30. Eradication of Invasive Species

Themes: Quality; Habitats and wildlife


  • To maintain and enhance the river's natural habitats and wildlife
  • To increase people's awareness, appreciation, education and involvement

Project description

This project aims to eradicate invasive non-native species (INNS) from the catchment.

Invasive Non-Native Species of plants are a particular problem along rivers. There are four main plants of concern across the catchment which outcompete native wild plants and reduce the health of our rivers, wetlands and grasslands; Himalayan Balsam, Floating Pennywort, Giant Hogweed and Japanese Knotweed.
This project takes a partnership approach to eradicating INNS across the River Stort Valley. It is being led by Whoosh Explore Canoe Club in partnership with various landowners, local authorities, Environment Agency, Canal & Rivers Trust, Herts and Middlesex Wildlife Trust.
An action plan to tackle INNS has been developed and is coordinated through the Stort Catchment Partnership, which includes the organisations listed above.
Work by the group to tackle Floating Pennywort began in 2019, followed by work to tackle Himalayan Balsam in 2020 and this will continue into 2021 and beyond.
