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 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. Child Item 1: "Plant Functional Type Percent Cover Estimates from the Yukon Flats National Wildlife Refuge". Ocular percent cover estimates for eight plant functional types occurring in lake-margin wetland plant communities. Child Item 2: "Aboveground Net Primary Production Estimates from the Yukon Flats National Wildlife Refuge". The historical dynamics of the lake, the sampled community type, and the dry mass of annual new growth. Child Item 3: "Soil Properties of Lake-Margin Wetlands of the Yukon Flats National Wildlife Refuge". 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. Child Item 4: "Soil Microbial Data from the Yukon Flats National Wildlife Refuge 2009 to 2012". Soil properties and microbial data from lake-margin soils. Child Item 5: "Carbon and Nitrogen Content of Organic Soils in Lake-Margin Wetlands of the Yukon Flats National Wildlife Refuge". Soil core dimensions, bulk density, and carbon/nitrogen content of soil core samples within the organic soil horizon in lake-margin wetland plant communities. Child Item 6: "Total Carbon, Organic Carbon, and Nitrogen Data from a Subset of Soils Within the Yukon River Basin". Total and organic carbon values from soil samples taken from the Yukon River Basin.

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, Shrub, and Forest) for analyses. The dataset also includes a column indicating whether the adjacent lake had shrunk, fluctuated in size, or remained stable over time, as well as columns indicating the age in years of grass/sedge and shrub plant communities at that lake, defined as the number of years since the community type was last inundated by the lake, based on Landsat satellite imagery.
