Marshes dominated by Carex disticha occur in shallow depressions in wet meadows, on the edges of oxbows and alluvial pools, in outer zones of the shores of fishponds, and in wet ditches. Soils are usually mineral, rich in nutrient and bases, in some places slightly saline. The soil surface is flooded for a few days or weeks in spring, but it can dry out for long periods in summer. This association occurs in lowland and colline areas of the Czech Republic.
