Epping Forest, one of the most significant natural landscapes in London, lies within the northern and eastern edges of our borough. London’s largest open space, covering 2,400 hectares, Epping Forest is a valued green space for residents and popular visitor destination, receiving round 4.2 to 4.8 million visits every year. Epping Forest contains over 50,000 ancient trees, one of the largest concentrations in the country, and is home to some of Europe’s rarest species and habitats.
Special Area of Conservation (SAC) and Site of Special Scientific Interest (SSSIs) designations
The Epping Forest Special Area of Conservation (SAC) and Sites of Special Scientific Interest (SSSI), cover 1,600 hectares. A Special Area of Conservation (SAC) is a European designation given to areas of exceptional ecological value, as set out in Article 17 Habitats Directive 2019. The Epping Forest Special Area of Conservation (SAC) comprises wood-pasture with habitats of high nature conservation value, including ancient semi-natural woodland, old grassland plains, wet and dry heathland and scattered wetland.
Sites of Special Scientific Interest (SSSIs) are a conservation designation that protect areas that have been identified as being extremely valuable for their flora, fauna, physiological and geological features. They often contain important habitats such as grasslands, parkland, woodland, ancient woodland and ancient trees. The woodland is one of the largest continuous semi-natural blocks in the country, and the plains contain a variety of grasslands rarely found elsewhere in Essex or London. It also provides important habitats for invertebrates, amphibians and an exceptional breeding bird community.
Recreational pressures
The City of London Corporation became conservators of Epping Forest in 1878. As well as protecting its special nature conservation value, they are under a legal obligation to maintain public access for recreation and enjoyment. Whilst this is valuable to residents of Waltham Forest and the wider area, visits to the forest can put recreational pressures on its nature conservation value that need to be carefully managed. These include things like:
- trampling/wear, leading to soil compaction, vegetation wear, erosion and damage to veteran tree roots
- increased fire risk
- direct damage to veteran trees
- illegal harvesting of ecological features like fungi and deadwood. See City of London Article and Bylaws for more details
- disturbance to invertebrates and other wildlife
- spread of disease and alien plants
- eutrophication from dog fouling
- direct damage and vandalism of infrastructure.
How we are balancing protecting and enhancing the Forest with the need to build new homes in the Borough
There is a “Zone of Influence” of 6.2km from the forest boundary within which it is considered that building new homes could result in more visits to the Special Area of Conservation, and as a result, more recreational pressure. This Zone of Influence covers the whole of Waltham Forest and significant proportions of our neighbouring boroughs and local authorities.
At the same time, we also know that we need to deliver, on average, 1,800 new homes every year to meet the need for housing in the borough. We therefore need to put in place carefully balanced measures to avoid additional pressure on the forest as we build the new homes we need. In addition, new homes built within 400 metres of the Forest boundary are also considered likely to result in additional “urban effects”, which include things like cat predation, intrusive lighting, invasive species, fly tipping and vandalism. As a result, planning applications for new homes within 400m of the forest boundary may need further mitigation measures.
1. Habitat Regulations Assessment screening and appropriate assessment
All planning applications that would create one or more new home(s) must include a project level Habitat Regulations Screening and Appropriate Assessment. Visit the national HRA Requirements for more information. Applicants are asked to complete the appropriate template from the links below as fully as possible.
The type of Habitat Regulations Screening and Appropriate Assessment needed will depend on whether the development site falls within 400m boundary of the SAC or not. Please click below for a map showing the extent of the 400m boundary, and the different HRA forms.
2. Strategic Access Management and Monitoring Strategy
The borough-wide package of measures set out below has been developed with partner authorities who have residents travelling to the forest and has been agreed with Natural England. It applies to every planning application that will result in one or more new home being built anywhere in the borough, including those proposed under Prior Approval.
In order to mitigate recreational pressure in the forest, a Strategic Access Management and Monitoring Strategy (SAMMS) has been developed in partnership and agreement with neighbouring authorities that are also within the Zone of Influence. This sets out a fully costed set of measures to be delivered in the forest itself, ranging from interventions like repairing and improving paths and trackways to employing forest wardens to help visitors enjoy the forest safely.
All new homes built in the Zone of Influence will be required to make a financial contribution to the delivery of these measures. In Waltham Forest this equates to £650 for every new home built. This will be secured through Section 106 Legal Agreements associated with every planning consent we grant for one or more new homes, with the money passed directly to the Conservators of Epping Forest to fund the mitigations. Waltham Forest is a member of the Technical Oversight Group of partner local authorities who will oversee the investment in the forest and ensure these financial contributions are spent as agreed.
The SAMMS agreement was signed by all relevant authorities in January 2024 to come into effect on 16 January 2024. The new charge of £650 is effective from 1 April 2025 to 31 March 2026.
An update on the overall position in relation to SAMMS from Natural England can be viewed in the Update on the Epping Forest Strategic Solution – Recreational Pressure Zone of Influence and Strategic Access Management and Monitoring (SAMM) Agreement.
3. Suitable Alternative Natural Greenspaces
In order to mitigate increased recreational pressures in the forest, the Council will continue to provide attractive alternative visitor destinations across the borough by investing in our existing natural green spaces and places, and by opening those that do not currently benefit from public access. We call these Suitable Alternative Natural Greenspaces (SANGS).
Waltham Forest is a uniquely green borough, and we benefit from some of the best open spaces in London. Just like Epping Forest, these offer great opportunities for our local communities to visit and enjoy. You can read more about the proposals for further investment in our natural green spaces in the emerging Suitable Alternative Natural Greenspace strategy:
View the Green and Blue Infrastructure Maps on the Green and Blue Spaces Let's Talk Hub, to learn more about our SANGs projects and other green and blue infrastructure projects.
As with the Strategic Access Management and Monitoring Strategy, every new home that is delivered in the borough is expected to contribute to this investment. In most cases, we anticipate this investment being made through the Community Infrastructure Levy (CIL). This is a charge that we levy on new development in the borough to help deliver the infrastructure we need. It applies to most new buildings and the amount charged is based on the size and type of new floor space.
Certain types of development can apply for CIL relief, which means they don’t have to pay the charge. In these cases, we will negotiate a bespoke investment package and secure it through a Section 106 Legal agreement to ensure that all new homes delivered in the borough are making a fair and proportionate contribution to the delivery of Suitable Alternative Natural Greenspaces.

4. Additional measures for new homes within the 400 of the Epping Forest SAC boundary
Where a planning application is made for one or more new home(s) within 400m of the Epping Forest SAC boundary, they may be required to provide further mitigation to avoid Urban Effects. These will need to be agreed with Natural England and the Conservators of Epping Forest and will be negotiated through the planning process.
Strategic Access Management and Monitoring PLUS (SAMM+) measures are detailed in Policy 96 of the emerging Local Plan Part 2: Site Allocations. Site allocations within 400m of the Epping Forest SAC will be required to implement SAMM+ measures specific to the site in order to avoid or mitigate urban effects.
Local Plan Part 2 has been through Examination in Public (EiP) and therefore is afforded significant weight in line with NPPF paragraph 49.
A ‘toolbox’ of SAMM+ measures is set out in Policy 96 of Local Plan Part 2, from which appropriate measures to mitigate potential harm from urban effects should be selected at application stage on sites within 400m if the EFSAC, in conjunction with the preparation of a project level HRA.
The toolbox is not exhaustive, and other measures may also be agreed, dependent on the details of the specific proposals, with agreement of Natural England and the City of London Conservators.
Development proposals that are not site allocations may also be required to implement mitigation measures in conjunction with the SAMM+ approach.
