- Humulus scandens
- Description: This species is a herbaceous annual vine.
- Origin and Worldwide Distribution: It is native to Asia, and has been introduced to Europe and North America as an ornamental plant.
- Potential or Known Impacts: It can colonise areas easily and before native species; this advantage can lead to dense patches which overcrowd and outcompete native species. It may cause allergic reactions as it has allergenic pollen.
- How did it/could it get here? It could be imported as an ornamental species or through contaminated soil.
- Is it found in Ireland or Northern Ireland? Not present in Ireland or Northern Ireland.
- Methods for Prevention: EU-level action includes a ban on sales and any planting or keeping, including in aquaria, as well as rapid eradication of any new populations to avoid the excessively high costs associated with its management later on.
- Current Legislative Position (Listed on 14 August 2019) This species must not intentionally be brought into the Union; kept; bred; transported to, from or within the United Kingdom, unless for the transportation to facilities in the context of eradication; placed on the market; used or exchanged; permitted to reproduce, grown or cultivated; or released into the environment.
