The diminution of biological diversity is widely observed throughout the world in a variety of plant communities. Species protection itself is an insufficient form of preservation of the Siberian Iris population. A serious threat to this species is systematic diminishing of its typical habitat – Molinietum caeruleae plant community, i.e. Molinia meadows on calcareous, peaty or clayey-silt-laden soils. Its maintenance is possible only through conservation and restoration of the plant communities in which it occurs.
