Appendix I – Habitats on road verges
Road verges are associated with nearly all Habitat Action Plans in Surrey.Chalk grassland (including chalk scrub)
Associated mainly with the chalk of the North Downs.Lowland heath (including acid grassland and bog)
Associated with the Surrey heaths.Lowland unimproved neutral and dry acid grassland (meadows)
Associated with the low and high weald and the Thames basinUrban (Wildlife on your doorstep)
Provides opportunities to improve areas where people live. Verges provide valuable links and corridors for wildlife through urban areas.Standing open water and large reedbeds
Localised features throughout the network.Woodland
Localised remnant areas of woodland and individual trees throughout the networkWetland (rivers and streams, fen, marsh, swamp and linear reedbed)
Found primarily in association with boundary ditches, and other areas with remnant vegetation.Wood pasture and parkland
Occasional remnant features such as parkland trees within the highway verge.Floodplain grazing marsh
Possible areas of remnant vegetationFarmland (including hedgerows)
Hedges on and alongside verges may be associated with farmland.Priority Habitats

- Standing open water and canals (e.g. lakes, reservoirs, ponds, aquifer fed fluctuating water bodies)
Appendix II –Species associated with road verges in Surrey
Road corridors can support a rich diversity of plants and animals and make a considerable contribution to biodiversity. The Surrey Biodiversity Information Centre will work with County Recorders in Surrey to come up with a list of characteristic and priority species that occur on road verges in Surrey. The list will be available from the Surrey Biodiversity Information Centre and the Surrey Biodiversity Partnership website.Appendix III – Site and species designations, legislation and guidance
Site designations
Some road verges are part of larger sites designated for their value for biodiversity. Others are selected as Site of Nature Conservation Importance or a Conservation Verge. Any work carried out on road verges that are, or are adjacent to a designated or selected site should take into account the effect of that work on the verge.- Special Protection Area (SPA – a European designated site)
- Special Area of Conservation (SAC – a European designated site)
- National Nature Reserve (NNR)
- Sites of Special Scientific Interest (SSSI)
- Local Nature Reserve (LNR)
- Site of Nature Conservation Importance (SNCI)
- Conservation Verge
Species designations
Over the past thirty years, numerous lists of the conservation status of species have been produced – Red Lists, Biodiversity Action Plan Priority Lists, species listed on European Directives, species listed on the Schedules of the Wildlife & Countryside Act – each produced for differing reasons, based on different criteria and with considerable overlap between each list. As a result, the relative status of a particular species can often be confusing. However, in recent years, determined efforts have been made to ensure constancy between different taxonomic groups with the adoption of internationally agreed criteria (the so called IUCN criteria) which provide a measure of how threatened a particular species is based on measures of population size and geographic range. Species thought to be rare or threatened at the UK level are assigned to one of six categories as follows;- Extinct in the Wild - A species is Extinct in the Wild when it is known to survive only in cultivation, in captivity or as a naturalised population (or populations) well outside the past range.
- Critically Endangered - A species is Critically Endangered when it is facing an extremely high risk of extinction in the wild.
- Endangered - A species is Endangered when it is facing a very high risk of extinction in the wild.
- Vulnerable - A species is Vulnerable when it is facing a high risk of extinction in the wild.
- Near Threatened - A species is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future.
- Least Concern - A Species is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Species can however be considered Nationally Scarce.
- RDB 1 – Species in danger of extinction and whose survival is unlikely if the causal factors continue operating.
- RDB 2 – Species believed likely to move into the Endangered (RDB 1) category in the near future if all the causal factors continue operating.
- RDB 3 – Species which exist in only fifteen or fewer 10 Kilometre Squares of the National Grid system. These are Taxa with small populations that are not at present Endangered (RDB 1) or Vulnerable (RDB 2), but are at risk.
- RDBK – Taxa suspected to fall within the RDB categories but with too little information to allow confident assignment to particular category.
- Nationally Scarce - Notable/Na; species estimated to occur within 16-30 10-kilometre squares of the National Grid system.
- Nationally Scarce - Notable/Nb; species estimated to occur within 31-100 10 kilometre squares of the National Grid system.
- Nationally Local; species estimated to occur within 101-700 10 kilometre squares of the National Grid system.

Appendix V- Recommended Management for Conservation Verges
The Road Verge HAP working group will work out further details regarding the cutting of Conservation Verges. Cut A – April For those verges with summer flowering species, and those that require 2 cuts Cut B – August For verges with species present during June and July Cut C – September / October For all other verges, and those that require 2 cuts.General management principles
- Cuttings should be collected and either removed from the site or disposed of in an appropriate manner,
- Full width cuts where practical will prevent scrub invasion.
- Height of cut and machinery used should be considered.
- Check for Priority species such as amphibians and reptiles prior to major works. Contact the BIC or carry out surveys as appropriate.
Appendix VI – Trees
Any work carried out on trees should:- Comply with Surrey Highways Arboricultural Specifications and Guidance Note and SCC Arboricultural Policy Guides
- Reflect natural vegetation patterns and species for any new woodland planting as described in “The Future of Surrey’s Landscape and Woodlands” (Surrey CC 1997), and comply with guidelines in MaPS
- Comply with the Habitats Regulations. The Forestry Commission website has information: www.forestry.gov.uk/england-protectedspecies
- Take into account Tree Preservation Orders (TPO’s) and Conservation Areas (under the Town and Country Planning Act)
- Comply with the Hedgerow Regulations 1997
- Take into account advice contained in the English Nature Publication: ‘Veteran trees: a guide to good management’
- Consider advice given in the Natural England publications: ‘Hedgerow trees: answers to 18 common questions’ and ‘Hedge cutting: answers to 18 common questions’
Appendix VII – Injurious and noxious weeds
The Highway Authority has a statutory responsibility under the Weeds Act 1959 and the Wildlife and Countryside Act 1981 (as amended by the Countryside and Rights of Way Act 2000) to control the spread of injurious and noxious weeds and invasive plants. The current prescribed weeds under the various legislation are:Weeds Act 1959 in relation to agricultural weeds:
- Common ragwort Senecio jacobaea
- Broad-leaved dock Rumex obtusifolia
- Curled dock Rumex crispus
- Creeping thistle Cirsium arvense
- Spear thistle Cirsium vulgare
Ragwort Control Act 2003:
Amends the Weeds Act and promotes the more efficient control of common ragwort. It enables the Secretary of State to make a ‘Code of practice to prevent the spread of ragwort’.Wildlife and Countryside Act 1981 (Schedule 9) in relation to conservation:
- Giant hogweed Heracleum mantegazzianum
- Japanese knotweed Fallopia japonica
Other problem species
- Himalayan Balsam Impatiens glandulifera
- Rhododendron Rhododendron ponticum
Appendix VIII – Case Studies
This section describes Case Studies where measures have been implemented to protect, maintain or enhance the biodiversity of road verges. The examples given include schemes from within the County and elsewhere, where these are particularly relevant to the aims of this RVHAP. Case studies range from examples for routes or longer lengths of network down to work on individual sections of verge.Major Highway Improvements: The A31 / A331 Blackwater Valley Route
The Blackwater Valley Countryside Partnership manages a total of 86 hectares of amenity land alongside the A31 and A331 on behalf of Surrey and Hampshire CC. This large expanse of land resulted from land purchases made at the time of highway design and construction during the period 1992-1996, in order to provide appropriate levels of mitigation for the new highway route, and secure land required for viable habitat relocation, creation and management. The Blackwater Valley Route (BVR) covers a distance of 15 kilometres, and areas retained and enhanced for biodiversity, recreation and amenity extend to distances up to 50 metres either side of the road corridor. This Green Corridor provides:- A buffer between built up areas of Farnborough, Aldershot and Badshot Lea to the west and Mytchett, Frimley, Ash Vale and Tongham to the east;
- A mosaic of linked open spaces and habitats including a number of pocket parks, large lakes, rivers, streams, ponds and other wetland habitats, together with large areas of woodland, scrub and verge associated with the route
- A long distance footpath that connects Frimley with the Hog’s Back.
Managing Existing Routes: Green Corridor Action Plans (GCAP)
Green Corridor Action Plans form one of the principal methodologies for implementation of the RVHAP. The GCAPs follow an identical structure and layout. The aims of GCAPs are:- To define the character and key issues associated with a route and to set out long term objectives to strengthen the landscape character and biodiversity of the road corridor, in accordance with defined targets
- To set out a five year action plan to address priority issues for the route
- A24 Givons Grove Roundabout to Capel (17 kilometres)
- A31 Hogs Back (18 kilometres)
- B375 Chertsey Bridge Road to Gaston Bridge Road (4 kilometres)
- A320 St Peters Way (1 kilometre)
Young Street Chalk Grassland
The A246 Young Street runs from Givons Grove south of Leatherhead, to the junction of the B2122 and A246 Guildford Road at Fetcham. This stretch of highway is on the North Downs and is within the Surrey Hills Area of Outstanding Natural Beauty. The site, which comprises species rich chalk grassland and scrub, lies south of the A246, west of the Young Street car park and railway bridge, towards Bocketts Farm. Fields and open grassland associated with Norbury Park and Bocketts Farm lie to the south and north. The site is approximately 1.8 hectares (3.4 acres) in extent, measuring some 560 metres length by 2-15 metres width. It is separated from the highway corridor by a deep ditch and is bounded to the south by a steep, high, north facing embankment, comprising exposed chalk, and including chalk scree at its base. A botanical survey by the Surrey Wildlife Trust identified 113 plant species on this short section of verge in July 2004. The survey included management recommendations and these have been incorporated in the A24 Givons Grove to Capel Green Corridor Action Plan, as the verge lies just to the west of the Givons Grove Roundabout. Volunteers and a contractor have carried out scrub clearance in accordance with the survey recommendations, and SWT will continue to monitor the site, initially on an annual basis. The Young Street verge has been set up as a demonstration project for verge management, combining routine maintenance operations carried out by the Term Maintenance Contractor with conservation management carried out by volunteers from the Lower Mole Countryside Management Project.RVHAPs elsewhere in the UK
The value of roadside verges as a reservoir for wild flowers and invertebrates has long been recognised by Suffolk Wildlife Trust, which was the first organisation to set up a roadside nature reserve scheme 30 years ago. Currently there are some 35 kilometres of verge in Suffolk that are protected, ranging in lengths from 40 metres to 3.5 kilometres. All protected verges are marked either end by white posts with a plate bearing the words ‘Roadside Nature Reserve’ to identify the verge to both the contractor and the public. Each verge is cut once a year, normally in October after flowering and seeding, except for a few selected sites, which are cut in July. Volunteers provide management input on some sites, and this includes raking up cuttings left by the contractor. The project continues to be fully supported by Suffolk County Council. Nottinghamshire also has ‘Notified Road Verges’ designated by the County Council who manage in excess of 75 kilometres of unimproved neutral grassland in the county. Northampton County Council has designated and manages 21 protected roadside verges. 130 Roadside Nature Reserves have been created in Kent, in partnership with Kent Wildlife Trust and the County’s Highway Authority. A network of volunteer ‘verge wardens’ assist with the management and surveying of these designated verges.Verge Management in the Netherlands
The Netherlands has adopted the principle of ‘Ecological Verge Management’, based on one or two annual cuts and removal of cuttings. This is a similar approach to traditional ‘hay making’, and has led to a dramatic improvement in diversity of species and presence of animals in verges, even alongside major highway corridors. It has been found that the cutting regimes, based on sound ecological principles, employed by the Dutch have proved no more expensive than the cutting regimes previously adopted. The Dutch have shown that the construction and maintenance of verges aimed at the creation and preservation of rich natural habitats is both feasible and achievable. In the Netherlands, where verges are now routinely managed for wildlife conservation objectives, in excess of 760 plant species have been recorded in verges, which accounts for over 50% of all plant species occurring throughout the Country, and the range of species favouring verges varies from the common place to those that are relatively rare or even threatened. A great deal of work has been undertaken in the Netherlands on addressing the impacts of fragmentation caused by highway corridors on wildlife through modified design and management of verges. This has included the creation of alternative/replacement habitats, enhancement/extension of existing marginal habitats, creation of linear links based on natural corridors such as canals and rivers, and the construction of purpose designed crossing points such as green bridges, tunnels, and linear wetlands. In achieving biodiversity improvements the Dutch have applied ‘Ecological Engineering’ techniques. This includes departure from normally accepted engineering procedures relating to earthworks, particularly in relation to grading operations (e.g. roughly formed, uneven soil surfaces and formation of deliberate humps and hollows). Progressively, verges in the Netherlands are providing a sanctuary for species displaced or under threat in other habitats, and it has been found that 160 plant species, which is 10% of all plant species occurring in the Netherlands, can only survive reliably in roadside verges because there are no other suitable habitats left. In particular, plant species once familiar in agricultural landscape now flourish in roadside verges and directly contribute to species diversity.Appendix IX – Useful publications
