This table contains data on the growing stock volume on forest land and on poorly productive forest land on mineral soils and peatlands, categorized by tree species. The data is sourced from 'Luke' website, which originates from Finland (ISO country code: 'fi'). The table consists of columns such as '_extract_date', '_row_number', 'inventory', 'region', 'principal_site_class_group', 'tree_species', and 'growing_stock_volume_on_forest_land_and_on_poorly_productive_forest_land_on_mineral_soils_and_peatlands_by_tree_species' which provide information about the date of extraction, row number, inventory details, region, principal site class group, tree species, and the growing stock volume. This data can be analyzed to study the distribution and volume of growing stock across different regions, track changes in growing stock over time, analyze the impact of site class on stock volume, and compare the stock volume of different tree species.
