Invasive, non native species

Invasive, non-native species are plants and animals that do not naturally live in Scotland and can cause harm to the environment. They spread quickly, damage habitats, block rivers, and can affect buildings and people’s health. If you spot one, you can help by reporting it and stopping it from spreading.

What you need to know

These species can take over areas and push out native plants and wildlife. Once established, they are difficult and costly to remove. Common examples include Japanese knotweed and North American signal crayfish.

We all have a role in preventing their spread by recognising them and taking action.

How to identify and report a species

You can identify species and check where they have been found using the Non-native Species Secretariat website. If you are unsure, you can contact us for help.

When reporting a sighting, please include:

• clear photos of the plant or animal (including leaves and stems)
• a location (use a grid reference or What3Words if possible)

You can also report sightings to:

• SEWeb for most species
• Network Rail if seen along railway lines
• the relevant body for trunk roads and motorways

To report a species on council land, use our Waste and Grounds services enquiry form.

Landowner responsibilities

If you see invasive species on private land, you may wish to inform the landowner. Landowners must not allow these species to spread into the wild or neighbouring properties.

You can find guidance on control methods and legal responsibilities on the NatureScot website.

Further information

We do not hold records of private landowners. You can search the Land Register to find ownership details, though there may be a fee.

Take action

If you think you have found an invasive, non-native species:

• report it using our enquiry form
• send clear photos and location details
• take care not to move or spread the species
