Екобіологічні загрози поширення видів роду Heracleum на території міста Кременця Тернопільської області

Abstract

The article deals with the problem of the invasive species spread (Heracleum sosnowskyi and Heracleum mantegazzianum) which can constitute a significant threat to natural ecosystems, people and economy. The peculiarities of Heracleum distribution on the territory of Kremenets are revealed. As a result of the examination, 20 large colonies as well as about 35 single areas of Heracleum sosnowskyi and Heracleum mantegazzianum were found. The largest and the oldest habitats of Heracleum sosnowskyi and Heracleum mantegazzianum spreading were revealed on the territory of the WOG and AVIAS petrol stations and in the districts of the detour road. The total area occupied by the Heracleum in Kremenets constitutes 804 m 2 . The tendency to territory increase can be observed by 17.2% since 2010. Field studies describe 6 model places that represent the most widely distributed areas of Heracleum sosnowskyi and Heracleum mantegazzianum. Based on the analysis of the obtained results, the main habitats of distribution of invasive species were identified and mapping of their locations was performed. The main threats of uncontrolled spreading of dangerous plants were formulated. The most effective and safe methods of weed control were offered.

Giant hogweeds (Heracleum mantegazzianum and H. sosnowskyi) in Ukraine: distribution, ecological and coenotical features

“…The analysis of the current distribution of both H. mantegazzianum and H. sosnowskyi in Ukraine was based on geobotanical studies, herbarium collections of the M.G. Kholodny Institute of Botany and Chernivtsi National University, literature sources (Lukash and Zavyalova, 2003;Burda, 2007;Lukash, 2007;Bagatska, 2008;Naumov et al, 2009;Vykhor and Prots, 2012;Tokaryuk et al, 2012;Protopopova et al, 2015;Mykhalyuk et al, 2017;Grygus et al, 2018;Pashkevych, 2018;Tokaryuk et al, 2018;Khomyak et al, 2019;Oitsius et al, 2020;Koniakin, 2020, 2021;Dubyna et al, 2021;Lyubinska and Matvieiev, 2021;Korsun, 2022;Koniakin et al, 2022Koniakin et al, , 2023Records of alien..., 2023) and internet resources -UkrBIN (https://ukrbin.com), INaturalist (https://www.inaturalist. org).…”

“…Communities with the participation of giant hogweeds have been recorded in Latvia (Laiviņš & Gavrilova, 2003), Lithuania (Gudžinskas et al, 2015), Poland (Sobisz, 2007), Hungary (Kovács, 2003), Germany (Thiele and Otte, 2006), Czech Republic (Pergl et al, 2012) and other countries. Publications of Ukrainian researchers contain basic information on their distribution in different regions, in particular, mixed forests (Lukash and Zavyalova, 2003;Lukash, 2007;Protopopova et al, 2015;Khomyak et al, 2019;Grygus et al, 2018;Oitsius et al, 2020), broadleaved forests (Mykhalyuk et al, 2017;Korsun, 2022); forest-steppe part (Burda, 2007;Bagatska, 2008;Koniakin, 2020, 2021;Koniakin et al, 2023), the Ukrainian Carpathians (Simpson et al, 2011;Vykhor and Prots, 2012;Koynova and Shtoyko, 2015;Didukh et al, 2016;Tokaryuk et al, 2018;Pashkevych, 2018) and Crimea (Naumov et al, 2009).…”
