This association, dominated by Nymphoides peltata, occurs in lowland eutrophic fishponds, but historical records are also from oxbows, alluvial pools and mesotrophic water bodies. It occurs in 50–150 cm deep water, but tolerates drops of the water table to the level of the bottom and indeed requires such drops for seed germination. It grows in water bodies with mineral bottom, therefore it is common in early successional stages but it declines with accumulation of organic sediments. Its localities are scattered in warm areas across the country, but in many historical localities this vegetation type disappeared due to strong eutrophication, terrestrialization and changes in fishpond management. At the same time, N. peltata has been introduced as a decorative plant to several fishponds even in cooler areas.
