Duration
3 years
How much you’ll be paid
£4 per 100 metres (m) for both sides
Action’s aim
This action’s aim is that there are ditches with:
-
varied bankside and aquatic vegetation
-
undisturbed wildlife habitat
The purpose of this is to:
-
maintain vegetation that’s typical of wet ditches
-
provide habitats for wildlife
Where you can do this action
An eligible ditch for this action must:
-
form part of the boundary of a land parcel that’s located below the moorland line
-
be a man-made, long and narrow linear channel that’s cut into the ground for the purpose of draining the land or managing water levels
-
have vegetated banks
-
regularly contain standing or flowing water
The following features are not eligible for this action:
-
ditches located in a severely disadvantaged area (SDA) below the moorland line
-
culverts or underground drains
-
natural watercourses, such as streams
-
non-linear water features, such as ponds, lakes or reservoirs
-
grips, gutters and foot drains
Check you have management control of your ditches
You must have management control of both sides of the entire length of the eligible ditch you enter into this action for its 3-year duration.
If you only have management control of one side of the ditch, you must not enter it into this action.
You will have management control of both sides of a ditch that borders a neighbour’s land if you meet both of the following conditions:
-
you have a legal right or obligation to manage the ditch
-
you can meet this action’s requirements
You cannot do this action on ditches managed by third parties, such as Internal Drainage Boards.
Check the length you enter into this action
It’s your responsibility to check that the length (in metres) you enter in your SFI application:
-
is eligible for this action
-
corresponds with what’s on the ground for the relevant land parcel
If you enter a length which is ineligible or exceeds what’s on the ground, the Rural Payments Agency (RPA) will have to remove it from your SFI26 agreement. You may also have to repay monies already received.
Eligibility of protected land
Sites of special scientific interest (SSSIs): Ineligible – you must not enter any area that’s designated as an SSSI into this action.
Historic and archaeological features: Eligible – you must get an SFI HEFER before you do this action (read section 5.3 ‘Land with historic or archaeological features’ in the SFI26 scheme information to find out how to do this).
Rotational or static action
This action is static. This means you must do it at the same location each year of this action’s duration.
What to do
You must manage the ditch in a way that can reasonably be expected to achieve this action’s aim, including:
-
cutting vegetation at the top of the ditch bank in rotation, so you only cut up to half the length of the ditch bank in any year of this action’s 3-year duration
-
carrying out in-channel management on any section of the ditch no more than once during this action’s 3-year duration – this includes cleaning out silt or vegetation and cutting vegetation in the ditch channel
To minimise disturbance to wildlife, you must only manage the ditch during the autumn, winter and early spring (usually September to late March).
You must not re-profile or increase the width or depth of the ditch.
When to do it
You must do this action from its start date, throughout each year of its 3-year duration.
If this action’s start date means it’s too late for you to do this action, you must start doing it within 12 months of the action’s start date.
How to do it
It’s up to you how you do this action, as long as you:
-
follow this action’s requirements – these are identified by a ‘must’
-
do the action in a way that could reasonably be expected to achieve this action’s aim
You may find it helpful to read the ‘advice to help you do this action’, but it’s not part of this action’s requirements.
Evidence to keep
Keep evidence to show what you’ve done to complete this action, such as:
-
ditch management operations at a land parcel level and associated invoices
-
photographs and other documentation
If it’s not clear that you’ve done this action in a way that could reasonably be expected to achieve its aim, we may ask for this evidence. You must supply the evidence if we ask for it.
Other actions or options you can do on the same area as this action
You can do the following actions or options on the same area in a land parcel as this action.
| Scheme | Action or option codes | |
|---|---|---|
| SFI 2026 actions | All SFI 2026 actions except BND1 | |
| SFI 2024 actions | All SFI 2024 actions except BND1 and WBD2 | |

| ES options | All ES revenue options except boundary options |
If an action or option cannot be located on the same area, you may be able to do it on a different area in the same land parcel. Read section 5.6 ‘Land that’s already in other funding schemes or grants’ in the SFI26 scheme information for more details.
Advice to help you do this action
The following advice may help you to do this action, but it’s not part of this action’s requirements.
Managing ditches
To help you achieve this action’s aim, you can:
- cut vegetation at the top of the ditch bank (where needed) with cutters set high, to leave vegetation that’s around 10 centimetres (cm) to 15cm high
- carry out bankside cutting (where needed) during late summer or early autumn
- carry out in-channel management using appropriate machinery and without affecting the banks
- work from one bank only, leaving short stretches (for example, around 10m to 20m) undisturbed to provide a refuge for wildlife
- progress work upstream to allow dislodged pieces of plant and invertebrates to float downstream to live in the ditch again
- leave around at least one third of the overall ditch area undisturbed each year – managing your ditches less frequently will provide undisturbed habitat for wildlife (including the water vole)
Make sure you follow the farming rules for water. These require you to take steps to stop manure, fertiliser or soil getting into waterbodies and watercourses. Maintaining good water quality in your ditches will help to protect insects or plants that live in them.
Before you carry out work on your ditches, check if you need to get consents or permissions. Read section 10 ‘Get any regulatory consents before you do your SFI actions’ in the SFI26 scheme rules and guidance.
You may find it helpful to read Farm Wildlife’s guidance on managing ditches.
Cutting vegetation
To cut vegetation at the top of the ditch bank in rotation, you can either:
- cut one side of the ditch and leaving the other side uncut as a wildlife corridor
- leave alternate sections uncut
You can control weeds on the ditch banks by cutting or hand pulling. If you need to use herbicides:
- follow the label recommendations
- get permission from the Environment Agency before you use herbicides to control weeds and unwanted vegetation in or close to a river or watercourse
Carrying out in-channel management
Carrying out in-channel management of your ditches on a rotation will help to provide a range of different conditions to benefit many species. For example:
- insects, that need shallow water, muddy areas and flower-rich bankside vegetation
- birds like warblers, that need tall vegetation and reeds
If you carry out in-channel management on the ditch, you can deposit the silt and vegetation (known as ‘spoil’) on the field adjacent to the ditch. However, under a D1 waste exemption, you can only deposit up to 50 cubic metres of dredging spoil on each metre length of land during any 12-month period. Read the guidance on D1 waste exemption: depositing waste from dredging inland waters for more information.
When you deposit the spoil, try to avoid:
- spreading it on areas of grassland that are rich in wildflowers
- using it to infill low lying areas
- spreading it on the ditch’s bank face
- spreading it on land with historic or archaeological features
- creating spoil banks in wet grassland and wetland areas, as they stop water movement on and off the field
Controlling invasive, non-native species
Invasive, non-native species (such as Himalayan balsam and Japanese knotweed) can shade out or out-complete native plants in your ditch.
You may need to:
- monitor and control invasive, non-native plant species to stop them spreading
- get advice if your ditch contains invasive water plants like crassula (New Zealand pygmyweed) or floating pennywort
- dispose of ditch spoil that contains invasive, non-native species safely, instead of spreading it on the adjacent field
