Invasive and non-native weeds

Non-native plants are those that have been brought in to the country. A small number of these can cause damage to the environment and our health. These are called invasive non-native weeds.

For more advice on how to deal with invasive non-native weeds visit GOV.UK

Invasive non-native weed control

Responsibility for dealing with invasive non-native weeds, such as Giant Hogweed and Japanese Knotweed, rests with individual landowners.

On District Council owned land

If we find an invasive non-native weed on our land we will arrange for it to be removed by appropriately qualified weed removal contractors. 

On privately-owned land

Contact the responsible landowner or occupier and ask them to prevent any weeds that are spreading on to your land and that are controlled by law.

For further advice see GOV.UK

Identifying invasive non-native weeds

For helpful identification guides, with detailed seasonal photographs, see the Non-native Species Secretariat website.

Incidents of Giant Hogweed and Japanese Knotweed are rare in West Oxfordshire.

Giant Hogweed

It has a similar appearance to cow parsley with long, green stems which branch out into clusters of small, white flowers. However, it can grow to over 3 metres and can be identified by its purple-hued stem and leaf stalks covered in spots.

Japanese Knotweed 

The different seasons bring out different characteristics of the plant with red or purple shoots appearing from the ground at the start of spring, which then grow rapidly into canes and grow leaves.
