Occurence of buckthorn (Hippophaës rhamnoides L.) in the mainland coast and archipelago of Rauma in the Southwestern Finland was surveyed during 1934-1936. The species is coastal, growing most prominent in the islands of central zone of the archipelago, while it is rare in the outermost archipelago and loses competition to other vegetation in mainland. The main competitors in the innermost islands are black alder (Alnus glutinosa (L.) Gaertn.) and Norway spruce (Picea abies (L.) H. Karst.) and in the outermost islands black alder and common juniper (Juniperus communis L.). Seawater and ice can cause damage to buckthorn, but it resists wind well. The species grows well both on fine and coarse gravel.
