The wild black cherry is an ornamental bush, imported from eastern North America, where it reaches tree heights. At the beginning of the 20th century, a bush variety was planted in the Netherlands on a large scale as undergrowth in production forests. This bush grows on poor sandy soils and in the dunes. It developed extremely rapidly at the cost of indigenous forest plants and became such a plague that foresters gave it the nickname 'forest pest'. Combating the forest pest has turned out to be a never-ending task. Remnants of the plant remaining in the ground simply re-root. And the very tasty cherries are carried over distances by both birds and mammals.
