Nature Recovery Network Mapping

Building a Nature Recovery Network that works for people and wildlife

Our work is already geared towards building a Nature Recovery Network. Our nature reserves, Living Landscape projects, work with landowners and communities all works to connect landscapes together into a larger network for wildlife to move into and between, and to thrive across our whole landscape. But for our work to be even more effective - to achieve nature's recovery and a Wilder Future - we need government to commit everyone to help in the building and maintenance of a Nature Recovery Network with guidelines enshrined in law. This requires detailed information: where wildlife is abundant or scarce; where it should be in future; which places are most important; and where there is opportunity for positive change.

The critical tool is a Local Nature Recovery Map. We already have much of this information, which we use to inform our work. We believe that Government must pass an Environment Act that requires Local Authorities to publish these maps, which would identify areas where the greatest benefit for wildlife and people can be achieved. They would focus and co-ordinate effective action, funding and regulation.

If maps like this were used across the country and used by farmers as well as planners the impact for wildlife could be extraordinary.

But what would these maps look like, and how would they be created? Wildlife Trusts across the country, in partnership with local authorities and other organisations, have been working on maps such as this for many years, and using them to help guide their work. Here are some local examples.

Habitat Opportunity Mapping in Northamptonshire

In order to support our work in enhancing and connecting our Living Landscapes in Northamptonshire, we have worked with a wide range of organisations as part of the Nene Valley Nature Improvement Area partnership to produce maps showing opportunities to create new habitats for the benefit of both people and wildlife across the whole of Northamptonshire and Peterborough. 

The maps identify potential areas for the expansion of key habitats which are able to deliver particular benefits including biodiversity, the regulation of flooding and air quality, and people's access to green space. They can then be used to assist with the development of green infrastructure strategies and planning, giving decision-makers an evidence-based map to refer to when making these key decisions.

What's been mapped

Opportunities have been mapped to:

  • enhance biodiversity for three different broad habitat types (broadleaved and mixed woodland, semi-natural grassland, and wet grassland and wetland),
  • reduce surface water runoff (and hence flood risk),
  • reduce soil erosion and improve water quality,
  • ameliorate poor air quality, and
  • increase public access to natural green space.

The biodiversity opportunity maps highlight areas that are best located in terms of their connectivity to existing habitat patches and are therefore most appropriate from an ecological point of view. 

The results

The different opportunity areas vary in their geographic location; the greatest opportunities for reducing water flow are situated to the west of the study area on hillier terrain, whereas water quality opportunities tend to be adjacent to water courses. Air quality and accessible green space opportunities are focussed in and around the major towns. 

Broadleaved and mixed woodland biodiversity enhancement is centred around Rockingham and Salcey Forests. The wet grassland and wetlands are focussed on the floodplain of the Middle Nene, whereas opportunities for semi-natural grassland are more spread throughout the area.

In addition to mapping individual opportunities, maps were also combined to highlight opportunities to enhance multiple services simultaneously. Planting woodland and trees, in particular, provides opportunities to deliver multiple benefits (such as reducing surface water runoff and improving air quality). Key locations for delivering these multiple benefits were around the edges of the major towns. Maps showing the combined opportunities for new semi-natural grasslands, and new wet grassland and wetlands were also produced.

Rebuilding biodiversity in Bedfordshire

In Bedfordshire, the Wildlife Trust and Bedfordshire and Luton Biodiversity Recording and Monitoring Centre advised on a Green Infrastructure Plan to provide the foundation for developing sustainable communities across the region.

With the county’s population set to grow significantly, the plan is part of an effort to ensure our environment is protected and sustained for current and future generations to enjoy. Linking with similar plans in adjacent counties, the plan is designed to help create sustainable communities, well served by greenspaces and green routes with access to the countryside on the doorstep.

It is a local demonstration of exactly the sort of work that can be called upon, and built upon, to create a nationwide Nature Recovery Network that is backed up by an Environment Act that ensures organisations and government are legally obliged to ensure it happens.

The vision for Bedford and Luton

The vision is to create a high quality green network across the county for people, places and wildlife, delivering a comprehensive strategic network of multi-functional greenspace and linking corridors.

A number of organisations joined forces to detail the county’s existing green assets and access routes and set out how these assets might be enhanced - and where the creation of new green spaces might best be targeted for the benefit of wildlife and people.

The plan is designed to help shape the county’s future, alongside and integrated with aspirations for housing, transport, employment and economic growth.

What's been mapped

As well as mapping existing green spaces ranging from Sites of Special Scientific Interest to hedgerows, ditches and disused railways, the map also shows a wide range of opportunities for action to enhance the following aspects of our green infrastructure:

  • Landscape – conservation and enhancement of important landscapes
  • Biodiversity – new habitat creation alongside enhancement and better linkages for wildlife
  • Historic environment – improved management, public access and interpretation of heritage assets
  • Access routes – improved connections across the county for walkers, cyclists and horseriders
  • Accessible greenspace – enhancement of key sites and greenspace creation in areas of deficit

Mapping natural capital and opportunities for habitat creation in Cambridgeshire

In 2019, a report on the habitats of Cambridge, commissioned by the Cambridgeshire and Peterborough Biodiversity Partnership of which the Wildlife Trust and the local Records Centre at CPERC are a part, was published. Using data from many existing sources of digital information, Natural Capital Solutions have produced a report that details the current status of known habitats in the area, and compares this with the information from surveys in the 1930s.

The report contains many maps of different habitats, including those that show potential habitat networks and opportunities which could be used to build a Nature Recovery Network in Cambridgeshire.

Next steps for a Nature Recovery Network

You can see from even these local examples that the way in which mapping has taken place, and the methodologies used, have been different across the country. In order to make sense of the national picture, the first step is to agree a national framework that sets out exactly what should be mapped, and identifies a common methodology, or ensures that methodologies used are complementary so that maps can easily be joined together to work at different scales. This should be agreed with input from existing local nature mapping initiatives, especially where these maps are already in use.  

A lot of this work has already been done, and in fact current planning policy already recommends that local planning authorities should map ecological networks. The difference now is that the Wildlife Trusts are calling for publication of these maps to be a legal requirement.

Once the maps are in place, legislation (a new Environment Act) can then ensure that all public bodies used them when making plans and taking significant decisions affecting the use of land. Sustainable development principles should strongly encourage individuals, businesses and organisations that have significant land management responsibilities to have regard to them, using them to avoid damaging the natural environment as well as capitalising on the opportunities to create and join up wildlife habitats that the maps present.

Take Action

Help us achieve a strong Environment Act

Making sure that there is a legal requirement for developing and publishing Nature Recovery Network Maps, as well as a requirement to consult them, means making sure we have a strong Environment Act that contains this legislation. We need our MPs to understand the need for this approach, and you can help.
