Japanese knotweed and other invasive non-native plants
What is the issue?
Invasive non-native plants are those species which have been “introduced” to areas outside their normal range by humans and have the ability to spread and pose serious threats to biodiversity, the economy and human health. The invasive non-native plants that cause serious problems include Japanese knotweed, Himalayan balsam and Giant hogweed. These plants threaten our native biodiversity by crowding out native species and destabilising river banks. They can also cause damage to forestry, agriculture and infrastructure sectors.
Japanese knotweed, for example, can grow through tarmac and can cause structural damage to property, whilst Giant hogweed can cause harm to human health. Individuals, businesses or organisations have a legal responsibility to prevent certain invasive non-native plants or injurious weeds on their premises spreading into the wild.
