Injurious weeds: how to make a complaint
Use this form between 1 April and 30 September to complain about an infestation of injurious weeds where there is a risk those weeds will spread to your land.
Applies to England
Complete this form if the landowner or occupier does not take action as set out in the guide Stop ragwort and other harmful weeds from spreading.
Before you complete the form
Natural England will only investigate complaints about the threat of injurious weeds spreading to land used for either:
- keeping or grazing horses and other livestock
- producing hay or silage for livestock
- other agricultural activities
The 5 injurious weeds stated in the 1959 Weeds Act are:
- Common Ragwort (but not other types of Ragwort, such as Oxford, Hoary and Marsh Ragwort)
- Spear Thistle
- Field Thistle
- Curled Dock
- Broad-Leaved Dock
You must have made reasonable efforts to contact the landowner or occupier where the weeds are growing, and given them suitable time to respond.
The online complaint form is available from 1 April to 30 September.
When you can make a complaint
You can make a complaint from 1 April to 30 September.
You cannot make a new complaint between 1 October and the end of March. This is because weeds die off for the winter and cannot be seen on a site inspection. Any new complaints made during this time that are not about an open valid case will not be reviewed.
Natural England will aim to respond to valid complaint forms within 10 working days.
Other ways to complain
You can also make a complaint by email or post.
The email and post complaint form is available from 1 April to 30 September.
Email the form to weedenquiries@naturalengland.org.uk or post it to:

Action landowners must take
If the complaint is valid and the weeds are considered high risk, Natural England will write to the landowner or occupier asking them to remove the weeds by a specific date.
Landowners or occupiers are usually asked to clear the weeds within 28 days from the date of the letter.
During June, July, August and September, landowners or occupiers will be asked to clear the weeds within 14 days.
Weeds considered low risk
If weeds are considered low risk, Natural England will not usually take action straight away but will ask you to:
- continue to monitor the spread of the weeds
- contact an adviser again within 12 months if you think the risk of weeds spreading is increasing
Your personal information
If Natural England acts on your complaint, it will not usually reveal your identity to the occupier of the land you have complained about.
However, in some circumstances Natural England may be legally required to reveal your name to the occupier of the land concerned. This means we cannot guarantee your anonymity.
After the deadline
If the landowner or occupier says they have cleared the weeds by the date specified, and you do not object, Natural England will take no action.
You can inform Natural England if the landowner or occupier has not cleared the weeds. You should do this within 2 weeks of the date specified. In these cases, Natural England will inspect the land.

Horses and livestock
If injurious weeds have already spread to land where horses or livestock are kept, this is an animal welfare issue and Natural England will not investigate further.
Contact the RSPCA, British Horse Society or Animal and Plant Health Agency (APHA), who have animal welfare officers and may investigate:
- RSPCA: 0300 1234 555
- British Horse Society: 02476 840 500
- APHA: 03000 200 301
Non-native plants
Non-native, invasive plants are not listed under the 1959 Weeds Act.
These include:
- Japanese Knotweed
- Himalayan Balsam
- Giant Hogweed
We have no regulatory powers to control these plants.
For advice on invasive non-native plants, read How to stop invasive non-native plants from spreading.
