Frangula alnus, commonly known as glossy buckthorn, is a shrub
that can grow to seven metres and is sometimes considered a
tree. Frangula alnus typically inhabits wet, shaded and acidic
soils. It can grow in soils of any texture. In North America,
wetlands are invaded by Frangula alnus. Frangula alnus is also a
typical woody pioneer during the succession of drained mires and
conveyed wet meadows, being overgrown and substituted by forest
vegetation. The invasion of Frangula alnus into forests and
riparian areas in the North American region has alarmed
foresters and conservationists. Frangula alnus attains high
cover in the understorey and tree seedling density and diversity
is known to be inversely related
