“…Our findings reveal an important disparity between the spatial distribution of invasive species and the most vulnerable areas in terms of ecosystem service provisioning, particularly for regulating and cultural services. This observation aligns with previous studies highlighting the highest density of invasive species and their impacts in urban, cropland, and grassland ecosystems in Europe 23 , as well as at the global scale 15 . Indeed, it is well-established that human-altered habitats are especially susceptible to invasions due to their elevated levels of disturbance and propagule pressure 14 , but see 16 .…”

“…Vulnerability is determined by the level of provisioning of ecosystem services that are known to be susceptible to each invader, with both very high and very low provisioning areas considered vulnerable to biological invasions 13 . For instance, human-altered habitats are highly exposed to invasions because of their high levels of disturbance and propagule pressure 14 , 15 . This is frequently the case for invasive plants, whereas invasive animals tend to be more evenly distributed in natural and human-altered environments 15 , 16 .…”

Invasive species significantly impact biodiversity and ecosystem services, yet understanding these effects at large spatial scales remains a challenge. Our study addresses this gap by assessing the current and potential future risks posed by 94 invasive species to seven key ecosystem services in Europe. We demonstrate widespread potential impacts, particularly on outdoor recreation, habitat maintenance, crop provisioning, and soil and nitrogen retention. Exposure to invasive species was higher in areas with lower provision of ecosystem services, particularly for regulating and cultural services. Exposure was also high in areas where ecosystem contributions to crop provision and nitrogen retention were at their highest. Notably, regions vital for ecosystem services currently have low invasion suitability, but face an average 77% increase in potential invasion area. Here we show that, while high-value ecosystem service areas at the highest risk represent a small fraction of Europe (0-13%), they are disproportionally important for service conservation. Our study underscores the importance of monitoring and protecting these hotspots to align management strategies with international biodiversity targets, considering both invasion vulnerability and ecosystem service sustainability.

“…The associated ecological and economic costs make alien species management an urgent task (Pyšek et al 2020). Estimations and projections of current and future distributions are important for alien species management, especially as their spread will certainly be affected by other drivers of global change, such as climate and land‐use change (Bellard et al 2015, Vilà and Hulme 2017, Northrup et al 2019, Liu et al 2023). These changes alter both biotic and abiotic ecosystem properties known to be critical for biological invasions (Rodríguez‐Labajos et al 2009, Bellard et al 2016, Dullinger et al 2017).…”

Alien species can have massive impacts on native biodiversity, ecosystem functioning, and human livelihoods. Assessing which species from currently cultivated alien floras may escape into the wild and naturalize is essential for efficient and proactive ecosystem management and biodiversity conservation. Climate change has already promoted the naturalization of many alien plants in temperate regions, but whether it is similar in (sub)tropical areas is insufficiently known. In this study, we used species distribution models for 1527 cultivated alien plants to evaluate current and future invasion risks across different biomes and 10 countries in southern Africa. Our results confirm that the area of suitable climate is a strong predictor of naturalization success among the cultivated alien flora. In contrast to previous findings from temperate regions, however, climatic suitability is generally predicted to decrease for potential aliens across our (sub)tropical study region. While increasingly hotter and drier conditions are likely to drive declines in suitability for potential aliens across most biomes of southern Africa, in some the number of potential invaders is predicted to increase under moderate climate change scenarios (e.g. in dry broadleaf forests and flooded grasslands). We found that climatic suitability is expected to decline less for aliens originating from continents with the tropical biome or from the Southern Hemisphere. In addition, we found that the climatically suitable area will decline less for aliens that have already naturalized in the region. While the number of potential invaders may decrease across southern Africa under future climate change, our results suggest that already naturalized aliens will continue to threaten native species and ecosystems.

“…Not only do the species‐environment relationships vary across scales but the relative importance of environmental conditions facilitating invasions becomes more apparent when assessed over diverse land use, management regimes and biogeography (Kotowska et al, 2022). While every invasive plant might have a suit of drivers, some key components of the ecosystems like habitat fragmentation, hydrological alterations and proximity to human land use can facilitate invasions (Liu et al, 2023). Evidence for this could help in controlling the drivers that facilitate invasions and reinforce drivers that resists invasions.…”

Biological invasions threaten biodiversity and human wellbeing, with developing tropical countries being more vulnerable. Despite the urgency to reduce impacts of invasions, management interventions are constrained by unavailability of timely information on invasive species occurrence, potential drivers and restoration priorities. Generating this information at biogeographic scales can be costly, unless integrated with multi‐objective biodiversity monitoring. Invasive plant monitoring is integrated with India's national‐scale tiger population assessment, wherein natural areas are sampled at 25 km2 scale to inventory plants. In 2018, a total of 158,979 plots were sampled covering ~358,550 km2. We used 206,393 locations of high concern invasive plants to model their distribution using socio‐ecological covariates and identify potential drivers of invasions. Considering the invasion magnitude and financial constraints in management, we further identified priority restorations sites at national‐scale to maximise biodiversity outcomes. High‐concern invasive plants were recorded from ~254,880 km2 (72% sampled area) and modelled to invade in total ~750,905 km2 (66%) Indian natural systems. While open and deciduous ecosystems were the highest invaded by woody plants, areas with extreme climate and less anthropic pressure were least invaded. Since managing invasions across their range seemed futile due to costly (~13.5 billion USD for one‐time management) and ineffective strategies, restoration priority was assigned to least invaded areas (11% protected areas, 23% multi‐use) to maximise biodiversity returns. Synthesis and applications: India implemented national‐scale invasive plant monitoring by integrating it with the umbrella project on tiger assessment. Embarking on this big data, we show that two‐thirds of India's natural areas are under multiple plant invasions, owing to the legacy of anthropogenic modifications. Our study offers a restoration priority model, empowering policymakers to devise adaptive strategies for restoring invaded biomes and maximizing biodiversity returns.
