Jaroslav Blahuta: Habitat mapping NPP Skalická Morávka as a basis for monitoring regeneration Reynoutria spp. printed after the intervention of the herbicide. The aim of this thesis was to map the habitats of the Catalogue of habitats (Culek et al., 2010) in the NPP Skalická Morávka and their level of invasion Reynoutria spp. as a basis for monitoring areal intervention herbicide. NPP is the subject of the protection of the natural stretch of the river Morávka in gravel sediments with their characteristic communities. These communities are bound occurrence of rare and endangered species (for example Myricaria germanica). Territory NPP was interspersed with square nets (50 x 50 m), which contained 454 nodes. At every point was made simplified the occurrence and registration of a particular species, found coverage representativeness, degree of degradation and the presence of dead wood. Based on these characteristics was to characterize habitats with regard to the level of invasion of neophytes. Overall the 454 mapping points to characterize habitat 13 by the concept of Culek et al. (2010). The percentage of each habitat is as follows: L2.2 (54,75 %), L2.4 (0,66 %), L3.2 (3,09 %), K2.2 (11,92 %), M1.4 (0,22 %), M4.1 (9,27 %), M4.2 (0,22 %), X7A (5,52 %), X7B (10,82 %), X12A (0,66 %), X12B (0,22 %), V4B (2,21 %) and T1.1 (0,5%). The overall level of invasion NPP Reynoutria spp. is 61 %. The highest abundances reached in natural habitats L2.2 (61 %), K2.2 (55 %) and M1.4 (52 %). Invasion of Impatiens glandulifera is 26 %. The highest abundances stood near the river (habitat K2.2, M1.4 and X7B). In terms of representativeness was most often to characterize transitional habitats with 82.9 % of the mapping points. According to the degree of degradation was 22 % of the nodes proved negative factor (most often the occurrence of neophytes, or illegal dumps).Dead wood is found only 6 % of the territory. The work represents a good basis for future monitoring and management optimization.
