Migratory ungulates are susceptible to effects of development along their migration corridors. For example, impermeable barriers such as tall fences preclude movements of migratory populations. Most forms of development in the West, however, represent semipermeable barriers, and their influences on migration remain unclear. This study entails using fine-scale mule deer movement data to evaluate the influence of anthropogenic barriers on the animals’ migratory behaviors. Our efforts include evaluating the rate of travel, duration of stopovers, and route fidelity of deer migrating across a gradient of development in Southwest Wyoming. In FY2014, we analyzed mule deer movement metrics and use of migration stopover...

Many ungulate populations in the Rocky Mountains are predicted to respond to declining snow levels and increased drought, though in ways that remain uncertain. This project investigated how climate change may affect the abundance of Rocky Mountain ungulates, their migration patterns, the degree to which they transmit diseases to livestock, and their herbivory impact on aspen. To complete this work we brought together a team of USGS and University scientists with experience, data, and strong agency collaboration that enabled us to quantify climate impacts and deliver products useful for wildlife managers.
This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 1 (Kauffman et al. 2020) and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations. This data release provides the means for ungulate migrations to be mapped and planned for across a wide variety of landscapes where they occur. Due to data sharing constraints of participating agencies, not all the files that underlie the mapped migrations included in the report have been released. Data can be viewed at: https://westernmigrations.net. Data in this archive can be downloaded two ways. To download...

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...
Abstract (from http://link.springer.com/article/10.1007%2Fs00442-015-3296-4): Climate plays a fundamental role in limiting the range of a species, is a key factor in the dynamics of large herbivores, and is thought to be involved in declines of moose populations in recent decades. We examined effects of climate and growing-season phenology on recruitment (8–9 months old) of young Shiras moose ( Alces alces shirasi) over three decades, from 18 herds, across a large geographic area encompassing much of the southern extent of their range. Recruitment declined in 8 of 18 herds during 1980–2009, whereas others did not exhibit a temporal trend (none showed a positive trend). During those three decades, seasonal temperatures...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
