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.
Healthy and functioning freshwater ecosystems are needed for successful conservation and management of native fish and invertebrate species, and the services they provide to communities across the U.S. Caribbean. Yet streams, rivers, and reservoirs are vulnerable to the effects of extreme weather, urbanization, energy development, and other environmental and human-caused disturbances. One major management concern is the impact of prolonged drought on freshwater ecosystems. Drought impacts streamflow, dissolved oxygen content, water quality, stream connectivity, habitat availability, and other characteristics necessary for sustaining fish and invertebrates. These changes can impact species interactions, abundance,...
Southern California relies heavily upon imported water from the Sacramento and Colorado river systems to augment local supplies and to mitigate the impacts of drought. In this paper a ‘perfect drought’ is defined as a prolonged drought that affects southern California, the Sacramento River basin and the upper Colorado River basin simultaneously. Examination of instrumental climate and discharge records shows that over the past century such perfect droughts do occur, but generally persist for less than five years. Perfect droughts that extend across all three areas are associated with anomalous upper-level high pressure off west coast and over western North America which is in turn associated with anomalously...
In response to recent severe drought conditions throughout the state, Arizona recently developed its first drought plan. The Governor's Drought Task Force focused on limiting the economic and social impacts of future droughts through enhanced adaptation and mitigation efforts. The plan was designed to maximize the use of new, scientific breakthroughs in climate monitoring and prediction and in vulnerability assessment. The long term objective of the monitoring system is to allow for evaluation of conditions in multiple sectors and at multiple scales. Stakeholder engagement and decision support are key objectives in reducing Arizona's vulnerability in light of the potential for severe, sustained drought. The drivers...

Abstract (from AGU100): Forest conservation and carbon sequestration efforts are on the rise, yet the long‐term stability of these efforts under a changing climate remains unknown. We generate nearly three decades of remotely sensed canopy water content throughout California, which we use to determine patterns of drought stress. Linking these patterns of drought stress with meteorological variables enables us to quantify spatially explicit biophysical drought resistance in terms of magnitude and duration. These maps reveal significant spatial heterogeneity in drought resistance and demonstrate that almost all forests have less resistance to severe, persistent droughts. By identifying the spatial patterning of biophysical...
New tree-ring records of ring-width from remnant preserved wood are analyzed to extend the record of reconstructed annual flows of the Colorado River at Lee Ferry into the Medieval Climate Anomaly, when epic droughts are hypothesized from other paleoclimatic evidence to have affected various parts of western North America. The most extreme low-frequency feature of the new reconstruction, covering A. D. 762-2005, is a hydrologic drought in the mid-1100s. The drought is characterized by a decrease of more than 15% in mean annual flow averaged over 25 years, and by the absence of high annual flows over a longer period of about six decades. The drought is consistent in timing with dry conditions inferred from tree-ring...
THE RISING RISK OF DROUGHT. Droughts of the twenty-first century are characterized by hotter temperatures, longer duration, and greater spatial extent, and are increasingly exacerbated by human demands for water. This situation increases the vulnerability of ecosystems to drought, including a rise in drought-driven tree mortality globally (Allen et al. 2015) and anticipated ecosystem transformations from one state to another—for example, forest to a shrubland (Jiang et al. 2013). When a drought drives changes within ecosystems, there can be a ripple effect through human communities that depend on those ecosystems for critical goods and services (Millar and Stephenson 2015). For example, the “Millennium Drought”...

Climate change impacts on water resources in the Pacific Northwest are predicted to have transformational effects on agriculture. Loss of winter snow pack, reduced summer stream flows, and increased summer temperatures are all phenomena that have already been observed, and are expected to worsen over this century. Research is ongoing in the Northwest to understand agriculture practices that might allow farmers to prepare for these climate change impacts. One potential technique is the use of biochars (charcoal made from decomposition of organic matter at high temperatures in the absence of oxygen), which can be used as a soil amendment that can increase soil moisture retention, improve agricultural yields, and hold...
During droughts, localized areas of the landscape (drought refugia) retain surface water and soil moisture needed to sustain wildlife and vegetation. Remote sensing from satellite imagery offers powerful tools to identify refugia and study their responses to changing weather patterns over time. This talk will present two recent applications of remote-sensing analysis related to drought refugia research in southern Oregon. In one study, hydrologic resilience of springs was inferred using remote sensing of groundwater-dependent vegetation in a semi-arid sage steppe ecosystem. In another, refugia from drought and mountain pine beetle were identified in lodgepole pine and whitebark pine forest. Efforts are currently...
A critical aspects of the uniqueness of coastal drought is the effects on salinity dynamics of creeks and rivers. The location of the freshwater-saltwater interface along the coast is an important factor in the ecological and socio-economic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including streamflow, precipitation, sea level, tidal cycles, winds, and tropical storms. The position of the interface determines the composition of freshwater and saltwater aquatic communities as well as the freshwater availability for water intakes. Many definitions of drought have been proposed, with most describing a decline in precipitation which has...
Ongoing drought in the Colorado River Basin, unprecedented urban growth in the watershed, and numerical model simulations showing higher temperatures and lower precipitation totals in the future have all combined to heighten interest in drought in this region. In this investigation, we use principal components analysis (PCA) to independently assess the influence of various teleconnections on Basin-wide and sub-regional winter season Palmer Hydrological Drought Index (PHDI) and precipitation variations in the Basin. We find that the Pacific Decadal Oscillation (PDO) explains more variance in PHDI than El Nio-Southern Oscillation (ENSO), the Atlantic Multidecadal Oscillation (AMO), and the planetary temperature combined...

Forests in the U.S. Caribbean are spectacularly diverse, with more than 500 native tree species in Puerto Rico alone. These forests and trees provide many services to the region's 3.5 million people, including watershed and coastal protection, economic benefits from fruit and wood, cooling in urban environments, and improved water quality, recreation, habitat, and biodiversity protection. Caribbean forests range from coastal mangroves and dry forests, to rainy cloud forests on the mountain peaks. They have been shaped by frequent natural disturbances such as hurricanes, drought, flooding, landslides, and wildfire. Projected increases in temperatures and reduced or greater variability in rainfall may lead to increased...

In the Pacific Northwest, coastal ecosystems are highly productive areas that support millions of migratory waterbirds, shellfish, salmon and related fish. 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...
