Working together to protect Cornwall’s landscapes and waters 

The Cornwall Invasive Species Forum, hosted by South West Lakes Trust and kindly funded by CINNG (Community Invasive Non-native (Species) Group), brings together environmental charities and trusts, local authorities, statutory agencies, water companies, land managers, wildlife groups, volunteer networks, academic and research organisations to tackle the growing challenge of invasive nonnative species across the county. By sharing knowledge and supporting coordinated action the Forum plays a vital role in safeguarding Cornwall’s unique habitats, wildlife, and waterways. This collaborative approach ensures that expertise, resources, and local knowledge are shared and have the most impact. 

Why are invasive species a problem? 

Invasive nonnative species are one of the biggest threats to biodiversity in the UK. Plants and animals such as Himalayan Balsam, Japanese Knotweed, Grey Squirrel and Crassula can spread rapidly, outcompete native species, damage infrastructure, and impact recreation and water quality. 

Cornwall’s lakes, rivers, moorlands, and coastal catchments are particularly vulnerable — and once invasive species become established, they are costly and difficult to control. The Forum exists to help prevent new introductions, respond quickly to emerging threats, and support longterm management. 

Our role as host 

South West Lakes Trust hosts the Forum as part of our commitment to protecting the environment, enhancing biodiversity, and supporting resilient ecosystems across the South West. As host, we: 

  • Coordinate meetings, workshops, and training
  • Facilitate information sharing between members
  • Support catchment wide planning and prioritisation
  • Provide access to expertise from our own environment team
  • Help connect local action with regional and national initiatives 

The Forum is open, collaborative, and designed to empower everyone working to protect Cornwall’s natural environment. 

What the Forum does 


The Cornwall Invasive Species Forum focuses on practical, joined up action. Key areas of work include:
 

  • Sharing best practice in identification, control, and biosecurity
  • Supporting rapid response to new or high-risk species
  • Supporting volunteer groups and community projects
  • Developing county-wide strategies for priority species
  • Raising awareness through events, training, and resources
  • By working together, we can reduce the spread of invasive species and protect the landscapes, waters, and wildlife that make Cornwall so special.
