| dc.description.abstract | Ve střední Evropì se na mezických stanovištích místy dosud vyskytují reliktní lesní i nelesní vegetaèní typy, jejichž druhové složení je do značné míry podobné jihosibiřským hemiboreálním lesům a přirozeným trávníkům. Jejich předchùdci se mohli ve středoevropské krajině hojně vyskytovat v příznivějších obdobích posledního glaciálu a ve starším holocénu. Tyto ancestrální vegetační typy nemohly být na celém území střední Evropy homogenní, z čehož zřejmě částečně vyplývají floristické a ekologické rozdíly mezi současnými reliktními společenstvy. | cze |

| dc.description.abstract-translated | Vegetation is a dynamic system of interacting plant populations. In spite of this dynamism, different vegetation types exhibit a variable amount of inertia in species composition. For this reason, the current vegetation of Central Europe is a heterogeneous mixture of plant communities of different age, depending not only on site conditions, but also on the history of vegetation development. We use the term “relict vegetation” for vegetation with an extraordinarily high proportion of species or species combinations which used to be more abundant in the past and may thus be considered as remnants of their wider past distribution. Although there is an almost infinite number of unique local histories of plant populations and their sites, within which a number of milestones might be identified, only two kinds of vegetation relicts are frequently distinguished in Czech botanical literature: 1) Glacial and Early Holocene relicts, i.e. remnants of plant communities widespread during the last Glacial period or the subsequent period of the Early Holocene but retreated mostly due to the spread of shady forests during the mid-Holocene; and 2) cultural relicts, i.e. vegetation types shaped by human activities which used to be more common in the past but have recently been abandoned. In this study we focus on relict vegetation on mesic sites at lower altitudes of the Czech Republic. Here, natural vegetation is represented mostly by oak-hornbeam and beech forests (Carpinion, Fagion) and semi-natural vegetation mostly consists of nutrient-rich mesic grasslands (Arrhenatherion) and relatively species-poor types of semi-dry grasslands (Bromion erecti). Although mesic lowland and upland sites were predominantly intensively managed in the past, we suggest that in some places ancient vegetation types were preserved both in forest and non-forest habitats. | eng |
