This association occurs on fishpond margins, wet fields, dirt roads in precipitation-rich areas, and in sand pits. The habitat is usually flooded for a shorter time than in the other associations of the alliance Eleocharition ovatae. The most common substrate is acidic coarse sand, but the association also occurs on loamy-sandy or gravelly substrates with low pH. In the Czech Republic this association is most common in colline and submontane areas of the Bohemian Massif.
