Invasion pathways at a crossroad: policy and research challenges for managing alien species introductions
Open accessAbstract
Parties to the Convention on Biological Diversity have agreed that, by 2020, invasion pathways will be identified, prioritized and managed to prevent the introduction of invasive alien species. The challenges facing this target are examined for six primary invasion pathways: assisted colonization as a deliberate release; escape of pets and aquaria species; parasite and pathogen contaminants of wildlife; stowaways on tourist clothing and equipment; navigation corridors; and transboundary implications of unaided spread. Economic drivers such as tourism, the pet trade and infrastructure projects will accelerate invasive alien species introductions, particularly in emerging economies. Mitigation requires ‘polluter pays’ legislation combined with improved policy enforcement and compliance. Policy implications. Policymakers require new risk analysis tools to predict the hazards posed by species with no prior invasion history, the vulnerability of native biodiversity to emerging diseases, and the components of regional species pools that become invasive following connection via corridors.

Many pet species can establish outside of captivity, especially under future climate scenarios.
“Europe alone contains an estimated 54 million individual ornamental birds, 28 million small mammals, 14 million aquaria fishes, and nine million reptiles owned as pets; many of these species can establish outside of captivity, especially under future climate scenarios (Hulme, 2015).”

Canals have been instrumental in linking once-separated biogeographical regions and facilitating the spread of invasive alien species, with many such corridors expanded to permit larger vessels and new ones proposed for construction.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
