Science Tools for Managers

Ensuring the long-term sustainability of water resources requires careful stewardship of water for societal uses (i.e. municipal, agricultural, and industrial sectors) and also for the many other benefits that aquatic ecosystems provide to humans. In particular, reservoir fisheries and river ecosystems provide a range of economic, cultural, and recreational benefits. Maximizing the benefits that w

Water temperatures affect the distribution, growth potential, and productivity of stream fishes that are targeted in subsistence, sport, and commercial fisheries across Alaska, making stream and lake temperature data critical for managing freshwater resources. Evaluating the variation in temperatures across Alaska will improve understanding of impacts of both climate change and development on fres

The complex challenge of adapting to climate changerequires collaborative solutions that can be enhanced by connecting individuals to each other and to essential information. This project will evaluate the effectiveness of online decision information tools designed to aid adaptation, that are supported by the development of a network of practice. Networks can aid adaptation by improving the quanti

This project seeks to enhance the stewardship of historic buildings vulnerable to climate change impacts. As sea level rise and storm-related flooding and erosion threaten our nation’s cultural heritage, there is a critical need to ensure that climate change adaptation decisions, including what cultural resources will be “let go”, are transparent and informed by the opinion of people whose heritag

Future climate conditions may dramatically impact many of the natural resources, cultural resources, and ecosystem services on which society depends. To ensure the long-term sustainability of these resources, decision-makers across many domains (e.g. federal, state, NGO, Tribal) commonly consider climate forecasts in their strategic planning efforts. In the South Central United States, future clim

Freshwater is a critical driver for island ecosystems and essential part of the water cycle in tropical islands, which is threaten by climate change. Changes in streamflow patterns may impact streams, estuarine, and coastal habitats. In Hawai‘i, these habitats support five native stream fish species. To examine how changes in streamflow have impacted habitat quality for these native aquatic speci

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

The greater Mississippi River Basin (MRB) is the largest river basin in North America and the fourth largest basin in the world. The MRB encompasses 24 terrestrial ecosystems, providing habitat for 100 species of mammals, reptiles, and amphibians Its floodplain supports 40% of the waterfowl and wading birds in North America, and the MRB’s rivers transport 40% of the nation’s total exports. Dozens

As climate change is impacting water resources and aquatic ecosystems, there is a great need for natural resource managers to assess adaptation measures in a holistic manner. This can be done by integrating model predictions of climate, hydrology, and ecosystems with observational data to better refine estimates of conditions on-the-ground; however, it can be challenging to combine these different

Stream flow is directly tied to climate, and numerous studies provide substantial evidence that climate change is a threat to future aquatic water flow processes. In the southwestern United States, mountain snow is a primary water source for streams and rivers. However, climate change is threatening the region's mountain snow, leading to reduced snowpack, earlier snowmelt, and more precipitation f

Rain-on-snow events occur when warm rain falls on an existing snowpack, causing rapid snowmelt that can lead to damaging floods, reduced spring and summer streamflow, and altered stream temperatures, with ecological, social, and economic consequences. Rain-on-snow events can result in a loss of riverine biodiversity, decreases in fisheries production, and degradation of stream habitat; water short

Coastal ecosystems are uniquely vulnerable to changes in the quantity and quality of freshwater discharge. With a warming climate, changes in freshwater discharge into estuaries will interact with rising sea levels. Coastal natural resource managers need guidance on the potential impacts and vulnerabilities to better manage the risks to aquatic species and habitats and to mitigate species decline
