Application of phytosociological survey and GPS mapping in assessment of the elimination effects of invasive neophytes in the Morávka catchment
Lacina, Jan
After disastrous flood in 1997, more distribution of invasive neophytes, particularly Reynoutria spp., was noticed in lower course of the River Morávka (including Special Area of Conservation The Morávka floodplain). The invasive neophytes expand both in flood-plain forest and on gravel bars, one of the last habitats for critically endangered species Myricaria germanica in the Czech Republic. Since 2006 the project „Rescue of floodplain habitats in the Morávka catchment” has been developed for maintaining and sustaining of autochthonous species, supported by European Union within the framework of Life Program. The mechanical and chemical combination of agents is used to eliminate the population of Reynoutria spp. This can negatively affect the occurrence of other species. The methods of phytosociological survey and GPS mapping is used to assess the efficiency of elimination action and its negative impacts.
