Non-native species
There are several thousand non-native species in the UK. A minority pose serious ecological or economic threats and are described as invasive non-native species. For example, Japanese knotweed causes problems for the construction and transport infrastructure sectors.
New species are being introduced to Europe, for example through trade, horticulture, landscaping, transport of goods, etc. There is a risk of introducing new invasive species that will become problems in the future.

New Legislation relating to invasive species
The Invasive Alien Species (Enforcement and Permitting) Order (Northern Ireland) 2019 (“the Enforcement Order”) came into force on 1 December 2019.
This relates to The Regulation (EU) No. 1143/2014 on the prevention and management of the introduction and spread of invasive alien species ("the Principal Regulation") which came into force on 1 January 2015.
It imposes strict restrictions on a list of species known as ‘species of Union concern’. These are species whose potential adverse impacts across the European Union are such that concerted action across Europe is required.
The restrictions mean that (subject to certain defences, or exemptions through permits or licences) species of Union concern cannot be imported into the EU, kept, bred, transported, placed on the market, used or exchanged, allowed to reproduce, grown or cultivated, or released into the environment.
