Schalkenmehrener Maar

The height of the maar above sea level is 420 metres (average elevation of the water surface).

Botanically, three different zones can be distinguished: the shore area, the raised bog and the slopes of the maar basin.

The slopes of the maar basin are dominated by a mix of dry grassland and woodland edge vegetation.

In addition to Breckland thyme and oregano, there is restharrow, hare's-foot clover, hop trefoil, narrow-leaved everlasting pea, musk mallow, clustered bellflower, downy hemp-nettle, fox and cubs, brown knapweed, greater knapweed, small scabious, woodruff and large communities of rosebay willow-herb.

Neophytes that may be seen include garden lupins and large-flowered mountain trumpets.
