Invasive Species Week

Last edited: May 15, 2022, 7:48 PM

Over 2,000 plants and animals have been introduced to GB from all over the world by people. These are known as non-native species. Most are harmless, indeed the majority of our agricultural species (wheat, barley, sheep etc) are not native to GB, but around 10-15% become invasive non-native species which spread and have a harmful impact.

Invasive non-native species are one of the top five drivers of global biodiversity loss. Here in GB they threaten the survival of native wildlife, damage our natural ecosystems, cost the economy over £1.7 billion a year, and can even harm our health and interfere with activities we enjoy. 

What is Invasive Species Week? 

Invasive Species Week is an annual national event to raise awareness of the impacts of invasive non-native species, the simple things that everyone can do to prevent their spread, and some of the fantastic work taking place across the UK, Ireland, Jersey, Guernsey and Isle of Man to protect the environment and reduce their impacts.

How can I protect the environment?

There are five simple things that you can do to help prevent the spread of invasive non-native species. If you want to know more, view our guidance for different groups.

 

  Keep any boats, clothing, footwear and equipment used in water free of invasive non-native species – remember to Check Clean Dry after use.  
Be Plant Wise and don't let your garden, pond, or aquarium plants enter the wild.
Take care of your pets, never release them or allow them to escape into the wild. It’s cruel and could harm other wildlife. 
Look out for Asian hornet and other alert species and record your sightings. Read more on Asian hornet and how to report sightings, find free ID sheets for invasive non-native species.
If you enjoy being outside why not volunteer with a Local Action Group working on invasive species management.
