Eulittoral zone: e.l.

The Localities Investigated
The localities where the seashore lichens
were collected are plotted on fig. 1.
Locality 7, Dalar, is located 1 km south
of the village Viðareiði, on the island of
Viðoy. The beach is a vertical cliff which
rises 30 m above the sealevel. It forms a
small slope into the terrestrial region with
scattered birdstones in between. The maxi-
mum height of the investigations area is 30
m from sealevel. The locality faces east,
and is directly exposed to the sea.
Locality 57, Hvítanes, is situated on the
island Streymoy. It faces NE and is rela-
tively well protected from the heaviest
wind directions. Fig. 2 shows a picture
from the locality.
Locality 59, Hoyvík, is located on the is-
land Streymoy 3 km north of Tórshavn.
The aspect of the rock surface is S, and it is
exposed to the strongest wind directions.
