Invasive Species Week

Last edited: Jun 28, 2022, 10:05 AM

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. 

Invasive Species Week 2022

Invasive Species Week 2022 was another fantastic week! From 16-22 May over 260 organisations across the UK, Ireland, Jersey, Guernsey and Isle of Man took part in raising awareness, holding 92 events. 

You can still find links to all blogs, videos and other resources that were published during the week, and visit @InvasiveSp (external link) or visit #INNSweek on Twitter to catch up on the action online. If you missed out this year, email us to join our mailing list for details of next year's Invasive Species Week and download our free materials:

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.
