Bakkatjorn, Seltjarnarnes
Bakkatjörn was protected in 2000. Bakkatjörn is an ice salt pond and has been that way since 1960 when the clay inlet that was there was closed off. A depression called Rásin (The Channel) once connected Bakkatjörn and Seftjörn, but the latter has now disappeared under urbanization.
The nature reserve covers an area of 14.9 ha.

Ecosystem
Recorded bird species in Seltjarnarnes increased by around 28% from 1957–1992. A survey conducted in 1986 revealed that the Arctic tern is the most common bird in the area, around 900 pairs, and thereof around 200 were to the north and east of Bakkatjörn. With the creation of Bakkatjörn around 1960, various species of duck began to make their way to Seltjarnarnes and later began to nest there following changed food conditions. Also taking advantage of the changes in landscape was the red-breasted merganser, a species that had been a common winter visitor on the sea around Seltjarnarnes. Red-necked phalaropes can be seen from mid-May to the latter part of August; in July and August, the birds number in the hundreds on Bakkatjörn and its surrounding area. Bakkatjörn is a bird feeding area, and near it are high-tide roosts and resting spots. It is believed that when the inlet was turned into a pond, there were great changes in animalcule life, as there was now a pond instead of mud.
