Forest Inventory Ground Plot Data And Interactive Map

The 'Data and Resources' box to the right includes a link to an FTP site where data, and a data dictionary, can be downloaded that provide access to compiled data from the primary ground-sampling programs managed by the Forest Analysis and Inventory Branch (FAIB) as well as a link to and Interactive Mapping App. FAIB ground-sampling programs include the Permanent Sample Plots (PSPs) that provide long term growth and yield information to support development and testing of growth-and-yield models. Active PSPs are the only plot type protected from harvesting. The Provincial Change Monitoring Inventory (CMI), Provincial Young Stand Monitoring (YSM) and National Forest Inventory (NFI) programs monitor the changes in growth, mortality, and forest health from statistically valid populations. Vegetation Resource Inventory (VRI) plots are used to audit and verify key spatial inventory attributes estimated during photo interpretation. The 'Ground Plot Data FTP' link contains tree- and plot-level compiled mensurational attributes for each ground plot across a series of repeated measurements. Both the PSP and non-PSP compilation outputs include a Data Dictionary that describes all the tables and attributes found in the downloadable files. The 'psp' dataset includes both inactive and active Permanent Sample Plot (PSP) data. The 'non-psp' dataset includes CMI, YSM, NFI, and VRI plots. The CMI, YSM and NFI plots are all located on a grid and only GENERALIZED COORDINATES are provided for these plot types. All PSP and VRI plots include REAL COORDINATES. The Interactive Mapping App provides a spatial view of FAIB ground plots with custom filters to enable selection of areas, BEC zones, species, TSA or plot types of interest. Once plots of interest are selected or filtered, an ‘export data’ button is available to download a plot summary file with limited attributes.
