Drought is a natural hazard that inflicts costly damage to the environment and human communities. Although ample literature exists on the climatological aspects of drought, little is known on whether existing drought indices can predict the damages and how different human communities respond and adapt to the hazard. This project examines (1) whether existing drought indices can predict the occurrence of drought events and their actual damages; (2) how the adaptive capacity (i.e., resilience) varies across space; and (3) what public outreach and engagement effort would be most effective for mitigation of risk and impacts. The study region includes all 503 counties in Arkansas, Louisiana, New Mexico, Oklahoma, and...

A century of fire exclusion across many forest types in the western U.S. has resulted in unforeseen changes, including high fuel accumulations, high densities of trees, and increasing dominance of fire-intolerant species. These changes are particularly acute in forests that historically experienced high frequency and low severity fires. In response, the NPS Pacific-West region supports a large prescribed fire program to reduce understory fuels and forest density. Prescribed fire has been generally successful at reducing understory fuels and threats of catastrophic fire, and treated stands are expected to be more resistant to future wildfire. Less well understood is how well prescribed fire confers resistance to...
To address the data and information gap for characterizing coastal drought, a coastal salinity index (CSI) was developed using salinity data (Conrads 2016; Conrads and Darby, 2017). The CSI uses an approach similar to the Standardized Precipitation Index (SPI), a readily available drought index that is widely used for monitoring meteorological droughts (McKee and others, 1993). The CSI substitutes total monthly precipitation with monthly mean salinity data to determine the probability of recording a given salinity value in a particular month. The initial investigation demonstrated that the index could be used to delineate short- and long-term drought (saline) and wet (high freshwater inflow) conditions; however,...

It is well understood that plant phenology is sensitive to climate, however it is not so clear exactly how climate change might alter the spatial and temporal patterns of vegetation phenology. Satellite remote sensing offers a unique vantage point from which to observe phenological cycles across large regions. Although ubiquitous, cycles of green-up and brown-down are complex and exhibit great variability across space and time. Herbivore species such as elk, moose, and deer depend on the availability of herbaceous plants and deciduous shrubs for forage. These vegetation types are most nutritious for herbivores from early season to peak green-up, so characterizing vegetation cycles, or phenology, over the long term...

These data were compiled in order to represent long-term (multi-decadal) forest growth across eight different experimental forests in the United States, each with replicated levels of density treatments, as well as an important drought index correlated to growth. Forests around the world are experiencing severe droughts and elevated competitive intensity due to increased tree density. These data can be utilized to not only examine differences in within-stand competition, as well the trends and impact of drought in different forests across a broad climatic gradient, but also the influence of interactions between drought and competition on forest growth. Growth is measured as a treatment level, annual basal area increment...
EDDI is a drought indicator that uses atmospheric evaporative demand (E0) anomalies across a time-window of interest relative to its climatology to indicate the spatial extent and severity of drought. This page provides access to near-real-time (with a five-day latency, i.e., the most recent information is five days old) EDDI plots with time windows integrating E0 anomalies from 1 to 12 weeks and 1 to 12 months from the most current date. E0 is calculated using the Penman Monteith FAO56 reference evapotranspiration formulation driven by temperature, humidity, wind speed, and incoming solar radiation from the North American Land Data Assimilation System (NLDAS-2) dataset. For a particular time-window, EDDI is estimated...
The urgency for drought resilience planning has never been greater. With rapid changes in land use and increasing impacts from climate change, communities need to determine ways to meet their drought planning goals. Montana is forging new ground to join agencies, resource managers and communities to plan for drought impacts and build drought resilience. The State of Montana and the National Drought Resilience Partnership (NDRP)–a collaborative of federal and state agencies, non-governmental organizations (NGOs), and watershed stakeholders–are working together to leverage and deliver technical, human and financial resources to help address drought in the arid West.The Missouri Headwaters Basin in southwest Montana...
The South Central U.S. is one of the main agricultural regions in North America: annual agricultural production is valued at more than $44 billion dollars. However, as climate conditions change, the region is experiencing more frequent and severe droughts, with significant impacts on agriculture and broader consequences for land management. For example, in 2011 drought caused an estimated $7.6 billion in agricultural losses in Texas and an additional $1.6 billion in Oklahoma. Although there are many drought monitoring tools available, most of these tools were developed without input from the stakeholders, such as farmers and ranchers, who are intended to use them. The goal of this project is to assess the information...

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.
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...

Water is essential to our health, economy and quality of life. A scarcity of water has always characterized life in the West, and with increasing demands and limited supplies, smart and efficient water use is key. One answer is to develop conservation and drought mitigation strategies that start on the ground with full community participation and integrate high level tools available from state and federal partners.The National Drought Resiliency Partnership (NDRP) is a collaborative group of federal agencies working together to implement President Obama’s Climate Action Plan. In partnership with the Montana Department of Natural Resources and Conservation (DNRC) and other state and local collaborators, the Missouri...
