Invasive plants

Non-native plants occur outside their natural range due to direct or indirect introduction by humans, mainly through their use in gardens.

The vast majority of non-native species pose no threat to native plants in the UK, however, a small number are highly invasive. Invasive plants are able to spread rapidly and compete aggressively with native species to form large populations that dominate a habitat.

Invasive or potentially injurious plants on public land will be investigated by the Council and if necessary, treated.

The most common invasive plants are

Giant Hogweed
Japanese Knotweed
Himalayan Balsam
