Schlankseggenried
The slender sedge ( Caricetum gracilis ; also: Spitzseggenried) is a plant community whose characteristic species is the slender sedge ( Carex acuta = C. gracilis ).
Typical locations are banks of ditches and ponds as well as deep depressions in moist meadows with a high groundwater level on soils rich in nutrients and bases that are periodically flooded. Preference is given to wet in general, meso - eutrophic , but little with nitrogen supplied Niedermoortorfe , Anmoor -, Moor - and wet Gleye .
In Slim harrow vineyards often is primary Verlandungs companies, but to fallow secondary spare companies from floodplains conical Brüchern or riparian forests within formerly extensively used grassland .
The stocks are mostly limited to the high tide area with high standing, slightly fluctuating and weakly agitated groundwater. In winter or spring it can be flooded by emerging groundwater or flooding. After the sites have been drained, the slim harrow has a long persistence capacity; with better ventilation of the soil, however, it is displaced by species such as cane grass ( Phalaris arundinacea ).
Typical sub companies ( subassociations ) are, inter alia, meadowsweet ( Filipendula ) on dehydrated and eutrophic locations and comarum palustre ( Potentilla palustris ) in unfavorable nutrients to acidic fen soils.
