The common swamp bear moss or moor bear moss ( Lycopodiella inundata ) is a representative of the bear moss plants ( Lycopodiophyta ) found in moors .

features

Bog moss is a perennial plant with creeping stems, the above-ground creeping shoots of which are 2 to 10 centimeters long. In habit it resembles deciduous mosses (especially Polytrichum ). The sporangia-bearing sections stand upright and are 4 to 8 cm long. The sporangial ear is indistinctly separated from the shoot. The leaves are spiral and curved upwards. The sporophylls are broadly ovate at the base and have a serrated leaf edge. The spores are 40 to 46 micrometers in diameter and ripen from August to October.

The number of chromosomes is 2n = 156.

ecology

The marsh moss has a low, deciduous shoot axis that creeps on the ground and is rooted in its entire length, and which annually only forms a sessile, terminal ear of spurs. The aboveground prothallium has green assimilating lobes. The species is a light plant .

Occurrence and endangerment

The marsh moss is a (temperate) boreal, slightly subatlantic floral element. The swamp bear moss is circumpolar .

In the northern hemisphere it occurs in Europe and North America (especially in the eastern part), it is rarely found in East Asia; especially in Europe it occurs mainly in the cool and temperate zones (north to 66 ° north latitude), east to Finland, western Russia and Bulgaria, south to northern Portugal, the Pyrenees, the Alps and the Carpathians. Individual occurrences are found in the northern Apennines. It is absent in the Mediterranean region.

Population of the swamp bear moss with sporophylls

It grows on open bog - floors , in between bogs, on quaking in Moor Schlenken in wet dune valleys and on anthropogenic secondary locations. It occurs mainly on wet, moderately alkaline to acidic peat mud soils or on humus sand. It is a character species of the Rhynchosporetum in Central Europe.

Sumpf-Bärlapp climbs up to the montane altitude level , in the Alps also higher, up to 1700 m. In the Allgäu Alps, it rises on the Ziebelmoos near the Piesenkopf near Rohrmoos in Bavaria up to 1420 m above sea level.

In Germany, the marsh moss is rated as “endangered” overall, but in many federal states it is considered “critically endangered” or even “threatened with extinction”. It is therefore classified as a national type of responsibility within the National Strategy for Biodiversity of the Federal Government. In Austria it is "endangered" and is absent in Vienna and Burgenland. He is missing in Liechtenstein.
