Wyoming Landscape Conservation Initiative (WLCI) research at NOROCK
The Wyoming Landscape Conservation Initiative (WLCI) addresses the impacts of land-use and habitat changes on Southwest Wyoming’s natural resources. This long-term project involves partners from 12 Federal, State, and local natural resource agencies, as well as non-governmental organizations. NOROCK scientists, partners, and scientists from other USGS centers conduct integrated research to support...
Impacts of climate change on habitat quality: plant phenology interactions with animal use and fitness
Weather and climate impact terrestrial wildlife habitat through their influences on plant productivity. Plant phenology – the timing of life-history events such as green-up, flowering and senescence – provides one indicator of the timing and magnitude of productivity. Changes and variability in plant phenology in space and time are indicators of habitat quality, which is a driver of fitness for...
Identification of Fire Refugia in Rocky Mountain Ecosystems of the U.S. and Canada: Development and Application of the Refugium Concept for Biodiversity Conservation over Large Spatial and Temporal Scales
We described the climate space of fire regimes in northwestern North America (Whitman and others 2015), and we are refining an approach to identify fire refugia – areas that do not burn or burn with lower severity through multiple fire events. We continue our collaboration to test the function of refugia for biodiversity conservation under current and future climate and fire scenarios. We continue...

Building Collaboration Between the North Central CSC and Regional Partners Through Liaison Teams
The North Central Climate Science Center (NC CSC) is committed to bringing the best possible climate science to bear in order to inform decisions made by Department of the Interior (DOI) planners and other land and resource managers across the country. To help accomplish this mission, key partnerships have been established between the NC CSC and the DOI Landscape Conservation...
Continued Capacity Building in the North-Central U.S.: Tribal Engagement and PhenoCam Analysis
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...
Remotely sensed elk locations on the National Elk Refuge, Wyoming, 2017-2019 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...

Wind-energy development alters pronghorn migration at multiple scales Wind-energy development alters pronghorn migration at multiple scales
Migration is a critical behavioral strategy necessary for population persistence and ecosystem functioning, but migration routes have been increasingly disrupted by anthropogenic activities, including energy development. Wind energy is the world's fastest growing source of electricity and represents an important alternative to hydrocarbon extraction, but its effects on migratory species...

Eyes on the herd: Quantifying ungulate density from satellite, unmanned aerial systems, and GPScollar data Eyes on the herd: Quantifying ungulate density from satellite, unmanned aerial systems, and GPScollar data
Novel approaches to 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...

Variable effects of wind-energy development on seasonal habitat selection of pronghorn Variable effects of wind-energy development on seasonal habitat selection of pronghorn
In the face of climate change, wind energy represents an important alternative to oil and gas extraction to meet increasing energy demands, but it has the potential to disrupt wildlife populations. Because behavioral adjustments, such as altered habitat selection, are a primary way that long-lived species respond to novel disturbances, we evaluated effects of wind energy development on...

The Wyoming Landscape Conservation Initiative (WLCI) was established in 2007 as a collaborative interagency partnership to develop and implement science-based conservation actions. During the past 11 years, partners from U.S. Geological Survey (USGS), State and Federal land management agencies, universities, and the public have collaborated to implement a long-term (more than 10 years)...

Human activities and weather drive contact rates of wintering elk 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...

Comparative performance and trend of remotely sensed phenology and productivity metrics across the Western United States Comparative performance and trend of remotely sensed phenology and productivity metrics across the Western United States
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...
