USGS National Elevation Dataset (NED) (http://ned.usgs.gov/), the British Columbia Gridded Digital Elevation Model Product (http://geobc.gov.bc.ca/base-mapping/imagery/products/gridded.html), and the NASA ASTER GDEM (http://asterweb.jpl.nasa.gov/gdem.asp/), mosaicked, and sinks were filled in ArcGIS.
The Liaison Project increased communications between the North Central Climate Science Center (NC CSC), other USGS Science Centers and potential collaborators including active members of the four Landscape Conservation Cooperatives (LCC) included in the NC CSC area. The project was initiated with listening sessions to determine partners’ interest in liaising with the NC CSC, and USGS liaison proposals were selected based on demonstrated ability to continue and initiate relationships with state, federal, tribal, university and other partners. Increased communications has resulted in activities to co-produce knowledge to support management decisions that are impacted by climate.

We will develop an approach to identify fire refugia in Rocky Mountain ecosystems of the U.S. and Canada then test the function of refugia for biodiversity conservation under current and future climate/fire scenarios (Fig. 1). Our products will be designed to inform decision-making in land/easement acquisition, identification of critical areas for maintaining landscape and process connectivity/permeability, and extension of the temporal context for spatial conservation decision making. The approach will be testable for transferability to other locations and ecosystems.
