The pilot phase of vegetation and the selected animal groups monitoring of reservoirs for the regulation and the drainage of rainwater in the Jaguar Land Rover complex in Nitra began in 2019. We have confirmed the occurrence of 66 vascular plant species. The initial stands of Typhetum angustifoliae, T. latifoliae and T. laxmannii are dominant in growth. We have recorded Phragmites australis, Schoenoplectus lacustris, Berula erecta, Carex pseudocyperus, Populus alba, Salix fragilis, Ranunculus sceleratus respectively. The surprising discovery is the rapid spread of the vegetation; some ponds have had a cover of macrophytic vegetation from 70 to 80 %. We have found 12 dragonfly species there in the course of the second year of them breed here. They are characterized by a high degree of dispersion and "r" life strategy; these species are referred to as “pioneer species”. The first aquatic dragonflies have inhabited newly formed aquatic habitats these are Ischnura elegans, I. pumilio, Anax parthenope, Crocothemis erythraea, Orthetrum brunneum, Sympetrum fonscolombii respectively. We recorded 26 spider taxa, the predominant juveniles, primarily from the family Lycosidae. European largest spider (Lycosa singoriensis) was dominant at the pond banks. We have observed the presence and higher abundance of detritophagous soil mites (Acari), springtails (Collembola), dipterans (Diptera), bugs (Heteroptera), cicadas (Auchenorhyncha) and especially orthoperoid insects (e.g. grasshoppers). We have recorded a year-on-year gradual qualitative and quantitative increase in invertebrates, indicating the stabilization of pioneer species. The continuous monitoring will prove the increase in the species richness, which signalises a stable trophic and refuge niche.
