Indication as to whether invasive or non-invasive alien woody species («tree or shrub neophytes») ≥12 cm in diameter at breast height (dbh) dominate the growing stock, i.e. account for at least 50% of the growing stock – in three classes. The classification as «invasive» is based on the 2022 publication «Invasive alien species in Switzerland» of the Federal Office for the Environment (FOEN) (UW-2220-E).
