Remotely sensed elk locations on the National Elk Refuge, Wyoming, 2017-2019

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.

Downscaled western bumble bee predicted occupancy for 2020, western conterminous United States.

This data represents occupancy predictions for western bumble bee in 2020 across the western conterminous United States. This product is a 30-meter resolution downscaled version of previously published occupancy layers for the western bumble bee. For more information on original publications, see the publication listed in the Larger Works Cited Section.

Neonicotinoid nitroguanidine group insecticide application rates estimated across the western conterminous United States, 2008 to 2014

These data represents annual estimates of neonicotinoid nitroguanidine group insecticide application rates across the western conterminous United States from 2008 to 2014. This product contains seven raster layers (appearing as separate bands in a multi-band raster). Each band represents one year of the data beginning in 2008. Estimates are generated by pairing crop specific application rates of neonicotinoids with fine scale crop data obtained from the CropScape cropland data layer. Application units are kilograms per hectare. Further details on the methods used to generate this product are described in: Douglas, M.R., Baisley, P., Soba, S., Kammerer, M., Lonsdorf, E.V. and Grozinger, C.M., 2022. Putting pesticides...

Human activities and weather drive contact rates of wintering elk

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...

Eyes on the herd: Quantifying ungulate density from satellite, unmanned aerial systems, and GPS collar data

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...
