Reference excerpt

The list of invasive alien species of Union concern is a regulatory list of invasive animals and plants whose introduction and spread within the European Union are strictly prohibited due to their significant negative impact on the natural environment, economy, or human health. First published in 2016, it has been updated multiple times and it currently consists of 114 species, of which 65 are animals and 49 are plants.

History In 2016, following the EU Regulation 1143/2014 on Invasive Alien Species (IAS), the European Commission published a first list of 37 IAS of Union concern. The list was first updated in 2017 and comprised 49 species. Since the second update in 2019, 66 species are listed as IAS of EU concern. Since the third update in 2022, 88 species are listed as IAS of EU concern, although the final inclusion of three of these species has been deferred to 2024, and one to 2027. Finally, in 2025 further 26 species were added, so the list now contains 114 species.

Regulations The species on the list are subject to restrictions on keeping, importing, selling, breeding and growing. Member States of the European Union must take measures to stop their spread, implement monitoring and preferably eradicate these species. Even countries in which they are already widespread are expected to manage the species to avoid further spread.

Worked examples

Example 1 — a first encounter with List of invasive alien species of Union concern

Start with the simplest possible case. Write down what List of invasive alien species of Union concern claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of invasive alien species of Union concern before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of invasive alien species of Union concern ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of invasive alien species of Union concern

In research: List of invasive alien species of Union concern appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of invasive alien species of Union concern in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of invasive alien species of Union concern is common in secondary-school and first-year university syllabi. It links to neighbouring topics European Union-related lists, European Union and the environment, European Union law, so understanding it makes those chapters shorter.
In everyday life: Look for List of invasive alien species of Union concern outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
