CT5: Creation of inter-tidal and saline habitat by non-intervention

Find out about eligibility and requirements for the creation of inter-tidal and saline habitat by non-intervention option.

How much will be paid

£494 per hectare (ha).

How long this option lasts

This option runs for 20 years, not the standard 5 years for the scheme, in recognition of the level of management change involved and its largely irreversible nature.

Where to use this option

It is available for Countryside Stewardship Higher Tier on whole or part parcels on a non-rotational basis on sites that are both:

  • next to either saltmarsh or other inter-tidal habitats
  • on land that lies behind a coastal defence - most of the land must lie below mean high water spring tide level (the average of the heights of two successive high waters when the tidal range is greatest)

Suitable sites may have:

  • defences that are overtopped by high tides
  • recently been breached and show evidence of being inundated or percolated by salt water through the defences

The creation of the inter-tidal habitat must both:

Where this option cannot be used

If the creation of inter-tidal and saline habitat is:

  • as compensation, planning consent condition or other Habitat Regulations requirement
  • on land that has previously received 20 years’ agri-environment funding for coastal habitat creation

Features that can be included in this option

You can include the following features if they are part of the land area (once inter-tidal habitat is created), even if they are not eligible for the Basic Payment Scheme (BPS):

  • open water (such as lagoons and creeks)
  • bare mud

How this option will benefit the environment

It creates inter-tidal and saline habitats, including transitional areas (transitions between saltmarsh and nearby habitats), following the unmanaged breach of sea walls or the overtopping of sea walls.

If successful there will be:

  • inter-tidal and saltmarsh areas developing (note that it will not be possible to precisely predict the balance of saltmarsh and mudflat in a dynamic coastal system)
  • a mosaic of open habitats such as lagoons, creeks and mudflats
  • saltmarsh plants colonising more stable higher areas of the habitats
  • lugworm casts, feeding birds and other evidence of marine invertebrates

As a result of tides bringing in sediment and seeds, a range of inter-tidal habitats will form such as mudflats, coastal saltmarsh, together with saline lagoons and transitions between these and other habitats where the topography promotes this. These habitats will benefit many specialised plants and animals adapted to the differing degrees of tidal inundation and saline influence. These factors result in variations in vegetation cover from bare mud to dense grassland, and succession between them over time.

The creation of small-scale saline lagoons, which require an input of seawater, can be promoted by this option. This option will also contribute to more sustainable flood management, adaptation to climate change and enhancement of the coastal landscape. Where sediment is deposited, the option may contribute to the protection of important archaeological sites from the impacts of ploughing or other forms of cultivation (but early consultation with historic specialists will be needed where such sites are present).

Requirements

If your application is successful the planned management will be detailed in a feasibility study for the site. It will include how to:

  • prepare the site and manage any existing vegetation
  • excavate any lagoons or creeks
  • manage vegetation once established
  • make any further breaches to the sea wall, where needed
  • agree all drainage works, including modification to existing drainage, in writing with Natural England before you carry out any work

Keeping records

Before you apply, contact both Natural England and the Environment Agency for advice and get the consents or permissions required. You do not need to provide the consents or permissions with your application, but you must send them with your payment claim.

You must send the following with your application:

  • a map of permitted access routes – you can mark these on any map including the Farm Environment Record (FER)

On your annual payment claim you must declare that you have not carried out any activities prohibited by the option requirements and send the following:

  • support from the Environment Agency

You must keep the following records and supply them on request:

  • receipted invoices, consents or permissions connected with the work
  • field operations at the parcel level, including associated invoices
  • any sites grazed will require a grazing activity record
  • photographs of the management undertaken

You can locate these supplements on the same area as this option:

Advice and suggestions for how to carry out this option

The following advice is helpful, but are not requirements for this item.

To make sure that transitional areas are included in the agreement area, the boundary of the agreement should normally extend to Highest Astronomical Tide (HAT) plus 1 metre. This will allow for development of transitional zone, including unusual transitions from saline to brackish to freshwater habitats. Such instances would need to be identified in the initial planning stages prior to completion of the agreement and clearly justified for individual sites.

This is a specialised option that is only likely to be used in a relatively small number of cases, where coastal defences are not being maintained and are then overtopped or breached naturally. Where a managed breach is planned, then options CT4 - Creation of inter-tidal and saline habitat on arable land or CT7 - Creation of inter-tidal and saline habitat on intensive grassland would apply.

On sites where there is interest and potential for this option, discussions should be held with Natural England and the Environment Agency at an early stage. It should be recognised that unmanaged sea wall breaches are of course unpredictable, but contingency plans can be put in place.

Biodiversity

This option has been identified as being beneficial for biodiversity. All Countryside Stewardship habitat creation, restoration and management options are of great significance for biodiversity recovery, as are the wide range of arable options in the scheme. Capital items and supplements can support this habitat work depending on the holding’s situation and potential.

The connectivity of habitats is also very important and habitat options should be linked wherever possible. Better connectivity will allow wildlife to move/colonise freely to access water, food, shelter and breeding habitat, and will allow natural communities of both animals and plants to adapt in response to environmental and climate change.
