“…resulted in a high percentage of cost entries reported in Spanish (98%), consistent with findings in some other European countries that reported costs in their native language (e.g. 97% for France, Renault et al 2021; 69% for Germany, Haubrock et al 2021b). For instance, in Central and South America over 40% of cost estimates came from Spanish and Portuguese sources (Heringer et al 2021); and in Ecuador 51.8% of the costs were reported in Spanish (Ballesteros-Mejia et al 2021).…”

“…This species, together with D. polymorpha or Neovison vison, which are amongst the ten costliest species in Spain, are also amongst the invasive aquatic species causing the most widespread economic impacts (Cuthbert et al 2021a). E. crassipes also seems to be one of the costliest species in several African countries, in Asia and in North American countries, such as Mexico (Diagne et al 2021b;Liu et al 2021;Rico-Sánchez 2021); while D. polymorpha seems to be very costly in the USA and N. vison in other European countries such as Germany (Crystal-Ornelas et al 2021;Haubrock et al 2021b). Being in the list of the 100 of the worst invasive species, D. polymorpha was also ranked as the 8 th costliest species of that list (Cuthbert et al 2021b).…”

Economic assessments for invasive alien species (IAS) are an urgent requirement for informed decision-making, coordinating and motivating the allocation of economic and human resources for the management of IAS. We searched for economic costs of IAS occurring in Spain, by using the InvaCost database and requesting data to regional governments and national authorities, which resulted in over 3,000 cost entries. Considering only robust data (i.e. excluding extrapolated, potential (not-incurred or expected) and low reliability costs), economic costs in Spain were estimated at US$ 261 million (€ 232 million) from 1997 to 2022. There was an increase from US$ 4 million per year before 2000 to US$ 15 million per year in the last years (from € 4 to 13 million). Robust data showed that most reported costs of IAS in Spain (> 90%) corresponded to management costs, while damage costs were only found for 2 out of the 174 species with reported costs. Economic costs relied mostly on regional and inter-regional administrations that spent 66% of costs in post-invasion management actions, contrary to all international guidelines, which recommend investing more in prevention. Regional administrations unequally reported costs. Moreover, 36% of the invasive species, reported to incur management costs, were not included in national or European regulations (i.e. Black Lists), suggesting the need to review these policies; besides, neighbouring regions seem to manage different groups of species. We suggest the need of a national lead agency to effectively coordinate actions, facilitate communication and collaboration amongst regional governments, national agencies and neighbouring countries. This will motivate the continuity of long-lasting management actions and the increase in efforts to report IAS costs by regional and inter-regional managers which will adequately provide information for future budgets gaining management effectiveness.

“…Kettunen et al (2009) reported total annual costs of IAS of ~€12 billion across Europe, although given the scarcity of data available at this time, sources and methods used were generally scant (Bradshaw et al 2016;Diagne et al 2020aDiagne et al , 2020b. Other publications have attempted to collectively assess the costs of IAS (Hoffmann and Broadhurst 2016), for different organism types (Lovell et al 2006;Van der Veer and Nentwig 2015;Bradshaw et al 2016;Barbet-Massin et al 2020;Cuthbert et al 2021b), and for different countries (e.g. Great Britain: Williams et al 2010).…”

Biological invasions continue to threaten the stability of ecosystems and societies that are dependent on their services. Whilst the ecological impacts of invasive alien species (IAS) have been widely reported in recent decades, there remains a paucity of information concerning their economic impacts. Europe has strong trade and transport links with the rest of the world, facilitating hundreds of IAS incursions, and largely centralised decision-making frameworks. The present study is the first comprehensive and detailed effort that quantifies the costs of IAS collectively across European countries and examines temporal trends in these data. In addition, the distributions of costs across countries, socioeconomic sectors and taxonomic groups are examined, as are socio-economic correlates of management and damage costs. Total costs of IAS in Europe summed to US$140.20 billion (or €116.61 billion) between 1960 and 2020, with the majority (60%) being damage-related and impacting multiple sectors. Costs were also geographically widespread but dominated by impacts in large western and central European countries, i.e. the UK, Spain, France, and Germany. Human population size, land area, GDP, and tourism were significant predictors of invasion costs, with management costs additionally predicted by numbers of introduced species, research effort and trade. Temporally, invasion costs have increased exponentially through time, with up to US$23.58 billion (€19.64 billion) in 2013, and US$139.56 billion (€116.24 billion) in impacts extrapolated in 2020. Importantly, although these costs are substantial, there remain knowledge gaps on several geographic and taxonomic scales, indicating that these costs are severely underestimated. We, thus, urge increased and improved cost reporting for economic impacts of IAS and coordinated international action to prevent further spread and mitigate impacts of IAS populations.

“…Similarly, the cost of invasive alien plants to the Australian economy within agricultural areas alone is estimated at US$ 4 billion annually (Sinden et al 2005), and aquatic invasive alien plants in 13 public lakes in Florida cause annual costs of US$ 6 billion (Adams and Lee 2007). Plants also feature prominently among the world's "100 of the worst" invasive alien species (Boudjelas et al 2000), of which Euphorbia esula (Euphorbiaceae) ranks among the top ten economically most damaging species with a global cost of US$ 7.3 billion between 1960 and 2020 (Cuthbert et al 2021). This selection of studies alone -which is by no means exhaustive -illustrates that the real costs of plant invasions globally must be orders of magnitude higher than the US$8.9 billion estimate reported by Diagne et al (2021).…”
