“…While some of them do not have any evident impact in the newly colonized areas, others may become invasive, rapidly expanding their area and imposing severe pressure on the invaded area's ecosystems both from an economic and an ecological point of view. The chance of a non-native species becoming invasive strongly depends on the suitability of the environmental conditions including availability of host plants (Csóka et al 2019;Paulin et al 2020), effects of native natural enemies (Csóka et al 2009;Panzavolta et al 2018;Kos et al 2020). The weather and climate may also be decisive factors from the point of the establishment and the future of the established populations.…”

“…The North American oak lace bug (Corythucha arcuata (Say 1832) -Heteroptera: Tingidae) is a recent invader in Europe, first discovered in Italy in 2000 (Bernardinelli et al 2000). In the last decade, it showed an explosive area expansion and has been reported from 20 European countries (Paulin et al 2020). As almost all native deciduous oaks are suitable hosts for the oak lace bug (OLB), at least 30 million hectares of oak for-ests provide acceptable hosts for it in Europe (Csóka et al 2019).…”

“…As almost all native deciduous oaks are suitable hosts for the oak lace bug (OLB), at least 30 million hectares of oak for-ests provide acceptable hosts for it in Europe (Csóka et al 2019). Although there are major gaps in knowledge concerning the further spread and damage of the OLB, it seems potentially very dangerous both from an economic and an ecological point of view (Nikolic et al 2019;Csóka et al 2019;Paulin et al 2020).…”

The North American oak lace bug (Corythucha arcuata) was first discovered in Europe (Norhern Italy) in 2000. It started a rapid area expansion in the last decade and has been reported in 20 countries so far. Almost all European oaks are suitable hosts. On top of the host availability, abiotic factors like weather/climate may also have a decisive impact on its further spread and future outbreaks. We conducted a simple field survey within three years, at five locations to estimate the overwintering mortality of the species. Our results suggest that not even a relatively harsh winter (as 2016/2017) caused severe mortality in the overwintering populations. The average mortality of the nine year/location combinations was 30.6% (range 9.1–58.5%). Based on this, the low winter temperature is unlikely to restrict its further spread, therefore continuing area expansion can be predicted.

“…For example, the fruit and nut breeding Nearctic insect Chymomyza amoena was assigned to the lowest impact category Minor concern (MC), because no negative impact on native host species was observed despite its rapid spread since its arrival to Europe in 1975. However, the impact classification of alien insects may increase in time, if more research on other mechanisms is conducted like the competition with native species, which was recently discussed by Paulin et al (2020) for North American oak lace bug (Corythucha arcuata). The feeding by C. arcuata can lead to a shortage of food for specialized oak-associated species and can cause larger negative impacts than previously expected (Paulin et al 2020).…”

The prioritization of alien species according to the magnitude of their environmental impacts has become increasingly important for the management of invasive alien species. In this study, we applied the Environmental Impact Classification of Alien Taxa (EICAT) to classify alien taxa from three different taxonomic groups to facilitate the prioritisation of management actions for the threatened riparian forests of the Mura-Drava-Danube Biosphere Reserve, South East Europe. With local experts we collated a list of 198 alien species (115 plants, 45 insects, and 38 fungi) with populations reported in southeast European forest ecosystems and included them in the EICAT. We found impact reports for 114 species. Eleven of these species caused local extinctions of a native species, 35 led to a population decrease, 51 to a reduction in performance in at least one native species and for 17 alien species no effects on individual fitness of native species were detected. Fungi had significantly highest impact and were more likely to have information on their impacts reported. Competition and parasitism were the most important impact mechanisms of alien species. This study is, to our knowledge, the first application of EICAT to all known alien species of several taxonomic groups in a protected area. The impact rankings enabled to identify taxa that generally cause high impacts and to prioritize species for the management in protected areas according to their impact magnitudes. By following a standardized impact protocol, we identified several alien species causing high impacts that do not appear on any expert-based risk list, which are relevant for policymakers. Thus, we recommend that alien species be systematically screened to identify knowledge gaps and prioritize their management with respect to spatio-temporal trends in impact magnitudes.

Where to search: the use of opportunistic data for the detection of an invasive forest pest

Early detection is important for the management of invasive alien species. In the last decade citizen science has become an important source of such data. Here, we used opportunistic records from the “LIFE ARTEMIS” citizen science project, in which people submitted records from places where they observed tree pests, to understand the distribution of a rapidly-spreading forest pest: the oak lace bug (Corythucha arcuata) in Slovenia. These citizen science records were not distributed randomly. We constructed a species distribution model for C. arcuata that accounted for the biased distribution of citizen science by using the records of other tree pests and diseases from the same project as pseudo-absences (so-called constrained pseudo-absences), and compared this to a model with pseudo-absences selected randomly from across Slovenia. We found that the constrained pseudo-absence model showed that C. arcuata was more likely to be found in east, in places with more oak trees and at lower elevations, and also closer to highways and railways, indicating introduction and dispersal by accidental human transport. The outputs from the model with random pseudo-absences were broadly similar, although estimates from this model tended to be higher and less precise, and some factors that were significant (proximity to minor roads and human settlements) were artefacts of recorder bias, showing the importance of taking the distribution of recording into account wherever possible. The finding that C. arcuata is more likely to be found near highways allows us to design advice for where future citizen science should be directed for efficient early detection.
