Abstract
Žlezava nedotika je enoletnica iz družine nedotikovk, ki izvira iz himalajskega dela Azije. V Evropi je prisotna od 19. stoletja in je danes ena izmed bolj znanih invazivnih vrst. Razširjena je tudi v Sloveniji, zlasti ob rečnih obrežjih in na ruderalnih območjih. V magistrskem delu predstavimo stanje njene populacije na območju Krajinskega parka Ljubljansko barje v letu 2019. Popis smo izvedli na osnovi prostorskih podatkov iz prejšnje vegetacijske sezone s ciljem: ugotoviti morebitno širjenje lokalnega areala te vrste na izbranem območju v obdobju enega leta. Čeprav se v literaturi poudarja možnost hitrega širjenja žlezave nedotike ob vodnih telesih, teh trditev nismo mogli potrditi. Nismo zasledili veliko novih nahajališč, potrdili pa smo širjenje v okolici starševskih rastlin. Naši rezultati kažejo, da vodotoki Ljubljanskega barja zelo verjetno nimajo velikega vpliva na razširjanje obravnavane vrste. Rezultati popisov spremljevalne flore žlezave nedotike so s pomočjo ekološke analize potrdili, da vrsta daje prednost vlažnim in motenim rastiščem, vendar lahko preživi tudi v pogojih, ki nekoliko odstopajo od njenega ekološkega optimuma skupaj z generalisti in drugimi tujerodnimi vrstami. Na osnovi tega predvidevamo, da se bo njen areal v prihodnosti brez ustreznega ukrepanja zelo verjetno razširil po velikem delu Slovenije, z izjemo visokogorja in toplejših delov submediterana.

Title:State of invasive alien species' Impatiens glandulifera populations in Nature park Ljubljansko barje
Abstract:
Himalayan balsam is an annual plant from the balsam family, originating from the Himalayan part of Asia. It's been present in Europe since the XIX century and it has become one of the most recognizable invasive plants. It is found also in Slovenia, mostly in riparian zones and ruderal areas. In this thesis, we present the state of its populations in Nature park Ljubljansko barje from the year 2019. Mapping was based on data from the previous season, in aim of determining whether it has been spreading on the discussed area in one year. Although several authors often provide data of its fast spread by waters, we could not confirm that. Only few of the newly established populations were found, while the short distance local spreading nearby the parent plants was confirmed. Our results didn't point out the importance of Ljubljansko barje's water bodies in species' spreading. The results of accompanying flora's inventarization have confirmed the species' preference for moist and fertile habitats, although it was able to survive in ecological conditions somewhat different, surrounded by generalists and other allochthonous species. Due to those results, we assume that, without the proper management, distribution of the Himalayan balsam in Slovenia will expand in many of country's parts, except for the higher mountains and warmer parts of the Sub – Mediterranean region.
