20.500.12556/DKUM-95689 Spontano širjenje lesnatih vrst v mestnih parkih Ljubljane, Maribora in Zagreba magistrsko delo Spontaneous spread of woody plant species in the urban parks of Ljubljana, Maribor and Zagreb Raziskava obravnava spontano pojavljanje lesnatih rastlinskih vrst v urbanih parkih treh srednjeevropskih mest: Ljubljane, Maribora in Zagreba. Glavni cilj raziskave je bil osvetliti vlogo mestnih zelenih površin kot pomembnih žarišč za spontano pojavljanje tako domorodnih kot tujerodnih vrst, s posebnim poudarkom na vrstah z invazivnim potencialom. Delo prispeva k boljšemu razumevanju procesov, ki oblikujejo sestavo urbane flore v kontekstu podnebnih sprememb, biotske homogenizacije in vse intenzivnejše urbanizacije. Podatki so bili zbrani z natančnim terenskim delom, ki je vključevalo sistematičen pregled izbranih mikrolokacij znotraj posameznih parkov. Vzorec je bil zajet v različnih vegetacijskih sezonah, z namenom celovitejšega zajema spontanega pojavljanja vrst. Posebna pozornost je bila namenjena morfološki določitvi vrst, analizi življenjskih oblik, načinov širjenja ter določitvi geografskega izvora posameznih taksonov. Skupno je bilo zabeleženih 131 vrst lesnatih rastlin, pri čemer so bile najpogostejše domorodne vrste., - Med tujerodnimi so prevladovali taksoni z izvorom iz Severne Amerike in Azije. Najpogostejši način razširjanja je bila zoohorija, sledila je anemohorija, kar kaže na pomembno vlogo živali in vetra pri sekundarni disperziji. Glede na življenjske oblike so prevladovala drevesa, vendar je bila prisotna tudi znatna številčnost grmovnic in vzpenjavk. Skupno je bilo evidentiranih 14 invazivnih in 17 potencialno invazivnih vrst, kar opozarja na potrebo po rednem spremljanju in ukrepanju. Rezultati potrjujejo pomen raznolikosti habitatov in mikrolokacij znotraj urbanih parkov kot ključnih dejavnikov pri spontanem pojavljanju in potencialnem razširjanju lesnatih rastlinskih vrst. Delo izpostavlja tudi potrebo po dolgoročno usmerjenem in trajnostnem upravljanju mestne vegetacije, ki bo temeljilo na ekološkem razumevanju urbanih ekosistemov ter preprečevanju širjenja invazivnih vrst. Magistrsko delo je bilo delno sofinancirano iz projekta IŠRI:UM za leto 2025. The study examines the spontaneous occurrence of woody plant species in urban parks in three Central European cities: Ljubljana, Maribor, and Zagreb. The main objective of the study was to highlight the role of urban green spaces as important hotspots for the occurrence of both native and alien species, with a particular focus on species with invasive potential. The work contributes to a better understanding of the processes that shape the composition of urban flora in the context of climate change, biotic homogenisation and increasingly intensive urbanisation. The data were collected through detailed fieldwork, which included a systematic survey of selected micro-locations within individual parks. The sample was collected during different vegetation seasons in order to capture the most comprehensive range of species possible. Special attention was paid to the morphological identification of species, the analysis of life forms, modes of dispersal, and the determination of the geographical origin of individual taxa. A total of 131 species of woody plants were recorded, with native species being the most common, while among non-native species, taxa originating from North America and Asia predominated. The most common mode of dispersal was zoochory, followed by anemochory, indicating the important role of animals and wind in fruit and seed dispersal. In terms of life forms, trees predominated, but there was also a significant number of shrubs and climbers. A total of 14 invasive and 17 potentially invasive species were recorded, highlighting the need for regular monitoring and action. The results confirm the importance of habitat diversity and micro-locations within urban parks as key factors in the occurrence of plant species. The work also highlights the need for long-term, sustainable management of urban vegetation based on an ecological understanding of urban ecosystems and the prevention of the spread of invasive species. The master thesis was funded partly by the IŠRI:UM 2025 project. mestni parki spontano pojavljanje lesnate rastline invazivne vrste urbani ekosistemi Slovenija Hrvaška. urban parks spontaneous occurrence woody plants invasive species urban ecosystems Slovenia Croatia. true true false [L.
