In 2021, on the 10th anniversary of granting this protected area the status of a UNESCO site under the "Man and the Biosphere" programme, the Lithuanian Mint minted a 2-euro coin depicting nature motifs symbolizing the largest wetland in Lithuania, known as the "lake of birds". It contains the most characteristic species of Żuwintas - in the background there is a bittern reaching for a fire-bellied toad submerged in water, among the reeds on the right there is an aquatic warbler, and above it a flock of common cranes and a mute swan.
