Table 6 Harmonized tree species categories and summary statistics for differences in forest areas between Daubrée statistics (1908) and national forest inventory data (20081) across NUTS-3 units, Forests area differences according department administrative units (NUTS-3) population were calculated over the 1908–2008 period. Significance of the forest area differences were analyzed using a paired t test. Tree species not specified in oak, various broadleaves, and various conifers, yet deduced for the oak group (see Annex 4)

From: Ancient forest statistics provide centennial perspective over the status and dynamics of forest area in France
