Beryozovye Islands (Russian: Берёзовые острова; Finnish: Koivisto; Swedish: Björkö, lit.
The islands are situated at the head of the Gulf of Finland, just outside the town of Primorsk on the Karelian Isthmus.
There are 15 islands in the group, the largest of which is Bolshoy Beryozovy (Large Berezovy, Finnish: Koivistonsaari).
It has been designated an Important Bird Area (IBA) by BirdLife International because it supports populations of many species of waterfowl and gulls on passage.
Place names were russified after 1947 concurrently with the rest of the formerly Finnish Karelian Isthmus occupied in 1944.
