“…In Europe, Dittrichia graveolens has been recorded as an alien plant species in Austria in 2001 [27,53], Germany in 2003 [49], Belgium in 2004 [37], The Netherlands [40] and Switzerland [13] in 2005, United Kingdom in 2006 [52], the Czech Republic in 2008 [47,48], Slovenia in 2009 [22], Slovakia in 2014 [33], Poland in 2015 [35,45,36], and Hungary in 2016 [57]. The first records of the species in Central Europe, according to existing studies [33,35], were made in Germany, Austria and Slovenia.…”

“…The first records of the species in Central Europe, according to existing studies [33,35], were made in Germany, Austria and Slovenia. It is presumed that it spread from there to the neighbouring countries, especially eastwards [35,33], with multiple studies indicating a remarkable speed in the propagation to new areas in Poland [36]. According to Brownsey et al [10], concerning the native occurrence of Dittrichia graveolens in Southern Europe and its ecological preferences, the species requires sunlit environments and terrain with low vegetation cover, having a highly reduced establishment success in habitats covered by dense vegetation.…”

“…Across its natural range Dittrichia graveolens grows mainly in alluvial floodplains, riparian woodlands and margins of tidal marshes. However, in its non-native areas it occupies disturbed habitats along roadsides with ruderal vegetation, arable fields, wastelands and gravel quarries [11,36]. Outside its range it can also occur in nitrophilous communities [11].…”

Dittrichia graveolens (L.) W. Greuter, an invasive plant species of Mediterranean origin, is recorded for the first time in Romania. We found the species in October 2020 in two separate locations along the main highway that connects Brașov and Sibiu cities, in Southern Transylvania, central Romania. We present here the first data concerning the species occurrence in the investigated area, its observed habitat, local distribution and accompanying species. We presume that the main vector for the introduction and dispersal of this species in Romania is the high traffic density along the major roads. Dittrichia graveolens has proven its invasive potential in other regions of Europe and North America of similar temperature and precipitation regimes under an overall temperate climate. Consequently, taking into account its fast dispersal, especially in the more favourable habitats for its establishment that exist along the major roads from the lower altitudes and the riparian communities from the western, southern and eastern parts of Romania, we conclude that close monitoring of the species occurrence should be undertaken in order to better assess its full invasive potential in our country and to reduce the risk of impact on natural plant communities.

“…The fastest spreading alien plant species along roadsides in Central Europe are Dittrichia graveolens (L.) Greuter and Senecio inaequidens DC. (Heger & Böhmer, 2005;Kocián, 2015Kocián, , 2016Kozłowska-Kozak et al, 2019;Szatmari & Hurdu, 2020).…”

“…The species started to spread rapidly in Europe only in the second half of the 20th century and particularly fast in the first two decades of the 21st century. Dittrichia graveolens is now recorded Austria (Essl & Rabitsch, 2002), Belgium (Verloove, 2006b), the Czech Republic (Pyšek et al, 2012), Denmark (Pedersen, 1961), Germany (Dettmar, 1991;Radkowitsch, 2003), Hungary (Takács et al, 2016), the Netherlands (Meijden, 2005), Poland (Kocián, 2015;Wróbel, Nobis, 2017;Kozłowska-Kozak et al, 2019), Romania (Szatmari & Hurdu, 2020), Slovakia (Király et al, 2014), Slovenia (Frajman & Kaligarič, 2009, Switzerland (Ciardo & Delarze, 2005), and United Kingdom (Sell & Murrell, 2006). Dittrichia graveolens is alien to Australia, New Zealand, South Africa and North America and is considered a hazardous invasive plant in some regions (Given, 1984;Esler, 1988;Parsons & Cuthbertson, 2001;Brownsey et al, 2013).…”

Dittrichia graveolens (Asteraceae), rapidly spreading along European highways, recorded in Lithuania

For a long time, railways were the main pathway for the accidental introduction of alien plant species, but now highways and other roads are becoming increasingly important in this process. Considering that Dittrichia graveolens is spreading rapidly along highways in Central Europe and neighbouring Poland, a targeted search was conducted in Lithuania in 2023. Dittrichia graveolens was recorded at two sites along the Kalvarija–Kaunas highway (Kazlų Rūda district, in the environs of Pentupiai, and Kaunas city, in the environs of Jonučiai). At both sites, the species occupied relatively compact stands consisting of several hundred individuals, suggesting that the stands were formed from locally matured seeds. The mean number of flowers per capitulum in Lithuania in 2023 was 20.5 ± 4.9, and the realised fecundity was 89.7% of the potential fecundity. It is presumed that the seeds of Dittrichia graveolens were accidentally introduced into Lithuania by trucks, probably attached to tyres. Currently, this species is classified as a casual alien, but its naturalisation is expected. The study revealed that the first record of Dittrichia graveolens in Poland was not in 2013, as previously reported, but more than 20 years earlier, in 1990, near Kraków, at the slag deposit site of the Nowa Huta Steelworks.
