Southwest Alaska Network Ground Based Vegetation Monitoring 2007-2024 Survey Tabular Datasets

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 07, 2026 | Last Modified: 2025-08-05T00:00:00Z
SWAN_Vegetation_Database.zip contains 24 .csv's comprising the main components of the SWAN Vegetation Monitoring Database. SWAN_Vegetation_Database_Fields.zip contains another 24 .csv's describing the columns present on the main components of the SWAN Vegetation Monitoring Database along with another 10 .csv's describing categorical type data, where present. 8/5/2025 update: Includes a minor fix on taxon code around "FEBR2" (which was resolving to a date reference on Veg_Taxon and ~20 instances where "FEBR2" was encountered in field. Includes change of name "TreeSeedling" table (and related metadata) to "TreeSapling". Includes inclusion of 10 new categorical type metadata tables along with a few minor related changes to attribute tables (changing a few columns auto-identified as a "categorical" type to "character" type). Includes "one-line" descriptions of each of the 24 data tables present in Table and Relationships section of reference publish. Includes minor changes to "Plot" table (addition of two columns, Qualifier_Code and GRTS_Number) along with related changes to corresponding "Plot" attribute metadata and categorical metadata tables to describe added columns. Qualifier_Code and GRTS_Number are part of the concatenation that forms the "Plot" column referenced on most of the other data columns. Of note, catvars_SWAN_Veg_Plot.txt includes descriptions of the Qualifier_Code column, for which the "S" on "Plot" is derived from, when present. Depending on the park where the plot is present and the Elevation_Band_Code the plot is connected to, this "S" can either refer to "Spruce" (identified as a spruce forest sample, at either Elevation_Band_Code 1 or 2) or "South" (south of Turquoise Lake at LACL at Elevation_Band_Code 3). For more information, please refer to catvars_SWAN_Veg_Plot.txt contained in this reference or reference: "Protocol for Ground-based Monitoring of Vegetation in the Southwest Alaska Network" (https://irma.nps.gov/DataStore/Reference/Profile/2097701).
