Less intensively used parts of public green spaces can be transformed into colourful flower meadows with various herbs, grasses and flowers which would once again attract butterflies and birds, by no longer fertilising them and managing them in an extensive manner. Extensive management saves money and already is common practice in many communities. An extensively managed grass field can be converted back to a dense grass lawn by mowing it more frequently if its function requires this, for instance for an event or for temporary parking.
By removing the grass after it has been mowed from some parts but not from others, the difference in fertilisation will create differences among what grows and flowers there.
