Riparian systems are critical to the human and ecological communities that interact with them. For the members of San Carlos Apache Tribe, this is particularly true, as riparian systems provide immense cultural and natural values such as ceremonial grounds and recreation areas. However, the riparian areas within the San Carlos Apache Reservation are at risk of degradation due to climate change and land use. Over the past several decades, invasive vegetation, changes in river discharge, and increased wildfire activity have continued to threaten the area’s riparian resources. This project aims to inform riparian restoration efforts by providing products that: identify historic vegetation and river channel properties,...

As the climate continues to change, vulnerable wildlife species will need specific management strategies to help them adapt to these changes. One specific management strategy is based on the idea that some locations that species inhabit today will remain suitable over time and should be protected. The climate conditions at those locations will continue to be good enough for species to survive and breed successfully and are referred to as climate refugia. Another management strategy is based on the idea that species will need to shift across the landscape to track suitable conditions and reach climate refugia locations as climate and land uses change over time. The more opportunities we can give species to safely...

While 21st century temperatures are projected to increase in Puerto Rico and the broader U.S. Caribbean (whose geography is contained within the Caribbean Landscape Conservation Cooperative, or CLCC), the low variability and already high annual average temperatures suggest that the largest climate-related impact on ecosystems and water resources is more likely to be through changes in the timing, pattern, and availability of moisture. The development of adaptation strategies that respond to anthropogenic climate change for the CLCC, and particularly for Puerto Rico, is currently hindered by the lack of local-scale climate scenarios that resolve the complex topographical and meso-scale climate features that will...

Salmon that spawn and rear in Southeast Alaska watersheds are critically important to the region’s economic vitality and cultural identity. An estimated 90% of rural households in Southeast Alaska use salmon. Environmental changes that compromise the ability of these streams to support salmon could have dramatic consequences for the region. In particular, there is concern that climate change could undermine the capacity of the region’s streams to support productive fisheries. As a result, regional stakeholders are interested in identifying some of the potential impacts of climate change on watersheds that support abundant salmon. These stakeholders include federal and state agencies (U.S. Fish and Wildlife Service,...

This project generated a series of freely available datasets that provide projections of climate change at appropriate spatial scales that can directly address specific management questions. These climate change projections are the result of “downscaling” output from global climate models (GCMs) that formed the basis of many conclusions in the Intergovernmental Panel on Climate Change (IPCC) Assessment Report 5 (AR5). The datasets include projections of climate variables in addition to daily temperature and precipitation such as surface winds, humidity, and solar radiation that are needed in hydrologic and ecological modeling. Two products, one at a 4-km resolution and the other at a 6-km resolution, covering the...

Snow conditions are changing dramatically in the mountains of the interior Pacific Northwest, including eastern Washington, northern Idaho, and western Montana. These changes can both benefit and hinder a variety of wildlife species. The timing and extent of seasonal snowpacks, in addition to snow depth, density, and hardness, can impact the ability of wildlife to access forage, their ability to move across the landscape, and their vulnerability to predators, to name a few. In order to respond effectively to changes in snow conditions, wildlife managers need tools to identify areas and promote conditions that maintain late spring and early summer snowpack for some sensitive species. Managers also require an index...

Science produced by the National and Regional Climate Adaptation Science Center (CASC) network must ideally be scientifically sound, relevant to a management decision, fair and respectful of stakeholders’ divergent values, and produced through a process of iterative collaboration between scientists and managers. However, research that aims to produce usable knowledge and collaborative approaches that boost usability are not common in academia or federal research programs. As a result, neither the process of creating such research nor the impacts to stakeholders are well understood or well documented. This lack of attention to the processes and impacts of collaborative scientist-stakeholder knowledge production also...

Forested areas in the Western U.S. that are impacted by disturbances such as fire and drought have increased in recent decades. This trend is likely to continue, with the increase in frequency and extent of wildfire activity being especially concerning. Resource managers need reliable scientific information to better understand wildfire occurrence, which can vary substantially across landscapes and throughout time. However, few scientific models capture this variability, and projections of future potential changes in fire occurrence can include some uncertainty. This uncertainty can limit our ability to anticipate potential wildfire impacts on society and ecological systems. Another method to help managers prepare...

There are significant investments by states and resource agencies in the northeast U.S. for invasive aquatic species monitoring and management. These investments in jurisdictional waters help maintain their use for drinking, industry, and recreation. It is essential to understand the risks from invasive species, because once established, species can be costly to society and difficult or impossible to control. Identifying which species are most likely to move into a new region and cause harmful impacts can aid in preventing introductions and establishment. This is especially important in response to climate change as habitats potentially become usable to previously range-restricted species. Currently, hundreds...

A change in wildfire regimes and the expansion of invasive grasses are degrading sagebrush ecosystems, altering wildlife habitats, and threatening property and human livelihoods. In response, land managers often treat large areas of land with fuel reduction or post-fire seeding treatments in an attempt to reduce these risks. However, the trajectories of ecosystem change following treatment are inconsistent across the sagebrush steppe. In some places, treatments are successful, leading to a decrease in invasive grasses which allows native plants to recover. In other places, treatments either have no effect or they facilitate the spread of invasive grasses. Under some climate conditions, native grasses and forbs do...
