Measures against the spread of invasive alien species
Measures against the spread of invasive alien species
What's at stake: The question concerns how effectively Sweden can stop new invasive species at the border and at sea before they establish themselves and damage native ecosystems, agriculture, and aquatic environments.
Case texts and AI reasoning are AI-translated from the Swedish originals; the Swedish text is authoritative.
What the vote decides
Parliament decides whether current and already-adopted measures against invasive alien species are sufficient, or whether the framework should be followed up and expanded, including clearer inter-agency cooperation at border controls and protection against spread in the marine environment.
Yes Yes — the committee proposal
The committee rejects the motions, noting that the government has already intensified work against invasive alien species — including strengthened national coordination, more control measures, and communication efforts — and that the proposed legal changes will strengthen the framework ahead of a national list of invasive species.
No No — the reservations
Reservation 1 (C)
Reservation (the Centre Party): the framework should be followed up once in force, authorities should review how they can assist Customs at border controls, and the framework should be developed to better protect against the spread of invasive species in the marine environment, e.g. via ship hulls (biofouling).
Summarised from the committee report. Party labels in the summary come from the report, not from the vote.
What do the votes mean here?
Yes The committee proposal: rejecting the motions (keeping things as they are).
No Backing the counter-proposal: reservation 1 by C.
Abstain The party marks a position of its own that is not one of the two final alternatives.
The decision would have held
Explicit commitments that contradicted the vote: SDSverigedemokraterna
Ja 259–21Ja 198–82
Counterfactual: the parties above are moved to the position their own documents explicitly point at, carrying their whole contingent present. Every other party keeps its real figures, including dissenters and absentees.
How the AI parties would have voted
For each party: what its own plan – election manifesto and party programme – argues for in this case, next to how the party actually voted. The AI can only answer Yes or No; a party can also abstain.

Riksdag decision: The Riksdag approved the government's proposal to tighten the regulations for invasive alien species. The bill means, among other things, that a person who intentionally or through gross negligence introduces an invasive alien species to Sweden from another EU country can be sentenced to fines or imprisonment for up to two years. The proposal also means that a person who introduces invasive alien species from another EU country must be obliged to report the species to the Swedish Customs Agency. The Customs Agency must also be granted authority to check the importation of foreign species at the internal land border and, if necessary, seize such species. Invasive alien species means species of animals, plants, fungi or microorganisms that are introduced and spread in the environment and cause problems for, for example, native plants and animals, human health and society. The law changes enter into force on 1 May 2026. The Riksdag also rejected approximately 200 proposals in motions from the ordinary motion period 2025, primarily citing measures already taken. The proposals concern, among other things, invasive alien species, area protection, species protection, remediation and shore protection.
Counter-proposals
- The counter-proposal wants a follow-up of the stricter regulations, assistance to Customs in controlling invasive species from other authorities, and strengthened coordination between county administrative boards. (C) — Reservation 1
Plan vs actual vote
Every party, in chamber order: what its own plan pointed to, how it voted, and the reasoning behind both. Highlighted rows are where the two differ — but a vote that follows the plan is a result too, so the reasoning is there for every party.
The plan warns that overexploitation of nature depletes biodiversity and demands conscious and comprehensive work for good conditions for ecosystems.
Plan documents: party programme · 2022 manifesto
Reasoning and quotes
The plan warns that overexploitation of nature depletes biodiversity and demands conscious and comprehensive work for good conditions for ecosystems. It wants environmental goals followed up with strict legislation and practical work. Monitoring of regulations, support for border control and protection against spread of invasive species in the marine environment is such practical implementation.
Original (Swedish)
Planen varnar för att överutnyttjandet av naturen utarmar den biologiska mångfalden och kräver ett medvetet och heltäckande arbete för goda villkor för ekosystemen. Den vill ha miljömål som följs upp med skarp lagstiftning och praktiskt arbete. Uppföljning av regelverket, stöd till gränskontrollen och skydd mot spridning av invasiva arter i havsmiljön är sådant praktiskt genomförande.

- monitoring of environmental rules»miljömål som följs upp med skarp lagstiftning och praktiskt arbete.« (party programme ↗)“environmental goals followed up with strict legislation and practical work.”
The plan takes no explicit position on what the committee actually decided — often because the committee's reason was procedural. The stance is derived and fully cited, but it does not show the party broke a commitment.
The plan requires protection of biological diversity and Sweden's aquatic environments and particularly points out the Baltic Sea as a sea in crisis, which supports the counter-proposal's demands for developed protection against the spread of invasive species in marine environments.
Plan documents: party programme · 2022 manifesto
Reasoning and quotes
The plan requires protection of biological diversity and Sweden's aquatic environments and particularly points out the Baltic Sea as a sea in crisis, which supports the counter-proposal's demands for developed protection against the spread of invasive species in marine environments. Monitoring of regulations and support for border control follow from the requirement that society have control where the harmful effects are cross-border. Invasive species are not treated explicitly in the documents.
Original (Swedish)
Planen kräver värn av biologisk mångfald och av Sveriges vattenmiljöer och pekar särskilt ut Östersjön som ett hav i kris, vilket bär motförslagets krav på utvecklat skydd mot spridning av invasiva arter i havsmiljön. Uppföljning av regelverket och stöd till gränskontrollen följer av att samhället ska ha kontroll där skadeverkningarna är gränsöverskridande. Invasiva arter behandlas inte uttryckligen i dokumenten.

The plan makes protection of biodiversity a core commitment: nature should be protected, strengthened and restored, and Sweden should actively work against trade that threatens species.
Plan documents: party programme
Reasoning and quotes
The plan makes protection of biodiversity a core commitment: nature should be protected, strengthened and restored, and Sweden should actively work against trade that threatens species. Following up on regulations, support for border control and protection against spread via ship hulls are measures in that direction. The plan also requires that protection of marine areas and ecosystems be expanded and strengthened.
Original (Swedish)
Planen gör skyddet av den biologiska mångfalden till ett kärnåtagande: naturen ska skyddas, stärkas och återställas, och Sverige ska arbeta aktivt mot handel som hotar arter. Uppföljning av regelverket, stöd till gränskontrollen och skydd mot spridning via fartygsskrov är åtgärder i den riktningen. Planen kräver dessutom att skyddet av marina områden och ekosystem utökas och stärks.

The plan explicitly states that more must be done to combat invasive species as part of caring for nature and developing biological diversity.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The plan explicitly states that more must be done to combat invasive species as part of caring for nature and developing biological diversity. It also wants to save lakes, watercourses and seas. Follow-up of regulations, support for border control and enhanced protection in the marine environment are measures that serve exactly this.
Original (Swedish)
Planen säger uttryckligen att mer måste göras för att bekämpa invasiva arter som en del av att vårda naturen och utveckla den biologiska mångfalden. Den vill också rädda sjöar, vattendrag och hav. Uppföljning av regelverket, stöd till gränskontrollen och ett utvecklat skydd i havsmiljön är åtgärder som tjänar just detta.
- combat invasive speciesdecisive»Sveriges natur ska vårdas och den biologiska mångfalden utvecklas. Mer måste göras för att restaurera våtmarker, bekämpa invasiva arter och underlätta för markägare att bidra, då frivillighet och äganderätt är grunden för en bättre naturvård.« (2022 manifesto ↗)“Sweden's nature shall be cared for and biological diversity developed. More must be done to restore wetlands, combat invasive species and facilitate landowners to contribute, as voluntary participation and ownership are the foundation for better nature conservation.”

The plan demands that the seas are protected through agreements between coastal states with clear sanctions for breaches, and that threatened species are protected through preservation and habitat protection.
Plan documents: party programme · 2022 manifesto
Reasoning and quotes
The plan demands that the seas are protected through agreements between coastal states with clear sanctions for breaches, and that threatened species are protected through preservation and habitat protection. Monitoring of the regulations and protection against spreading of invasive species via ship hulls lies directly in that work. The plan also wants to give nature conservation a renaissance.
Original (Swedish)
Planen kräver att haven skyddas genom avtal mellan kuststaterna med tydliga sanktioner vid överträdelser, och att hotade arter skyddas genom fridlysning och biotopskydd. Uppföljning av regelverket och skydd mot spridning av invasiva arter via fartygsskrov ligger direkt i det arbetet. Planen vill dessutom ge naturvården en renässans.

The plan states that biological diversity is important for many reasons and a prerequisite for ecosystems' long-term productive capacity, which bears the requirement for developed protection against spread of invasive species.
Plan documents: party programme
Reasoning and quotes
The plan states that biological diversity is important for many reasons and a prerequisite for ecosystems' long-term productive capacity, which bears the requirement for developed protection against spread of invasive species. The precautionary principle requires extra caution in suspicion of irreversible environmental damage, which motivates monitoring of the regulatory framework and protection in the marine environment. That the most serious environmental threats are transboundary supports the requirement that authorities assist border control.
Original (Swedish)
Planen slår fast att den biologiska mångfalden är viktig av många skäl och en förutsättning för ekosystemens långsiktiga produktionsförmåga, vilket bär kravet på ett utvecklat skydd mot spridning av invasiva arter. Försiktighetsprincipen kräver extra försiktighet vid misstanke om oåterkallelig skada på miljön, vilket motiverar uppföljning av regelverket och skydd i havsmiljön. Att de allvarligaste miljöhoten är gränsöverskridande stöder kravet på att myndigheter bistår gränskontrollen.
- protect biological diversitydecisive»Att slå vakt om den biologiska mångfalden är viktigt av många skäl.« (party programme ↗)“To stand guard over biological diversity is important for many reasons.”
- precautionary principle»skada på miljön, måste extra försiktighet tillämpas.« (party programme ↗)“damage to the environment, extra caution must be applied.”
- transboundary environmental threats»De allvarligaste miljöhoten är globala eller storregionala.« (party programme ↗)“The most serious environmental threats are global or large-regional.”
- active preservation work»Bevarande av den biologiska mångfalden kräver både reservatsskydd i olika former och stor« (party programme ↗)“Preservation of biological diversity requires both reserve protection in various forms and great”

The plan commits to strengthening joint Baltic work and protecting the marine environment, and it wants to give customs more resources and powerful authorities at the border.
Plan documents: 2022 manifesto
Reasoning and quotes
The plan commits to strengthening joint Baltic work and protecting the marine environment, and it wants to give customs more resources and powerful authorities at the border. Following up the regulations, strengthening border control support and developing protection against spread through hull fouling is in that direction. Invasive species are not mentioned in the plan, so the support is derived.
Original (Swedish)
Planen åtar sig att förstärka det gemensamma Östersjöarbetet och att skydda havsmiljön, och den vill ge tullen mer resurser och kraftfulla befogenheter vid gränsen. Att följa upp regelverket, stärka gränskontrollens stöd och utveckla skyddet mot spridning via fartygsskrov ligger i den riktningen. Invasiva arter nämns dock inte i planen, varför stödet härleds.

The counter-proposal wants to follow up the regulations against invasive alien species, strengthen border control support and develop protection of the marine environment.
Plan documents: 2022 manifesto
Reasoning and quotes
The counter-proposal wants to follow up the regulations against invasive alien species, strengthen border control support and develop protection of the marine environment. The election manifesto explicitly establishes that more must be done to prevent and solve problems with invasive plant and animal species and that the marine environment should be prioritised. The demand is therefore directly in the plan's commitment.
Original (Swedish)
Motförslaget vill följa upp regelverket mot invasiva främmande arter, stärka gränskontrollens stöd och utveckla skyddet i havsmiljön. Valmanifestet slår uttryckligen fast att mer måste göras för att förebygga och lösa problemen med invasiva växt- och djurarter och att havsmiljön ska prioriteras. Kravet ligger därmed direkt i planens åtagande.
