This project was designed to use the combined strengths of the cooperators to address their concerns stemming from the degradation of arid environments in the Great Basin. The project aimed to identify the regional ecological and social costs and benefits of both immediate hydrologic modifications (low-profile constructed dams) and longer-term restoration of beavers (Castor canadensis) to these landscapes. Use of these techniques by ranchers and managers of public lands depends on these costs and benefits as well as social context and attitudes; the project aimed to assess these as well. Finally, implementation of hydrologic modifications depends on communication of benefits and costs to stakeholders who may choose...

Climate change is one of the most pressing issues facing natural resource management. The disruptions it is causing require that we change the way we consider conservation and resource management in order to ensure the future of habitats, species, and human communities. Practitioners often struggle with how to identify and prioritize specific climate adaptation actions (CAAs). Management actions may have a higher probability of being successful if they are informed by available scientific knowledge and findings; a systematic review process provides a mechanism to scientifically assess management questions. By evaluating specific actions on scientific knowledge and findings, we may be able to increase management...

Wildfires are one of the greatest threats to human infrastructure and the ecosystem services humans value in the western US, but are also necessary in fire-adapted ecosystems. Wildfire activity is widely projected to increase in response to climate change in the Northwest, but we currently lack a comprehensive understanding of what this increase will look like or what its impacts will be on a variety of ecological and hydrologic systems. This project addressed one critical part of those impacts: the islands of unburned vegetation within wildfires. Unburned islands occur naturally as wildfires burn across landscapes, and are important habitat refuges for species -- places where plants and animals survive the fire...

The project aimed to use existing models and data to understand how wildfires (number, size, and location) and land-use change will affect watersheds, and therefore water supply, under current conditions and future climates (through 2050) in the western U.S. The projected changes in temperature and precipitation are expected to affect water supply in two major ways: 1) decreased water availability, and 2) increased risk to watersheds via loses from fire. As the western population is projected to grow by 310 million people by 2100, this will potentially increase demand for diminishing supplies if housing growth occurs in rangelands or forested lands. Understanding watershed vulnerabilities due to changing climate,...

Aspen is an environmentally, economically, and socially important species in the western U.S. It is typically the most abundant deciduous tree species in mountainous landscapes of the western U.S., providing food and habitat for a variety of wildlife, including black bear, deer, elk, moose, and numerous bird species. Aspen woodlands also provide high quality forage for livestock and draw tourists to the region to view the golden vistas that form in the fall. However, aspen is currently declining across large portions of the West and it’s estimated that approximately 40% of western aspen will be without suitable climate conditions within 50 years. In the northern and central Rocky Mountains, it’s thought that reduced...

As the impacts of climate change amplify, understanding the consequences for wetlands will be critical for their sustainable management and conservation, particularly in arid regions such as the Columbia Plateau. The depressional wetlands in this region (wetlands located in topographic depressions where water can accumulate) are an important source of surface water during the summer months. However, their health depends directly on precipitation and evaporation, making them susceptible to changes in temperature and precipitation. Yet few tools for monitoring water movement patterns (hydrology) in and out of these landscapes currently exist, hindering efforts to model how they are changing. This project provided...

The distribution and abundance of cheatgrass, an invasive annual grass native to Eurasia, has increased substantially across the Intermountain West, including the Great Basin. Cheatgrass is highly flammable, and as it has expanded, the extent and frequency of fire in the Great Basin has increased by as much as 200%. These changes in fire regimes are associated with loss of the native sagebrush, grasses, and herbaceous flowering plants that provide habitat for many native animals, including Greater Sage-Grouse. Changes in vegetation and fire management have been suggested with the intent of conserving Greater Sage-Grouse. However, the potential responses of other sensitive-status birds to these changes in management...
