Classification of trees and shrubs ≥12 cm in diameter at breast height (dbh) into the three classes: «introduced tree species», «native tree species» and «indeterminable and/or shrub species». Introduced tree species are tree species that have been intentionally or unintentionally introduced by humans into habitats outside their natural range. With this classification attribute, which is used in all inventories, the Japanese larch (L. kaempferi) and introduced arboreal willow species are not counted as introduced tree species, because they are recorded together with related native species in certain inventories. The Japanese larch (Larix kaempferi), for example, is grouped together with the European larch (L. decidua). Reference: Field Survey (MID 50: Baumart)
