The issue we're facing
Local Plans guide where new homes, employment and infrastructure are built across the district over the coming years. Sevenoaks District Council's recently published Local Plan Regulation 19 proposes allocating land immediately north to Sevenoaks Wildlife Reserve for major housing development. The proposed allocated site, referred to as Land North of Sevenoaks, West of Otford Road (site reference ST4-7), would deliver 1,500 new homes, provision for 12 gypsy and traveller pitches and accommodate a new local community and leisure centre and associated infrastructure.
Whilst we recognise the need for new housing, we do not believe development should come at the expense of nature. We strongly advocate for the right development in the right place.
Our main concerns:
Threat to Sevenoaks Wildlife Reserve
Sevenoaks Wildlife Reserve is a vital habitat for wildlife. At its heart lies the Sevenoaks Gravel Pit Site of Special Scientific Interest (SSSI), a nationally significant site supporting over 2,000 species, including protected and red-listed birds, alongside rich botanical and invertebrate life. The River Darent, a rare and vulnerable chalk stream, flows through the reserve, making it a place of exceptional ecological value.
The area of land north of the reserve is the last substantial area of open countryside connecting the reserve to the wider landscape. Kent Wildlife Trust is concerned that large-scale development on this land would significantly reduce this connectivity, leaving the reserve enclosed by development and isolated from the surrounding countryside. Protecting and strengthening these connections is vital to creating a resilient landscape where wildlife can thrive for future generations.
Impacts on the River Darent
The River Darent, one of Kent’s rare and environmentally important chalk streams, runs through the proposed allocated sites. Chalk streams are one of the world's rarest freshwater habitats, with around 85% found in England, most of them in the south-east. They support an exceptional diversity of wildlife and are often described as England's equivalent of tropical rainforests because of their global importance and rarity.
Significant parts of the proposed allocated site lie within both Flood Zone 3a, which refers to land with a high probability of annual flooding and Flood Zone 3b, which is land that is considered a functional floodplain, where water naturally flows and is stored during times of flooding.
Large-scale development could increase polluted runoff, sediment and contaminants entering the River Darent, damaging water quality and the wildlife that depends on this important chalk stream. Development within and alongside the floodplain could also reduce the landscape's ability to naturally store and slow floodwater, increasing flood risk downstream and placing additional pressures on wildlife and communities.
Increased pressure on wildlife
Sevenoaks Wildlife Reserve is enjoyed by thousands of people every year, and we firmly believe everyone should have the opportunity to access nature.
However, the current concept masterplan for the proposed allocated sites includes new access into the reserve from the north, directly linking it to a development of 1,500 homes. This could bring over 5,000 additional residents within easy walking distance to the reserve, significantly increasing recreational pressure on sensitive habitats.
At present, visitors enter through the Visitor Centre, where Kent Wildlife Trust can provide information and help manage activities that could harm wildlife, such as dog walking and cycling, which are not permitted. A new, unmanaged entrance would make this much more difficult and could increase disturbance to wildlife, littering and anti-social behaviour.
Make your voice count
Between 23rd July and 17th September, Sevenoaks District Council is consulting on its Local Plan Regulation 19. This consultation is the final opportunity for residents to comment on the Draft Local Plan before it is finalised.
We need your help to Preserve Sevenoaks Wildlife Reserve. By taking part in the Regulation 19 consultation, you can speak up for nature and help protect this nationally important site.
More resources
You can download and read the Draft Local Plan here.
There are two ways to respond to the consultation. You can complete the online consultation form available on Sevenoaks District Council's consultation webpage or submit a more detailed written response by email to [email protected]
To help you write a more detailed response to the consultation, you can read our guidance document on how to respond to a Local Plan Regulation 19 consultation here (COMING SOON).
Help us develop an alternative vision
We believe there is a better future for this landscape.
Rather than surrounding Sevenoaks Wildlife Reserve with housing, we want to see an alternative vision that:
- protects the Wildlife Reserve and the River Darent;
- restores habitats and strengthens ecological networks;
- improves climate resilience; and
- delivers greater benefits to local communities for future generations.
Nature should not simply be left with isolated pockets of habitat; it should be given the space to recover and thrive.
We want to develop an alternative vision for the future of this landscape, and we'd like your help. Our short questionnaire asks what you value most about Sevenoaks Wildlife Reserve and the surrounding area, your views on the proposed development, and what you would like to see instead.
Your responses will help shape our campaign to Preserve Sevenoaks Wildlife Reserve and inform the development of an alternative vision for this special place.
