Local extinctions of threatened species of Pedicularis L. in agriculture landscape of southeastern Bohemian-Moravian Highlands

Popis výsledku v původním jazyce

The general extinction of organisms belongs to significant environmental problems through the world. In addition to the rare species which long-term occurred only on several localities, we face today the problem of a massive retreat of number of species that perhaps seven decades ago were considered to be relatively common. Primarily competitive weak species retreat or local extinct in behalf of the stronger competitive ones, the better adapted to human-modified eutrophic agriculture landscape. Using very detailed local floristic data of Pedicularis palustris and P. sylvatica north of Velké Meziříčí (southeastern Bohemian-Moravian Highlands), we demonstrate continual retreat of species abundances in two-time periods, recent situation with state approximately twenty years ago. Pedicularis palustris was historically known from two localities in the region, both of them disappeared and the species has not been found for more than ten years. Pedicularis sylvatica survives only on a third of the sites known from 1990s, with a large decrease in abundances. Multiple factors, eutrophication, abandonment of land, warmer and drier climate periods, unsuitable local-management practices in some cases, speed up significantly the process of local species extinction, within a relatively short time period of twenty years. Similar fate has met also other species of plants or animals in different regions.
