Hampshire & Isle of Wight Wildlife Trust

What is it about?

Hampshire & Isle of Wight Wildlife Trust will be working with landowners to reduce the damage caused to the natural heritage of the New Forest by invasive non-native species.

Himalayan balsam, Japanese knotweed, giant hogweed and American skunk cabbage will be targeted, with control measures implemented where bankside non-natives are a serious and expanding issue.

The main aims will be to:

  • Reduce the distribution and abundance of key invasive non-native species along Lymington River and its tributaries, Cadnam River and Avon Water
  • Deliver training courses which will increase the skills of land managers to identify and control the spread of invasive non-native species.

Over the last two summers (2016 and 2017) work has been carried out with over 80 landowners to remove non-native invasive species. Over 300 people have volunteered on work parties to remove Himalayan balsam at 89 sites and further volunteer task days are planned for summer 2018.

Volunteering and training

If you are interested in volunteering to help with the work of New Forest Invasive Non-Native Plants, visit the volunteering pages for further information on upcoming volunteer task days.


The landowners of the stretches of riverbank habitat will be encouraged to keep any new infestations under control once New Forest Invasive Non-Native Plants officers have demonstrated that eradication of these species is both achievable and desirable.
