EVALUATION OF THE INCIDENCE OF INVASIVE NEOPHYTES IN THE SKALICKA MORAVKA NNM

National NatureMonument (NNM) Skalicka Moravka is characterized by a abundant biodiversity of rare communities linked to regular overflowed alluvial gravel deposits due to increased flows. Kadubec and Svec mapped territory NNM in 2007 and 2009 along with Blahuta (2013) to determine the level of invasion in meadow Moravka by the knotweed (Reynoutria spp.) and other neophytes. However this study maps biodiversity of native species and their interactions with introduced species on bedloadstreams. Territory NPP was interspersed with a grid (50 x 50 m), which contained 454 nodal points. At every point was made phytosociologicalreleves of a particular species. The summer aspect (which is in fact influenced byReynoutria spp.) of 2014 has shown with 140 plants abundances expressed total coverage to57.1 % of the area, 45 tree species (56.2 %) and 18 neophytes (10.0 %) classified according Pysek et al. inCatalogue of alien plants of the Czech Republic (2012). Coverage was evaluated for herbal, woody and shrub layer. The tree and shrub layers were evaluated according to theClassification of tree classesby Konsel (1931). Maps for each occurring species can be drawn based on the coverage and also disappearing species beneath the level of knotweed invasion can be determined. This is a prime study of mapping species diversity abundances after herbicide application to the surface area affected byReynoutria spp.Finally, the unpleasant result of ingrown nature trails neophytes that hinder permeability along the river Moravka.
