“…In this and in a coarser scale (i.e. HFMP) the observed richness is unique in the country (Bartha et al 2019). It is often supposed, however, that this richness is a result of the introduced aliens, mainly the neophytes (Kühn et al 2004).…”

Urbanization is one of the major causes of species loss and the homogenization of the world's flora. Our coarse-scale floristic mapping project of the largest south Transdanubian city, Pécs, is the first grid-based urban study in Hungary that reveals the current pattern of the vascular flora. Beyond the general description of the project, the species richness, the number of native, archaeophyte, neophyte and legally protected taxa are presented in the scale of the grid units (2.2 km2) and according to the residential area of the city. Relationships between the number and proportion of natives, archaeophytes, neophytes, protected species versus the proportion of built-up areas, forest coverage and elevation are estimated by linear regression models. Among the 1458 spontaneous or subspontaneous vascular plant species of the study area 131 are legally protected. The average number of species per grid unit is 338. Regression models show that the number of aliens decreases with forest coverage and increases with the rate of built-up areas, while number of natives shows opposite trends as a function of the same variables. These opposite trends lead to the conclusion that in the case of the vascular flora of Pécs the “poor get richer” theory is supported. Among the most frequent species hemicryptophytes, widespread, native and zoochorous plants are dominant. The most widespread four invasive taxa are native to North America.

The paper presents data on the distribution and habitat preferences of Polygonum arenarium subsp. arenarium in Slovakia. The study showed a rapid decrease in the number of localities in Slovakia in recent decades, due to destruction of sandy habitats. At present the taxon is considered to be very rare. We recorded it in stands of pioneer vegetation of the Festucetea vaginatae class developed on open sandy dunes, in the associations Festucetum vaginatae and Bassio laniflorae-Brometum tectorum.

“…We gathered the occurrence data from literature, personal communications of experts and our own records. To find current occurrences, we used the "Distribution atlas of vascular plants of Hungary" database (Bartha et al 2022). During literature scanning, we used Arcanum Digitheca (https://www.arcanum.com/ en/), MATARKA (Hungarian Periodicals Table of Contents Database, https://matarka.hu/) and ad hoc literature scanning.…”

Ornamental plants constitute a major source of invasive species. Gaillardia aristata (great blanketflower) is planted worldwide and its escape has been reported in several European countries without ecological impact assessment on the invasive potential. As there is a markedly spreading population with invasive behaviour in Hungary, we aimed to reveal the distribution, impacts and traits of G. aristata. We gathered occurrence data outside the gardens in Hungary, based on literature, unpublished observations by experts and our own records. We investigated the impacts of an extended population, where the species invaded sandy old-fields within a 25 km2 area. Here, we compared the species richness, diversity, community composition and height of invaded and uninvaded vegetation. Furthermore, we evaluated the traits potentially associated with the invasiveness of G. aristata in comparison with other herbaceous invasive species in the region. We found that G. aristata occurred mostly by casual escapes, but naturalised and invasive populations were also detected in considerable numbers. G. aristata usually appeared close to gardens and ruderal habitats, but also in semi-natural and natural grasslands and tended to spread better in sandy soils. We found lower plant species richness and Shannon diversity in the invaded sites and the invasion of G. aristata significantly influenced the composition of the plant community. The trait analyses revealed that the invasive potential of G. aristata is backed by a wide germination niche breadth, extremely long flowering period, small shoot-root ratio (large absorption and gripping surface), large seeds (longer persistence) and dispersal by epizoochory of grazing livestock (mostly by sheep), probably helping the species’ survival and spreading in the disturbed, species-poor, sandy, open habitats. These functional traits, as well as the ornamental utilisation, may act together with the aridisation of the climate and the changing land-use practices (e.g. abandoned, disturbed sites) in the success of G. aristata. We raise awareness of the rapid transition of G. aristata from ornamental plant to casual alien and then to invasive species in certain environmental conditions (i.e. sandy soils, species-poor communities, human disturbances), although it seems to be not a strong ecosystem transformer so far. Nonetheless, banning it from seed mixtures, developing eradication strategy and long-term monitoring of this species would be important to halt its spreading in time.
