Tveitaneset, an exposed point in Nedstrandsfjorden,
Rogaland county, was in 1977 protected by law due to the occurrence of oceanic
evergreen forests typical of the district. The
bedrock consists of mica schist, but without
especially high calcium content; the flora is therefore dominated by mainly oligotrophic
species. The climate is humid, with a yearly
precipitation of about 1751 mm and a favourable combination of high summer temperatures
(slightly above 16oC in July) and mild winters
(January mean temp. above 0oC). Along a dry-wet gradient, plant communities either
belonging to or closely related to the following
pine forests are found. Cladonio-Pinetum (and
a moss-dominated variety), Barbilophozio-
Pinetum, Vaccinio-Pinetum, and Vaccinio uliginosi-Pinetum. The community names refer
to Kielland-Lund (1973). Lack of differential
species makes an exact phytosociological
determination difficult. This is a problem often
met with in Western Norway. The seashore mainly consists of exposed cliffs, with an
interesting transition through boulder and
stone shores to a small sand beach in the bay
east of Tveitaneset. Amongst the total of 91
species of vascular plants found are Circaea
intermedia, Goodyero repens, and several
oceanic or suboceanic species llke Ilex aquifolium,
Blechnum spicant, Erica tetralix,
Carex binenis, Narthecium ossifragum.
