Cyperetum micheliani

This association includes low-growing annual vegetation with Cyperus fuscus and Juncus bufonius, while Cyperus michelianus is rare in its stands in the Czech Republic. It occurs on periodically flooded river banks, in desiccating oxbows, on exposed bottoms of fishponds and fish storage ponds, in sand pits, banks of water reservoirs and in puddles. It is better adapted to substrate dessication than the association Polygono-Eleocharitetum ovatae, and it also occurs on substrates that are richer in calcium and salts. It occurs especially in warm lowland areas.
