Table 3 Main species requiring vegetation control during the tree regeneration stage according to the indicator %A_{PC > 50, CC < 50} and area with species cover > 50% in open-canopy forests expressed in relative (%A_{PC > 50, CC < 50}, %) and absolute (area: 10³ ha) values, estimated at the national scale (excluding the Mediterranean region) between 2006 and 2018. Species are ranked by decreasing %A_{PC > 50, CC < 50} values. For each species, the species group to which it belongs is indicated. Species in bold or plain type correspond to the species requiring frequent or intermediate vegetation control, respectively
