The Blue Campaign - increasing biodiversity in grass verges

ÄûÃʵ¼°¹'s network of grass verges stretches alongside 3,000 miles of urban and rural roads, providing an excellent opportunity to enhance plant and insect diversity through careful management.

Some of our highway verges have been identified as being of significant wildlife importance. We call these conservation verges. A revised approach is being introduced to better manage these identified Conservation Verges.

Many residents are eager to improve the biodiversity of highway verges that are adjacent to their property and participate in what we call the Blue Heart Verges scheme in ÄûÃʵ¼°¹. These verges follow the principles of the Blue Campaign, founded in 2014 by wildlife filmmaker Fergus Beeley. On these verges, the number of grass cuts is reduced, allowing native plants to thrive. In some areas, additional steps such as preparing the ground and sowing wildflower seeds are also taken.

We are working to streamline and improve the management process for Blue Heart verges to increase biodiversity and reduce the complexity of grass cutting, which may vary for different verges along the same road.

Conservation verges

Our Conservation verges fall into two categories:

  • 33 verges identified as important for amphibians, particularly the Common Toad.
  • 43 verges identified for their botanical value, important for plant species and wildflowers.

Amphibian verges

Amphibians spend most of their lives on land, often far from the nearest water. They emerge in spring to travel to breeding ponds, often returning to the same locations each year. The Common Toad, in particular, is very particular about its breeding sites and may cross roads during its migration.

These verges are registered with ÄûÃʵ¼°¹ as toad crossings. To protect the toads during their migration (from 14 February to 31 March), our approach is not to allow any planned road works on these sections of road during this period. Any emergency road works will still be permitted.

Botanical verges

These verges are identified as having plant species of ecological interest.

Examples of rare plant species found on roadside verges in ÄûÃʵ¼°¹ are:

  • Man Orchid

  • Early Purple Orchid

The Plantlife good verge guide states that proper management is essential to maintain flower rich habitats on road verges.  Without it, many grassland flowers quickly disappear, and coarser vegetation takes over, eventually turning uncut verges into scrub and woodland.

We aim to manage these conservation verges differently from the standard rural and urban grass cutting programmes to preserve the identified plant species.

To help plants thrive, it's crucial that they grow, flower, and set seed. Cutting plants before they flower deprives insects of nectar and stops plants from reproducing. Regular and early cutting can quickly eliminate some species.

Removing grass cuttings helps reduce the growth of vigorous plants that out-compete others, lowers soil nutrient levels, and removes dead vegetation, providing space for new seeds to germinate.

There are three cutting regimes for managing botanical conservation verges, all of which involve removing the cut vegetation:

  • Cut A in April: For verges with summer-flowering species requiring two cuts.
  • Cut B in August: For verges with species active in June and July.
  • Cut C in September to October: For all other verges and those requiring two cuts.

Some Conservation Verges have invasive scrub encroaching upon them, which outcompetes the native plants. Our ecologists survey these verges and will recommend whether scrub clearance is needed before following the cutting regimes.

Our standard grass cutting programme

The standard for grass cutting across ÄûÃʵ¼°¹ is 6 urban cuts, 2 rural cuts and 2 high speed road cuts every year.  In general, an urban area is a built up area with a speed limit of 40mph or less.  A rural road is one which tends to have a lower density of buildings than an urban road and is often tree and hedge lined.

We do not collect grass cuttings following mowing, but they should be spread evenly over the surface.  We acknowledge and understand the advantages of removing grass cuttings, but raking up, loading, transporting and disposing of grass cuttings would increase our costs substantially.

Further details on our grass cutting programme can be found here: Grass cutting, verges and weeds.


Blue Heart verges

The goal of Blue Heart verges is to increase biodiversity by reducing the number of grass cuts per year on specific verges, allowing wildflowers and the insects that rely on them to thrive.

When residents apply for a Blue Heart verge, we need to assess its suitability for inclusion, taking into consideration likely biodiversity benefit and road safety. On Blue Heart verges, the vegetation is cut once, raked and removed at the end of the season, usually around October. Plaques are usually installed so residents can identify the verve is part of the scheme and to help our contractors who cut our verges.  Some verges are not suitable for this treatment as allowing the vegetation to grow may impact road safety.

Residents participating in the Blue Heart scheme are encouraged to remove litter where safe to do so.   Removing the cut vegetation helps reduce soil fertility and prevents the cuttings from rotting down on the verge.  This encourages wildflowers which generally thrive on poorer soils.

It is necessary to cut sightlines at junctions and access points for road safety. Strips of the Blue Heart verge will also be cut to prevent vegetation from encroaching onto the road or pavement.

The most successful Blue Heart verges have been the larger ones, such as the verge on the A246 Guildford Road in Bookham, north-east of Rectory Lane.

Previously we have supported smaller  Blue Heart verges outside individual properties, which haven't always been as successful. They often have more coarse vegetation than wildflowers, which can lead road users to believe the verge has been overlooked during grass cutting, resulting in complaints.

New process to participate in Blue Heart Scheme

We’ve reviewed and updated our process to make it easier for communities to enhance local biodiversity through the Blue Heart scheme.

  • Applications for Blue Heart verges: We now only accept applications from community groups, rather than individual residents.

Minimum Verge Size for Blue Heart verges: A new minimum size requirement has been introduced.

  • Where the verge is between the road and pavement (footway): 3m wide x 10m long
  • Where the verge is between the highway boundary and pavement: 2.5m wide x 10m long
  • Where the verge is between the highway boundary and the road: 2.5m wide x 10m long

Diagram showing minimum size requirements for Blue Heart Verges. Three scenarios are illustrated: (1) A verge between the road and pavement must be at least 3 meters wide and 10 meters long. (2) A verge between the highway boundary and pavement must be at least 2.5 meters wide and 10 meters long. (3) A verge between the highway boundary and the road must also be at least 2.5 meters wide and 10 meters long.

There is the need for us to leave a 0.5m strip at the edges of any Blue Heart verge next to roads or pavements.  This helps to prevent vegetation from growing into the road or pavement and causing an obstruction.  These dimensions allow for a minimum 2m width and 9m length of wildlife habitat .

Why these sizes?

We’ve determined these sizes based on the Lawton principle, which states that nature recovery works best when it is functionally connected to other nature-rich areas, providing a vital habitat for protected species.

The Lawton principle came from the 2010 report and can be found in

Do you want to install a Blue Heart in the verge?

If your application is successful, we will install a Blue Heart marker, so it is readily identifiable.

We will continue to support existing Blue Heart verges that do not meet the new minimum size requirements by cutting , raking and removing the vegetation at the end of the season, until residents advise us otherwise. Please do this using Fix My Street:  Fixing ÄûÃʵ¼°¹'s streets.

All of our contractors are fully aware of the Blue Heart verges and understand that these areas are maintained differently from regular highway verges. The verges are clearly marked and shown on our maps. Despite our best efforts, occasional mistakes may occur, resulting in some areas being cut. If this happens, our contractors will repair, reseed, or replant the area at no cost to the taxpayer. If necessary, they will also notify the individual or organisation that initially promoted the Blue Heart verge.
