“…Currently, global impact assessments (e.g. EICAT) are lacking for most taxa and, at the regional level, country-specific assessments of impact mechanisms and magnitudes are not systematically assessed and reported (although see [14]). The indicators presented here can be expressed at any spatial grain for which species occurrence and impact evidence exist.…”

“…It is likely that available impact evidence relevant for these indicators will grow, including, for example, EICAT assessments for new taxa (e.g. [ 14 ]), regional impact evidence (countries and islands) from GRIIS [ 24 ], information on socioeconomic impacts (e.g. [ 44 ]) and more sophisticated estimates of compound and synergistic impacts (e.g.…”

“…Individual IAS commonly have multiple mechanisms and types of impact (e.g. [ 14 , 15 ]), and particular areas are increasingly exposed to impacts from multiple species [ 16 ]. It is also crucial that the location and timing of impact events are comprehensively recorded [ 7 ].…”

“…Indeed, a dearth of environmental impact knowledge has constrained the usefulness of using EICAT as an impact indicator across taxa and in many countries (but see [ 20 , 23 ]). For example, there are inadequate data to assess the impacts of two thirds of invasive alien insects [ 14 ]. Identifying and addressing information shortfalls are an essential step towards ensuring that IAS monitoring is overseen by robust decision-making [ 7 ].…”

Monitoring the extent to which invasive alien species (IAS) negatively impact the environment is crucial for understanding and mitigating biological invasions. Indeed, such information is vital for achieving Target 6 of the Kunming–Montreal Global Biodiversity Framework. However, to-date indicators for tracking the environmental impacts of IAS have been either lacking or insufficient. Capitalizing on advances in data availability and impact assessment protocols, we developed environmental impact indicators to track realized and potential impacts of IAS. We also developed an information status indicator to assess the adequacy of the data underlying the impact indicators. We used data on 75 naturalized amphibians from 82 countries to demonstrate the indicators at a global scale. The information status indicator shows variation in the reliability of the data and highlights areas where absence of impact should be interpreted with caution. Impact indicators show that growth in potential impacts are dominated by predatory species, while potential impacts from both predation and disease transmission are distributed worldwide. Using open access data, the indicators are reproducible and adaptable across scales and taxa and can be used to assess global trends and distributions of IAS, assisting authorities in prioritizing control efforts and identifying areas at risk of future invasions. This article is part of the theme issue ‘Ecological novelty and planetary stewardship: biodiversity dynamics in a transforming biosphere’.

Alien species invasion and habitat destruction are among the primary threats to native animal communities, particularly for native predator–prey systems. However, when predator invasion and habitat destruction co‐occur, it remains unclear whether their respective threats to native systems compensate each other or accumulate, as well as how these effects respond to the different characteristics of predator invasion and habitat destruction. In this study, we developed a spatially explicit simulation model with one prey species and one predator species and exposed it to invasive predators and habitat destruction with different properties. The results revealed the following insights: (1) Habitat destruction can compensate threats to native predator–prey systems from global predator invasion only when native predators possess predation capability similar to those of the invaders. In other scenarios, cumulative effects arise from predator invasion and habitat destruction. (2) Low levels of habitat destruction occurring at a faster rate, in conjunction with a substantial number of global invasive predators being present, can better compensate their respective threats to native predator–prey systems than the other scenarios. These findings provide valuable insights into situations where habitat destruction and alien species invasion coincide. They raise the question of whether we can leverage the interaction between them to reduce threats to biodiversity.
