During the period of the years 2000-2002 monitoring of the dragonflies and their habitats in the Paríž stream catchment was realised. From the study area were recorded 34 species (957 specimens) of dragonflies. What concerns species protection 17, species of these are registered in the Slovak Red List and 8 species are protected by law in the Slovak Republic. The endangered and the rarest species in the area are e.g. Coenagrion scitulum, Libellula fulva, Brachytron pratense, Epitheca bimaculata, Somatochora flavomaculata etc. According to the origin, 24 species from Mediterranean region (faunistic centre) dominate. Twenty six species of dragonflies prefer stagnicolous water habitats, only Calopteryx splendens and Platycnemis pennipes are rheophilous. The species Epitheca bimaculata, Somatochlora flavomaculata and Sympetrum danae are rare and they prefer marsh habitats. The number of indigenous species is relatively high, several are migrant e.g. Crocothemie eryhraea, Aeshna isoceles, A. mixta. The dragonfly community structure and the types of habitat were described with the using of CANOCO statistical packages (indirect gradient analysis, procedure PCA, DCA). We identified the stagnicolous Lestes-Sympetrum-Aeshna and euryhtopic Orthetrum-Libellula depressa odonatocoenosis but no rheophilous communities. The particularity of the Paríž stream catchment is the high significance of macrophytes as environmental variables. The results of biomonitoring confirm the importance of the man-made water habitats (sand-pits, marshland-pit, drain-streams and ponds) in the study area.
