Abstract
Carex is the most species-rich genus in the family of Cyperaceae. Carex with Phragmites australis or Bolboschoenus maritimus dominates in the building the plant cover of wet habitats. Value of mossy Carex as forage is too low, even in the hay [1]. Forage plants, as bottle sedge (Carex physodes, Carex subphysodes) growing on sand and sandy soil and Carex pachystylis growing on loamy grey soil, are distinguished by its high content in protein and being valuable forage plants [1].
