INVASIVE SPECIES WEEK

May 12th - 18th 2025

WHAT ARE INVASIVE SPECIES?

Invasive Species are plants and animals from other countries that have been introduced and have become established outside of their normal habitat or native country. While most non-native species cause no harm, a small number become invasive and cause damage and disruption.

The spread of invasive species is a major issue in both marine and inland waters around the world. They can disrupt our boating activities, compete with native plants and animals and can cause major changes to entire ecosystems. Invasive Species are one of the top 5 highest risks to world and UK biodiversity, and cost the UK economy over £1 billion every year.

The Green Blue is a proud participant in Invasive Species Week, an annual national event raising awareness of the problems caused by invasive species and what we can all do to help.

  2. Request a Check Clean Dry Awareness Kit for coastal or inland boating venues. The kit contains outdoor A3 metal signs to display and posters to help raise awareness amongst members and customers.
