One of the most visible signs of climate change is less mountain snow. In the Western U.S., deep snow has historically been a cornerstone of life for many plants and animals. For example, snow can provide denning shelter for certain species like the wolverine, and snowmelt provides dependable water to mountain streams that are home to fish like the bull trout. Yet snow losses driven by warming temperatures are already causing land and water managers to rethink whether certain species can thrive in the future. A recently completed study by this research team helped the U.S. Fish and Wildlife Service investigate whether wolverines will have enough snow to survive in two areas of the Rocky Mountains. In June 2020,...

Amphibians are a group of animals facing especially severe declines due to many factors including climate change and a common pathogen, the amphibian chytrid fungus. To make informed decisions about amphibians, wildlife managers need to identify species facing the greatest threats and the actions that will most effectively minimize impacts of those threats. Although some amphibian species are relatively well-studied, for most, data to inform management decisions are lacking. Therefore, tools to assist managers must be applicable to amphibian species across a range of data availability and susceptibility to climate change and other threats. In this project, researchers will determine which amphibians in the North...

The National Park Service is responsible for managing livestock grazing on 94 locations across the country and several grazing management planning efforts for this work are underway. However, there is a recognized need to update grazing management plans to address potential future effects of climate change on related resources and practices. This is the second phase of a project that is using scenario planning (a strategic planning technique used to inform decision-making in the face of uncertain future conditions) to support grazing management at Dinosaur National Monument. In the first phase of the project (Integrating Climate Considerations into Grazing Management Programs in National Parks), the research team...

Even when faced with uncertainty about future climate conditions, resource managers are tasked with making planning and adaptation decisions that impact important natural and cultural resources. Species distribution models are widely used by both researchers and managers to estimate species responses to climate change. These models combine data on environmental variables (e.g., temperature, precipitation) with field samples of a species’ presence, absence, and/or abundance to project and visualize potential habitat of the species across space and time. However, species distribution modeling software previously developed and supported by USGS (the Software for Assisted Habitat Modeling [SAHM] package for VisTrails)...
