and emerged from the sea after around 500 AD. This process continues, with the land rising by about per century. The existing islands expand and new islands slowly emerge. As the islands emerge they are battered by waves and ice forming large fields of rubble. The bedrock and the boulder beaches consist of granite with large eyes of feldspar. The water is brackish with salinity of only around 0.2%.

Nature reserve

Islands

The Likskär nature reserve, the only one in the Kalix archipelago, was established in 1969. It includes 25 islands and smaller islets, and is part of the European Union's Natura 2000 network. The largest island, Getskär-Renskär, is the most visited. There are traces of old fishing villages, including simple dwellings and mounds for drying nets, and several mazes made of boulders on Likskär and Renskär. Fishermen's houses on Renskär and Likskär are now used as holiday homes. Visitors may camp in designated areas and make fires using wood that they bring. Visitors may hike, pick berries and mushrooms and fish, but hunting and snowmobiling are prohibited. During the bird breeding season of May June and July boats must not come closer than to the islands of Ligogrunnan, Splitterören, Olnisbrottet, Mellangrundsbotten and nearby islets.

Flora

The oldest islands have dense forest cover. Newer ones may have stands of juniper, meadows or bare gravel. Many of the beach plants of the Bothnian Bay are found in the nature reserve. These are hardy plants that can survive the scraping motion of the ice sheets that form in winter and advance as the ice expands, and can handle tides of brackish water that vary by up to . Away from the shore there are meadows with plants such as
