Invasive Plant Species
We can manage and eradicate invasive plant species.
As well as Japanese Knotweed, we can manage and eradicate all plant species as set out in the Wildlife and countryside act 1981 Section 14 Schedule 9. This includes other invasive plants.
Under the act, it is illegal to plant or otherwise cause to grow in the wild any plant listed in schedule 9.
Well known examples such as
Himalayan Balsam (Impatiens glandulifera)
Himalayan Balsam is an annual plant grows, flowers and then produces seed pods which burst and throw 700-3,000 seeds per plant around a 7m radius; the plant will then die.
The seed is viable for 1-2 years with most actually germinating the following year.
The key to control is to kill all plants before seeding.
Giant Hogweed (Heracleum mantegazzianum)
Giant Hogweed is a perennial plant, it was first introduced to Britain in 1893 as an ornamental plant. It spread from gardens and now covers many areas of wasteland and riverbanks in the British Isles. By forming dense stands, it can displace native plants and reduce wildlife interests. During winter when the plant has died back it leaves the area bare of vegetation and increasing the risk of erosion and re-colonisation from seeds washed downstream.
Growth is from seed which can be viable for up to 5 years.
Health Hazard – Skin contact with sap from the plant can cause 2nd-degree burns, Eye contact with the sap can cause permanent blindness.
Pathways of Spread – Spread is primarily by the distribution of seeds by wind, with further spread by flowing water and by-passing animals and humans, movement of soils containing seed or plants, will introduce the plant to entirely new areas.
