Drought Streamflow Probabilities in Northeast Region

Maximum likelihood logistic regression (MLLR) is used to estimate drought probabilities for selected Northeast rivers and streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. This application allows the display and query of these drought streamflow probabilities for Northeastern streams.

Tree mortality in Sequoia National Park from 2004 to 2007 and during severe drought in 2014 to 2017

These data describe tree mortality and the factors associated with tree mortality for a variety of plots in Sequoia National Park. Most of the data were collected between 2014 and 2017 (during an extremely severe drought), along with some comparison data from 2004 to 2007. These data support the following publication: Stephenson, N.L., Das, A.J., Ampersee, N.J., Bulaon, B.M., and Yee, J.L.,

Early growth interactions between a mangrove and an herbaceous salt marsh species are not affected by elevated CO2 or drought, Louisiana saltmarsh, 2015

In recent decades the encroachment of woody mangrove species into herbaceous marshes has been documented along the U.S. northern Gulf of Mexico coast. These species shifts have been attributed primarily to rising sea levels and warming winter temperatures, but the role of elevated atmospheric carbon dioxide (CO2) and water availability may become more prominent drivers of species interactions unde

Long-term Experimental Forest Growth and Drought Data

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 c

Repeated drought alters resilience of seed bank regeneration in Taxodium distichum swamps of North America

Recurring drying and wetting events are likely to increase in frequency and intensity in predicted future droughts in the central United States and alter the regeneration potential of species. We explored the resistance of seed banks to successive droughts in 53 sites across the nine locations in baldcypress swamps in the southeastern United States. Along the Mississippi River Alluvial Valley and
