Vegetation of the Czech Republic
Trifolio-Melampyretum nemorosi Dierschke 1973
This herbaceous community is dominated by Melampyrum nemorosum and contains species of mesic meadows and those typical of the understorey of mesic broad-leaved forests. It is widespread in cooler and wetter colline landscapes, and occasionally occurs also in submontane areas. It occupies sites of potential oak-hornbeam or beech forests and often occurs in canopy openings or along the edges of these forests. The community has a scattered distribution throughout the country, but its true extent is still not sufficiently known.
