H4 – Bromus erectus-Brachypodium pinnatum xero-mesic grasslands, dry tall herb communities and forest steppe meadows:
Xero-mesic clearings, grasslands, sometimes tall herb communities belong to this habitat type with variable origin and species pool. These grasslands are dominated mainly by grasses of broad leaves, such as Bromus erectus and Brachypodium pinnatum, more infrequently Arrhenatherum elatius, Bromus pannonicus, Stipa tirsa, Sieglingia (Danthonia) alpina. This habitat is rich in species, also in forbs, and holds forest remnant forest species. The actual extension is 12 000 ha, the two-third of that can be found in the Északi-középhegység (8000 ha). It occurs in several places, but with much smaller area (2700 ha) in the Dunántúli-középhegység, and sporadically in the eastern part of Dunántúli-dombság (700 ha), northern part of Nyugat-Dunántúl (280 ha), and in the western part of Alföld (Mezőföld, 300 ha). It can be found in small amount also on Kisalföld, in the western part of Dunántúli-dombság, and in the northern part of the Duna-Tisza köze. It is mainly a colline habitat type, which is rare in the lowlands, occurring most typically in regions of dry, forest steppe climate, often under subcontinental influence. Whereas it is absent from Alföld, which is the driest part of the country – but this can be explained, at least partially, by the land-use history of lowland steppe landscapes (ploughing all the areas suitable for agriculture). It is relatively easy to identify this habitat, but sometimes the separation from other dry steppes (H3a, H5a), or from certain meadow types (E1) can be problematic.
