The horizontal and vertical structure corresponds to that of M4, M5, and M6. Phytocoenoses predominate here that are formed from components of the interfluvial steppes (Stipa capillata, Stipa lessingiana, Festuca valesiaca, Koeleria macrantha, Agropyron cristatum subsp. pectinatum etc.) as well as from typical steppe psammophytes (e.g. Stipa anomala). Carex supina occurs as a co-dominant species. Amongst the herbs one finds general euxerophytic steppe species of sandier-loamier soils and psammophytes. Euryxerophytic steppe plants are also generally distributed.

M7a (standard biome): 

Biome:

Grass mix: grass, meadow_fescue, small_fescue, kentucky_bluegrass, dead_grass, wavy_hair_grass, common_meadow_grass

Small clumps of alpine_sow_thistle, wormwood and simbelmyne

Scattered: wood_horsetail, wild_parsley and cross_leaved_heath

‍

M7b (wetter areas):

Biome:

Grass mix: grass, meadow_fescue, small_fescue, kentucky_bluegrass, common_meadow_grass

Small clumps of marsh_ragwort and alpine_sow_thistle

Scattered: wood_horsetail, wild_parsley

‍

M7c (disturbed ground):

Include patches of dirt

Biome: either of the above

Grass mix and other plants: again, may be identical to either of the above, but the 7a mix is more likely (these are meant to represent former campsites and grazing areas, which I’d think would be on drier ground)

Distinctive features: wormwood is more common
