Tracking Forest and Hydrological Resilience to Compound Stressors in Burned Forests Under a Changing Climate In the Northern Rockies, the annual area burned by wildfires has risen sharply in recent decades and is expected to continue growing. As a result, burned forests increasingly comprise a significant portion of the land base. However, burned areas represent a difficult paradox for land managers, especially in the context of other climate-linked disturbances (e.g., droughts, bark beetle outbreaks) that are also on the rise and may compound initial fire-induced stressors. While, burned areas have experienced major recent changes that may decrease their resilience to subsequent, compounding stressors, fire-induced changes can also lead to longer-term increases in resilience. The evolving landscape conditions triggered...

According to previous studies, temperatures are expected to continue to rise throughout the southern states, and droughts are predicted to be longer and more severe. Even small changes to a river’s water flow regime may have unanticipated consequences on the water resources, especially for communities that rely on direct river diversions to supply their needs. A suitable water availability model is a key tool needed to help communities investigate where vulnerabilities in water resources may occur and the...

The capture and reuse of wastewater is a promising strategy for increasing available water, but the costs and benefits of wastewater reuse are poorly quantified. In many locations, wastewater forms a significant component of stream flows for downstream beneficial uses. While wastewater reuse can boost local water availability, it also may reduce downstream flows and have negative impacts on downstream ecosystems. Therefore, assessing...

The concern is that current management strategies that focus exclusively on single invasive species and overlook climate-driven biological interactions, may lead to poor decisions. By delivering actionable science, this project directly informs specific planning, management and decision needs of tribal and governmental partners working in the Columbia River Basin. First, we assess the information needs for, and barriers to, effective aquatic invasive species management in the face of climate change in the Columbia River Basin. This helps synthesize knowledge and build...

Snow cover helps regulate the earth’s temperature and stores water on the landscape. As it melts, snow hydrates the soil and replenishes the freshwater supplies of streams and lakes, providing water for vegetation, wildlife, and human activities such as agriculture and electricity generation. Understanding present and future snow conditions under climate change is critical for managing Alaska’s natural resources, yet many scientists, land managers, and policymakers lack this information at useful scales. Hence, the goal of this project was to produce an advanced snow modeling system for part of the Arctic that predicts a variety of factors...

The quantity of water flowing into the northern section of the river depends on how much snowpack from the Rocky Mountains melts into runoff and on seasonal precipitation rates. Models describing the relationship between winter snowpack quantity and springtime snowmelt runoff quantities for the basin are combined with models describing long-term natural variation in precipitation to create water supply outlooks. The outlooks developed by the U.S. Natural Resources Conservation Service are currently used by stakeholders to make critical water allocation decisions in the basin. Improvements...

Mountain forests are a critical part of the hydrologic cycle that feeds these rivers, providing water supply and storage. However wildfire, which is becoming more common as temperatures rise, can disrupt the role of mountain forests in the hydrologic cycle. Uncertainty about the interactions between wildfire and snow-water, and how these interactions may change as climate conditions shift, impedes effective water resource planning...

Unfortunately, harmful algal blooms are becoming more common in these waters, causing health issues for humans and animals. While it is clear that nutrients stimulate algae growth, it isn’t clear if there are other parameters that stimulate the development of harmful algal blooms. The scientific literature describes additional parameters that may affect algae growth, such as storm occurrence, temperature, dissolved metals, erosion of soils, length of growing season, and hydroperiod.This project will address these different parameters and examine how climate...

Once it reaches the ground, rain can either run off and contribute to water flow in streams, or it can infiltrate into the ground and provide water for plants and recharge aquifers and groundwater. The exact route that water takes is controlled by many factors, including the duration and intensity of rainfall, the topography of the land, soil properties, and vegetation. The introduction and spread of invasive plants and animals in Hawaiian forests, which alters the water-use and soil characteristics of ecosystems, can have large impacts on downstream water users. Increased demand and competition for limited... Categories: Project; Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service; Tags: 2016, CASC, Completed, Forests, Landscapes, All tags...

Pacific salmon need cold water and quality habitat to survive. As climate change continues to increase river temperatures, effective methods to restore cool-water refuges and logjam habitats need to be determined. Many salmon habitat restoration projects in the Pacific Northwest have built engineered logjams (ELJs) to create deep, cool pools and reconnect rivers to floodplains to replenish cool groundwater. However, the success of these projects is not often studied. This project will study restoration effectiveness in helping salmon adapt to climate change so that this once-abundant resource can continue to enrich the local culture, economy, and environment.

Invasive plants harm water quality, occupy habitat for native species, reduce recreation opportunities, and damage infrastructure such as pumps and dams. Resource managers from federal, state, and local agencies, as well as local non-profits, spend hundreds of thousands of dollars on monitoring and exterminating invasive plants. Management costs and damages are likely to rise as climate change warms temperatures and reduces rainfall across the basin, expanding potential habitat for invasive plants and affecting the effectiveness of management.

These species depend on food and habitats provided by estuaries (coastal tidal areas where streams and rivers flow into the ocean) for successful migration and breeding. Climate change effects such as drought, sea-level rise, and changing freshwater flow, precipitation, and temperatures will alter these important habitats. This study examined how changing ocean and freshwater patterns and conditions will influence estuary habitats. The main goal was to provide scientific support for future planning efforts and conservation of natural resources found in coastal...

Water moving through these aquifers carves out magnificent caves, sinkholes, and other formations. These formations are home to high concentrations of rare and endangered species, but the hydrological conditions that support these species can change rapidly. Managing these ecosystems into the future requires a better understanding of how climate, hydrology, and karst ecosystems interact. The objective of this project was to determine how species and ecosystems associated with karst might respond to future temperature and precipitation extremes and accompanying changes in groundwater levels and...

The complex mountain and valley chains of the Southwest exert a strong influence on precipitation and wind patterns. Atmospheric rivers deliver some of the most extreme precipitation events to west-southwest-facing slopes of the mountains where strong gusty downslope winds can also spread wildfires. Climate change is making the southwest warmer and dryer resulting in more fire-prone vegetation and more frequent and extreme atmospheric rivers. Understanding this changing system is critical for managing water resources and wildfire in the region. This project will study how climate change is impacting precipitation and winds to create fire weather and drive fire spread on heavily vegetated slopes of coastal mountains....

In Alaska, snow avalanches are the deadliest natural hazard, and they affect a large portion of the state, significantly impacting the natural landscape, the built environment, and public safety. As climate warming continues, it is expected that Alaska’s vulnerability to avalanche hazards will also continue to increase. Currently, there is limited public awareness and available information to support adaptation, mitigation and preparedness efforts for these hazards.

Changes in snow are also economically important to many sectors, from recreation to commercial fishing. An earlier set of rain-snow partitioning and snowfall equivalent projections based on downscaled CMIP3 temperature and precipitation projections have been used extensively. In this project, we developed updated projections for the fraction of precipitation days that are snowy (vs. rainy) and the amount of precipitation that likely falls as snow to be consistent with the newest downscaled temperature and precipitation released by SNAP. The outputs are decadal monthly averages. The updated snow...

Salt marsh has been identified as an essential fish and wildlife habitat, and loss of saltmarsh corresponds with precipitous declines in marsh-dependent wildlife. For example, the global population of Saltmarsh Sparrow is predicted to collapse within the next 50 years after experiencing a 9% annual decline across the northeastern U.S. Resource managers require tools to help restore salt marsh habitat for wildlife by adapting marshes to climate change-driven sea level rise. However, adaptation approaches need to be tested and evaluated before widespread application. Researchers are testing a rapidly emerging sea...

Not only has this translated into a longer fire season, but reduced snowpack has cascading effects that impact streamflow, water supplies, agricultural productivity, and ecosystems. California receives 80% of its precipitation during the winter, so mountain snowpack plays a critical role in replenishing the state’s water supply. One factor that affects the amount of winter precipitation (and therefore snowpack) in California is the North Pacific Jet (NPJ)—a current of strong, high altitude winds that occur over the northern Pacific Ocean. Winters when the NPJ is located further north than normal are drier than...
