Pre-fire biomass, burn severity, biomass consumption, and fire perimeter data for the 1987 Black Dragon Fire in China Pre-fire biomass, burn severity, biomass consumption, and fire perimeter data for the 1987 Black Dragon Fire in China
Geospatial data were developed to characterize pre-fire biomass, burn severity, and biomass consumed for the Black Dragon Fire that burned in northern China in 1987. Pre-fire aboveground tree biomass (Mh/ha) raster data were derived by relating plot-level forest inventory data with pre-fire Landsat imagery from 1986 and 1987. Biomass data were generated for individual species: Dahurian...
Habitat Structure Maps for the California Central Valley 2013-2017 Habitat Structure Maps for the California Central Valley 2013-2017
We produced a time series of maps of habitat structure within wetlands of the Central Valley of California. The structure of open water and tall emergent vegetation, such as Typha spp. and Schoenoplectus spp., is critical for migratory birds. Through field observation and digitization of high resolution imagery we identified the locations of tall emergent vegetation, water, and other...
A comprehensive inventory of perennial snow and ice in Glacier National Park in 2005 A comprehensive inventory of perennial snow and ice in Glacier National Park in 2005
These polygon features represent a comprehensive inventory of perennial snow and ice on the landscape in Glacier National Park (GNP) in 2005. The imagery used to delineate perennial snow and ice was taken late season, therefore, all snow and ice present on the landscape is assumed to be perennial. Whether each polygon is "perennial snow and ice" or "active glacial ice" is included...
Kentucky Drought Condition Monitor Kentucky Drought Condition Monitor
The Ohio-Kentucky-Indiana WSC/Kentucky Agricultural Development Board choose four parameters to monitor drought: precipitation, streamflow, groundwater level, and crop moisture index. These parameters are frequently used by the Kentucky Drought Mitigation and Response Plan (2008) as indicators of the four stages of drought: drought advisory, moderate drought, severe drought, and extreme...
Estimated daily mean streamflows for HUC12 pour points in the southeastern United States, 1950-2009 Estimated daily mean streamflows for HUC12 pour points in the southeastern United States, 1950-2009
This data release contains estimated daily streamflow values for 9,203 12-digit hydrologic unit codes (HUC12s) in the southeastern United States for the period 1950-2009. The files are provided in text format, which can be used in R and in other programs. The 'Site Info' folder contains 18 files with streamgage information and the 'Daily Values' folder contains 18 files with predicted...
Detection of invasive aquatic plants Myriophyllum spicatum and Egeria densa in lakes using eDNA, field and mesocosm data Detection of invasive aquatic plants Myriophyllum spicatum and Egeria densa in lakes using eDNA, field and mesocosm data
We conducted a study to test the factors related to detectability of two invasive aquatic plants (Egeria densa and Myriophyllym spicatum) using environmental DNA (eDNA), over extended periods of time, and specifically examined how plant growth stage and abundance relates to eDNA detection in semi-natural and natural conditions. This dataset is from sampling performed in summer of 2018 in...
