The sections below cover the most common forms of bracken and scrub in the Welsh landscape. There are many other scrub forming species in Wales, such as dogwood (Cornus sanguineus) and wayfaring tree (Viburnum lantana), but these are the species that you are most likely to come across. On sand dunes, sea buckthorn (Hippophae rhamnoides) can also be a significant presence: this species is covered in the ‘Coastal dunes’ section.
