How this item will benefit the environment

It will restore the wildlife value of overgrown or neglected ditches and help to establish raised water levels for restoring or creating habitats.


Agreement holders are likely to need to:

  • carry out the restoration work between 1 July and 28 February (the exact timing will be determined by the pre-application assessment)
  • only re-profile or cut deeper than the original profile by agreement with the adviser
  • if re-profiling, create a variety of depths in the channel, from 70cm to 100cm, grading to a shallow, wet, marginal fringe
  • if re-profiling, make sure the profile varies, with most of the slopes between 30 and 45 degrees
  • work from one bank in an upstream direction, restoring only half the ditch in any one year
  • restore one side of the ditch along its full length, or alternate 100m sections along both sides
  • retain any in-channel features such as gravel beds, riffles and natural meanders
  • create berms along the sides of the ditch
  • secure material at the downstream end of the ditch during dredging or re-profiling to capture silt in the water, and remove this when any silt has settled
  • place the spoil on top of the bank or in the field next to it, making sure that it is not used to fill hollows or low areas within the field
  • make sure that the spoil is not placed on historic or archaeological features
  • spread the spoil thinly to prevent a spoil bank from forming
  • place all fences at least 1m away from the edge of the bank top

The agreement will set out what must not be done. It is likely agreement holders will not be allowed to:

  • reprofile or cut deeper than the original profile unless by agreement with the adviser
  • fill hollows or low areas within the field with spoil
  • place spoil on historic or archaeological feature

Keeping records

Agreement holders will need to keep the following records and supply them on request:

  • any consents or permissions connected with the work
  • receipted invoices, or bank statements where a receipted invoice is unavailable
  • please see the record keeping and inspection requirements as set out in the Higher Tier manual for more detail

Agreement holders will need to keep the following records and supply them with the claim:

  • photographs of the site during the different stages of construction or contracts, invoices or other documents confirming the technical specification for the completed works
  • photographs of the completed works in place and installed

Applicants will have to send the following with their application:

  • an assessment of the existing biological interest of the site, particularly related to protected species
  • a copy of any relevant consents (for example from the Environment Agency, Internal Drainage Board or Historic England)
  • photographs before works commence

The detailed requirements for this item will be tailored to the Higher Tier site. Higher Tier applicants should discuss and agree these requirements with their adviser.

Advice and suggestions for how to carry out this item

The following section gives advice on carrying out this item successfully but does not form part of the requirements for this item.

Where to use this item

Use this item on ditches that have become silted up through neglect and have channels that need to be cleaned and banks that need to be reprofiled. Using this item will create a more varied habitat for wildlife.

This item can also be used to prevent the degradation of historic environment features and waterlogged archaeological deposits by helping to support high water levels.

Re-profiling ditches, dykes and rhines

The profile of restored ditches, dykes and rhines should reflect the character of existing features in the local area.
