In the Northwest U.S., warming temperatures and changing precipitation patterns will likely result in significantly altered snowpack, stream flows, and water availability. Along with these changes comes an increased risk of “ecological drought”, or periods of water stress that impact ecosystems and the services they provide –which can ultimately impact human communities. More frequent and severe ecological droughts have the potential to push ecosystems beyond their ability to recover, resulting in complete changes in ecosystem composition and function. Ecological drought will only worsen existing management challenges, such as competition for water resources, habitat degradation, invasive species, and more frequent...

Severe droughts cause widespread tree mortality and decreased growth in forests across the globe—even in areas with cooler climates. Mitigating the negative effects of climate change, in particular increased drought frequency and severity, poses a major challenge to forest managers. Managers are searching for strategies that minimize the negative effects of drought on forests (i.e. increase their resistance to drought) and maximize the ability of forests to recover after a drought (i.e. improve their resilience). Evidence suggests that forests with certain combinations of tree species, sizes, and stem densities are better able to withstand and recover from drought. The goal of this study was to identify which...

Drought poses a major threat to New Mexico’s state fish, the Rio Grande cutthroat trout. This southernmost subspecies of cutthroat trout, found only in New Mexico and Colorado, has already been restricted to an estimated 12% of its former range. Now climate change, in the form of lower winter snowpack and reduced precipitation, challenges its long-term persistence. This trout tends to occupy small and fragmented streams, which are at higher risk of drying up during drought events. Yet, the full extent of drought impacts to Rio Grande cutthroat trout is unknown. To address this knowledge gap, researchers examined the effects of drought - in particular stream intermittency - on the growth and survival of Rio Grande...

Warmer temperatures and less precipitation in the western U.S. related to climate change are harming many important natural resources, including forests, rivers, and many fish and wildlife species. Climate refugia provide a potential opportunity for conserving resources and biodiversity in the face of climate change. These refugia are places where the climate will likely change less than the surrounding landscape and/or places in a landscape where species may move to find more suitable climates. For example, because climate change may alter the frequency, duration, or severity of droughts, small habitats that naturally retain water (drought refugia) may become increasingly important to many natural wildlife communities....

California’s Central Valley is a nexus for water resources in the state, draining the Sacramento and San Joaquin River watersheds. Urban centers, agricultural operations, and the environment all compete for limited water, and demand is expected to only increase as the population grows and agriculture intensifies. At the same time, the water supply is projected to decrease as temperatures rise, precipitation patterns change, and the frequency of extreme droughts increases. The Central Valley also provides critical wetland habitats to migratory waterbirds, and wetland managers require information on how to best use water resources to support wildlife objectives, particularly during drought. This project seeks to...

In 2017, California was experiencing its most severe drought in over a millennia. Low rainfall and record high temperatures resulted in increased tree mortality and complete forest diebacks across the West. Though land managers scrambled to respond, they lacked information needed to make informed decisions. Focusing on California’s central and southern Sierra Nevada Mountains, this project seeks to determine whether a key forest management practice – forest thinning via prescribed fire – can help forests better survive drought. Prescribed fire is commonly used in the western U.S. to remove potential wildfire fuel, such as small trees and shrubs. It is also thought that this act of selectively removing trees helps...

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...

The Missouri River system is the life-blood of the American Midwest, providing critical water resources that drive the region’s agriculture, industry, hydroelectric power generation, and ecosystems. The basin has a long history of development and diversion of water resources, meaning that streamflow records that reflect natural, unmanaged flows over the past century have been rare. As a result, research on the complex interactions between temperature and precipitation in driving droughts and surface water variability in the Missouri River Basin has lagged behind similar work done in other major basins in the country, and has hindered drought planning efforts. To address this need, researchers will use tree-rings...

The White House Council for Environmental Quality has identified two national watersheds to pilot large-scale drought resiliency implementation. The Missouri Headwaters Basin within the GNLCC region and High Divide landscape is one of these national demonstration areas, and the GNLCC can advance its collective mission with this opportunity. By delivering science to management and building a learning network among watershed groups, this project will align the large-scale watershed management efforts of the GNLCC with the National Drought Resiliency Program (NDRP) and the Montana Department of Natural Resources (DNRC) to build drought resilience into this important northern Rocky Mountain landscape.FY2015and FY2016The...

The need to improve fire weather predictions for the southern Great Plains has grown in recent years, following a number of extreme fire events. While on-the-ground conditions that promote fire development in the region are still not well understood, research suggests that fire-friendly conditions are determined by more than just precipitation amounts or wind speeds. They are also influenced by soil characteristics such as moisture content, temperature, and human use. Therefore, fire weather forecast predictions could be improved by developing a better understanding of the relationship between soil characteristics and fire occurrence. With a hotter and drier future unfolding in the southern Great Plains, the time...

During the severe drought of 2010-2015, several communities in southeast Oklahoma almost ran out of water. Some of these communities rely on streams and rivers as their sole source of water and when these sources almost ran dry, it left them searching for alternatives and wondering how to continue growing, economically, with this water uncertainty. The possibility of climate change has these communities further concerned, primarily because they do not know what to expect. Previously, the USGS, both Chickasaw and Choctaw Nations collaborated on a project to apply a range of possible climate change scenarios to the Red River watershed to determine future water availability. This study will focus specifically on southeast...

Streams are classified as perennial (flowing uninterrupted, year-round) or intermittent (flowing part of the year) or ephemeral (flowing only during rainfall events). The classifications of “streamflow permanence” were primarily established in the middle 20th century and are often outdated and inaccurate today if they were not adjusted for changes in land use, wildfires, or climate.Understanding where streams are perennial is important for a variety of reasons. For example, perennial streams receive special regulatory protections under a variety of statutes, and provide important habitat for fish, wildlife, and other species. To predict the likelihood that streams are perennial, we compiled nearly 25,000 observations...

Migratory birds may be hit especially hard by climate change – particularly waterbirds that depend on wetlands as resting and feeding sites during their journey between breeding and non-breeding grounds. California’s Central Valley and the interior basins of southeastern Oregon and northeastern California provide some of the most critical wetlands resources to migratory waterbirds in the western U.S. However, these wetlands rely heavily on snow pack and precipitation for water supply, both of which have already decreased due to climate change. Of further concern is the fact that drought conditions resulting from climate change could exacerbate existing water allocation issues in the region. Researchers are examining...

Over the past century, Hawaiʻi has experienced a pronounced decline in precipitation and stream flow and a number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. Several climate-related factors are influencing Hawaiˈi’s landscapes and contributing to these changes. These include climate change, climate variability, and drought (referred to collectively as CCVD). Climate variability describes how the climate fluctuates on a yearly basis around average values, while climate change describes patterns of long-term continuous change in the average. While it is understood that CCVD...

In the Northeastern U.S., climate change is expected to increase the frequency of extreme precipitation events. However, less rain is predicted to fall in between these extreme events and air temperatures are also expected to rise. This combination of conditions will likely expose the Northeast to both floods and droughts that will have significant ecological, social, and economic implications for the region. Infrastructure damage from extreme storm events, increased competition for water supplies during droughts, and the potential loss of wildlife and habitats are some of the various challenges facing resource managers and decision makers. Management actions that mitigate the damage from extreme floods and droughts...

Due to the ecological importance of stream temperature for aquatic species, and concern about rising temperatures associated with climate change, natural resource managers throughout the Pacific Northwest increasingly require locally detailed stream temperature information in order to effectively manage aquatic resources. Recent technological advances in stream temperature monitoring (e.g., digital data loggers and remote sensors) and modeling have increased the amount of data that are available (both observed and projected) throughout the region. These newly available data, although exciting, have strengths and limitations depending on the purposes for which they were developed and the scale(s) at which they can...
