The Symposion in Lindabrunn is the second largest contiguous area of dry grassland on the Thermenlinie after the Perchtoldsdorfer Heide, with numerous rare animal and plant species such as the large cowbell, spring adonis, Austrian wreath gentian, yellow flax, the rare quendel snail and the yellow flax bee, which was only discovered in 2020. In addition to sheep grazing, regular scrub clearance is of great importance for conservation. Help preserve this outstanding natural area!
