This is a child item of the USGS Data Release: https://doi.org/10.5066/P9QF8RR5 This dataset is a single comma-delimited text file (.csv). Data include the name of lakes where samples were obtained, the historical dynamics of that lake, the sampled community type, and the dry mass of annual new growth. Shrub community measurements are a combination of understory mass from quadrat harvests and shrub stem mass derived from published allometric equations.
This is a child item of the USGS Data Release: https://doi.org/10.5066/P9QF8RR5 This dataset is a single comma-delimited text file (.csv). Data include the name of lakes where samples were obtained, soil pH, electrical conductivity (EC), water content (VWC), and bulk density (BD) of soil core samples within organic soil horizon in lake-margin wetland plant communities.
This is a child item of the USGS Data Release: https://doi.org/10.5066/P9QF8RR5 Total and organic carbon values from soil samples taken from the Yukon River Basin, Alaska. These samples were used to create a relationship between total carbon and organic carbon for samples which were only run for total carbon.

Yukon Flats National Wildlife Refuge
This data release includes six child items of soil and vegetation data from lake margin soils of the Yukon Flats National Wildlife Refuge, Alaska. Data includes multiple lakes that are defined as either stable or drying. Lake margin vegetation communities include graminoid, shrub, and forest. Sols are separated into organic and mineral layers. Microbial data includes different phospholipid fatty acids and soil enzyme activity data for multiple enzymes involved in C,N, and P cycling. Data also includes information on respiration rate constants (k) and labile substrate pool (Ao) from soil incubations. Other soil chemical attributes such as soil pH, electrical conductivity, percent C and percent N are also included....
This is a child item of the USGS Data Release: https://doi.org/10.5066/P9QF8RR5 This dataset includes soil properties and microbial data from lake margin soils throughout the Yukon Flats National Wildlife Refuge. Data include multiple lakes that are defined as either stable or drying. Lake margin vegetation communities include graminoid, shrub, and forest. Sols are separated into organic and mineral layers. Microbial data includes different phospholipid fatty acids and soil enzyme activity data for multiple enzymes involved in C,N, and P cycling. Data also includes information on respiration rate constants (k) and labile substrate pool (Ao) from soil incubations.
This is a child item of the USGS Data Release: https://doi.org/10.5066/P9QF8RR5 The file contains ocular percent cover estimates for eight plant functional types occurring in lake-margin wetland plant communities in the Yukon River floodplain within the Yukon Flats National Wildlife Refuge. Observations were collected along up to four 100-meter linear transects oriented perpendicular to the lakeshore. Eight cover classes were used, and the median % cover for each cover class is shown in the dataset. Separate percent cover observations were recorded for each of eight distinct plant community encountered along each transect. Community types were associated with one of three aggregate community types (Grass/Sedge,...

This data package includes 481 geospatial vector polygons of historic fire perimeters associated with National Wildlife Refuges in Alaska. These polygons, originally held within the Alaska Large Fire Database (ALFD), were reviewed and found to have geospatial inaccuracies with respect to the fire they represent. They were corrected and updated based on a variety of remote sensing resources; the Monitoring Trends in Burn Severity (MTBS) database (https://www.mtbs.gov/viewer/index.html), geospatial rasters of historic fire activity derived from Landsat 1-9 imagery in the Google Earth Engine(https://earthengine.google.com) environment, and historical air photos acquired through EarthExplorer (https://earthexplorer.usgs.gov/)....
