“…Recently, an introduced population has been reported in the Canary Islands by a national press release, although confirmation is still needed. Although the introduction pathway through which this species has appeared in northern Spain remains unknown, it is likely the result of an intentional release or escape of animals kept in captivity (Oficialdegui et al., 2023 ). Indeed, although the marbled crayfish sale has been restricted, it can be found in pet trade, which has been considered as its main introduction pathway in other countries (Faulkes, 2010 ; Lipták et al., 2023 ).…”

“…1143/2014). Additionally, it was classified as a high‐risk species according to the Freshwater Invertebrate Invasiveness Scoring Kit (Chucholl, 2016 ) and ranked among the top 10 invasive alien species listed in the Alert List during a recent horizon scan exercise for Iberian waters (Oficialdegui et al., 2023 ). However, on account of its later description, it was not included in the Spanish Catalogue of Invasive Alien Species (Royal Decree 630/2013).…”

An eco‐monitoring programme to assess faunal biodiversity in the main rivers of the northern Iberian Peninsula (Spain) reveals the first occurrence of the marbled crayfish Procambarus virginalis (Decapoda: Cambaridae) in Iberian inland waters. Iberian specimens have been identified by combining morphological and genetic traits. We discuss the most plausible pathways and introduction vectors, its potential invasiveness and subsequent impacts on host localities. Our preliminary results raise concern about the potential threat of P. virginalis to native fauna and ecosystem dynamics, as P. virginalis was found in an area of great cultural and ecological importance with relevant populations of endangered species. Due to the invasive history of the marbled crayfish, eradication of these individuals is urgent. This study confirms the importance of early warning systems for exotic species, keeping the population, forest guards and field technicians informed about potential invasive species to execute a rapid and effective response.

“…First, Ponto‐Caspian MS are the main donors of freshwater NPIS in other MS, especially in southern countries (e.g., Italy, Spain, and Portugal), which have experienced most invasions, although their native species have hardly become invasive elsewhere in the EU. Recent studies highlight the alarming amount of non‐native freshwater fauna in southern countries and how the Union List is insufficient to tackle them (Muñoz‐Mas & García‐Berthou, 2020; Oficialdegui et al., 2023). It is well known that the growing network of inland waterways connecting river basins has long facilitated the range expansion of many freshwater macroinvertebrates and fish species from eastern to western Europe (Leuven et al., 2009).…”

The European Union's (EU) environmental legislation establishes common measures to prevent the entry and spread of invasive non‐native species and to minimize their impacts. However, species that are native to at least 1 member state but non‐native and potentially invasive in others (NPIS) are in limbo because they are neither legally regulated at the EU level nor in most member states. We used the Communication and Information Resource Centre for Administrations, Businesses and Citizens (CIRCABC) raw data on NPISs (317 taxa) to analyze their distribution across the EU and identify which biogeographical regions are the main sources of invasions. We additionally evaluated the conservation challenge posed by NPISs that are threatened in within their native ranges. We performed a pairwise analysis summarizing the number of species that are native to a given member state but non‐native to another and vice versa. While distribution patterns of NPISs varied across taxa groups, overall, southern and central EU countries were both donors and recipients of NPISs. Eastern countries were mainly a source, and western and northern countries mostly received NPISs . Around 27 % of NPISs were threatened in some of their EU native ranges, which is a challenge for conservation and management because some of them have serious negative effects on European biodiversity, but hitherto remain outside the scope of the EU regulation of invasive non‐native species. This highlights an unresolved paradox because efforts to manage species as invasive conflict with efforts to protect them as threatened within the same territory.This article is protected by copyright.

“…Horizon scanning is rising in popularity internationally as a method for identifying invasive species threats and their pathways for arrival and is recognized as an important part of invasive species management (e.g., Gallardo et al, 2016; Kenis et al, 2022; Lucy et al, 2020; Oficialdegui et al, 2023; Roy et al, 2015). These efforts produce evidence‐based lists of potential invaders to inform development of precautionary measures and management before an invader is introduced (Roy et al, 2014).…”

Managing invasive species with prevention and early‐detection strategies can avert severe ecological and economic impacts. Horizon scanning, an evidence‐based process combining risk screening and consensus building to identify threats, has become a valuable tool for prioritizing invasive species management and prevention. We assembled a working group of experts from academic, government, and nonprofit agencies and organizations, and conducted a multi‐taxa horizon scan for Florida, USA, the first of its kind in North America. Our primary objectives were to identify high‐risk species and their introduction pathways, to detail the magnitude and mechanism of potential impacts, and, more broadly, to demonstrate the utility of horizon scanning. As a means to facilitate future horizon scans, we document the process used to generate the list of taxa for screening. We evaluated 460 taxa for their potential to arrive, establish, and cause negative ecological and socioeconomic impacts, and identified 40 potential invaders, including alewife, zebra mussel, crab‐eating macaque, and red swamp crayfish. Vertebrates and aquatic invertebrates posed the greatest invasion threat, over half of the high‐risk taxa were omnivores, and there was high confidence in the scoring of high‐risk taxa. Common arrival pathways were ballast water, biofouling of vessels, and escape from the pet/aquarium/horticulture trade. Competition, predation, and damage to agriculture/forestry/aquaculture were common impact mechanisms. We recommend full risk analysis for the high‐risk taxa; increased surveillance at Florida's ports, state borders, and high‐risk pathways; and periodic review and revision of the list. Few horizon scans detail the comprehensive methodology (including list‐building), certainty estimates for all scoring categories and the final score, detailed pathways, and the magnitude and mechanism of impact. Providing this information can further inform prevention efforts and can be efficiently replicated in other regions. Moreover, harmonizing methodology can facilitate data sharing and enhance interpretation of results for stakeholders and the general public.
