Erechtites hieracifolia (L.) Raf. ex DC. (Asteraceae Bercht. & J. Presl), the new alien species for the Kyiv Polissia

Abstract

Information about floristic record of Erechtites hieracifoliа (L.) Raf. ex DC. (Asteraceae Bercht. & J. Presl) at the territory of the Chernobyl Radiation and Ecological Biosphere Reserve and National Nature Park "Нolosiivsky", new for the Kyiv Polyssia alien species was presented. This species has north american origin, according to the time of arrival it is kenophyte, according to the skidding method – xenophyte, on naturalization level – kolonophyte. Firstly in the region of study this species was collected in 2018 in vicinities of former village Ilovnitsa (northern part of the village) of Ivankov district of Kyiv Oblast. Later, in 2019 E. hieracifoliа was noted in two another sites of biosphere reserve (vicinities of former village Klyvyny of Ivankiv District, Kyiv Region and former village Kamianka of the same administrative units). Total revealed more than 60 species plants, in vegetative state (prevailed) and also in generative state. Plants were noted sporadically on forest edges and roads in composition of unformed plant communities. In 2019 this species was also found on the territory of National Naturе Park "Нolosiivsky" (Sviatoshin-Bilychі branch) where individuals of the species were found singly or in small groups (5–10 plants). In total, 60 plants of E. hieracifoliа were noted here. Probably they came to the study region recently – some years ago, skid occurred on high roads which plants used as wind corridors flanked by forests, and also on local ways; it is possible that diaspores distribution is carried out also by birds. Schematic map of species distribution in the region was presented. Data about primary and secondary areas of the E. hieracifoliа, its ecological and coenotic peculiarities were presented. The main stages of history of skidding and further distribution of the investigated species in Ukraine were reconstructed; the main directions of it distribution is connected with northern and western regions of the country. Currently, the species tends to actively spread into another regions of Ukraine. In Europe it belongs to invasive species and demands control of spread.

Vegetation changes within the Chornobyl Exclusion Zone, Ukraine

“…M. Bieb., and Solidago canadensis L., which are a huge problem in the Polissya region, are almost non-existent in the area (PASHKEVYCH & BURDA, 2017;KOLOMIYCHUK ET AL., 2019;PROTOPOPOVA & SHEVERA, 2019). It should be noted that the first post-pyrogenic stage of dry pine forests is attended by alien species and differs significantly from the classical scheme.…”

“…In addition to the two localities in the Svyatoshyn Forest (within the Svyatoshyn-Bilychi branch of Holosiivskyi National Nature Park) in the western part of the city of Kyiv reported by Kolomiychuk et al (2019), we found rather large colonies of E. hieraciifolius on 2 August 2020 within the city limits of Kyiv in the Pushcha-Vodytsya Forest, in the northwestern part of Kyiv City, north of the city tram station "Spetsdispanser" (coordinates: N 50.526238, E 30.399593, and adjacent areas in the forest compartments 103 and 104 of the Pushcha-Vodytsya Forestry; Fig. 5, B; E2, B).…”

“…62.4 of the ICN: Turland et al, 2018), native to North America and known as naturalized and often invasive in Europe and some other parts of the world (see Belcher, 1956;Cameron, de Lange, 2002;Barkley, 2006;Darbyshire et al, 2012, etc. ), is now actively spreading in western and northern regions of Ukraine (see Orlov, Yakushenko, 2011, Tretyakov et al, 2011Tokaryuk et al, 2017;Kolomiychuk et al, 2019, and references therein), as well as in other countries of Central and Eastern Europe (e.g., Górski et al, 2003;Tretyakov et al, 2011;Bartoszek, 2019;Gudžinskas, Taura, 2020;Zaniewski et al, 2020, etc.). Its invasion in Polissya (the northern forest zone) of Ukraine and adjacent regions of Belarus seems to be especially active at present.…”
