welcome

Welcome to the Scottish Invasives blog. Invasive non-native species (or INNS) are plants and animals that have been introduced to areas outside their natural range. INNS are currently recognised as one of the greatest threats to biodiversity. The Scottish Invasives blog is intended as an informal forum for those interested in invasive species control. If you wish to contribute, please get in contact. You can click on any of the images to see them at higher resolution.

Reaching for the sky


Giant hogweed. Everything about this plant is big, even its name ... Heracleum mantegazzianum.

It is a biennial, so individual plants die after flowering. However, its seeds can survive up to 5 years in the soil, so whatever treatment is used, control must be continued for at least 5 years on any given site.

Water Users Beware!

Our waterways are under threat from invasive aquatic species.

As a water user, you may unknowingly be helping to spread invasive species from one waterbody to another in equipment, shoes and clothing.


Help stop this happening by following these three simple steps: Check, Clean, Dry.



Check your equipment and clothing for living organisms


Pay particular attention to areas that are damp or hard to inspect




Clean and wash all equipment, footwear and clothes thoroughly

If you do come across any organisms, leave them at the waterbody where you found them



Dry all equipment and clothing: some species can live for several days in damp conditions

Make sure you don't transfer water elsewhere
