This community is dominated by Hordeum murinum, a winter-annual grass. It develops in May and June in cities, villages and along roads in agricultural landscapes. Habitats include dry and sunny margins of roads, disturbed lawns and vegetated strips at the footings of walls or fences. It occurs in lowland and colline landscapes across the Czech Republic.
