This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
This guide has a section for each species on the EU list of Union concern and the national lists that actually turn up in gardens here: Sosnowsky's and giant hogweed, Himalayan balsam, Japanese knotweed with its mortgage and disposal problem, Canadian goldenrod, raccoon dog, American mink, Spanish slug, signal crayfish, round goby, ragweed, box tree moth and the Asian hornet.
Each section gives identification photographs, why it matters, the control method that works at that point in the season rather than in general, the legal duty and the penalty for ignoring it, and where a sighting is reported. A focused example is "Spanish slug: what reduces them, and what does nothing at all."
How to use it
Use The species that should not be here, and what the law asks of you to compare stable place facts and official facilities. Live opening, access and disruption information should always be confirmed with the operator before travel.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
