|Unfertilized, grazed calcerous
fens are often very rich in plant species and a lot of orchids can be
One of the characteristic species in calcerous fens is Epipactis
palustris - seen in the right picture. It is still quite frequent in
some parts of Denmark - especially on Seeland.
In Jutland good developed calcerous fens are rare and the best examples
are found along the coasts where there are calcerous shells in the
ground e.g. along the westcoast. Due to more high lying lime in the
soil of the Danish Isles, calcerous fens can be found a long way from
|Several rare species of
orchids can be found in the calcerous fens. Gymnadenia conopsea on the
left picture (here var. densiflora) now have only a few sites on the
danish isles. Also Dactylorhiza incarnata supsp. ochroleuca has become
very rare, while Liparis
loeselii and Herminium monorchis still can be found in
Other characetistic species from the calcerous fens are Dactylorhiza
incanata, Parnassia palustris, Linum catharticum, Briza media,
Pinguicula vulgaris, Juncus subnodulosus, Eriophorum latifolium, Carex
Carex hostiana and Carex flacca.
In 2005 the very rare Schoenus ferrugineus was discovered in 2 new
places and now has 3 places in Jutland in calcerous fens and a pair on
Seeland. The relative also found i calcerous fens - Schoenus
nigricans - has a few sites in Jutland and a single site on The Funen.
