Transport networks, green spaces, brownfield sites and development sites often become wildlife corridors and havens for biodiversity.

However certain species can be problematic if allowed to colonise. These fast-growing or noxious species can threaten biodiversity, impede development and damage infrastructure. The most commonly associated species are:

  • Japanese Knotweed
  • Giant Hogweed
  • Ragwort
  • Rhododendron
  • Himalayan Balsam

Twig can undertake:

  • Site reviews
  • Develop economical and sustainable management plans
  • Undertake the control and eradication of these invasive species

Some invasive weeds are considered so important that their control is covered by Schedule 9 of the Wildlife and Countryside Act.
