  • at risk of soil erosion or surface runoff - you can use the soil management plan produced for CSAM1 or SAM1 to identify this
  • important for buffering sensitive habitats

You must also keep evidence to show what you’ve done to complete this action, such as:

  • field operations at a land parcel level and associated invoices, including details of the seed mix used
  • stocking records to show grazing activity at a land parcel level
  • input records of nitrogen application

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 this evidence if we ask for it.

tips_and_updates Additional Advice

Advice is provided on selecting grass species tailored to local conditions, potentially including wildflowers for added environmental benefit. Regular cutting and weed control in the initial years helps establish the sward. Always check for nesting birds before cutting.
