Beruletum erectae

Photo on

This association is dominated by the umbellifer Berula erecta and occurs in brooks and shallow pools. It occurs in three different morphological forms: (1) upright, emergent stands in shallow water or on wet banks; (2) stands with leaves floating on the water surface in deep, slow streams; or (3) submerged stands with strongly branched stems in fast streams. The water in which this community is found tends to be rich in nutrients, calcium and dissolved oxygen. Submerged parts of B. erecta and other species intercept and accumulate organic material and mud, and significantly contribute to terrestrialization. This association is most common in lowlands in the northern part of Bohemia.
