Site of Importance for Nature Conservation
The Harringay Stadium Slopes was designated a Site of Importance for Nature Conservation (SINC) in 2002. The citation has the following to say about the area:
Tree Preservation Orders
The importance of the trees at the site was recognised as far back as 1979 when the first Tree Preservation Order (TPO) was made on 13 sycamore trees in the area to the north of what is now 85 and 87 Hermitage Road. This TPO is currently listed under numbers TPO/2014/1752 and TPO/2014/2252.
More recently an additional TPO, number TPO/2020/0001, was applied for to protect some of the trees further to the west. Update, this TPO has now been granted – see this letter from the council.
Recognition by Haringey Council
Haringey Council is committed to preserving the SINCs in the borough, with this statement appearing in the latest Strategic Policy:
Ecological Corridors are relatively continuous areas of green space running through built up areas that allow the movement of plants and animals to other areas and habitats. The Harringay Stadium Slopes forms an Ecological Corridor linking to the Tottenham Railsides SINC.
In planning documentation adopted in July 2017 Haringey Council identified the Harringay Stadium Slopes as a part of a future extended ecological corridore linking all the way through to Finsbury Park.
The London Plan
The London Plan is the overall strategic plan for London, setting out an integrated economic, environmental, transport and social framework for the development of London over the next 20–25 years. This Plan recognises London’s most valuable and special places for wildlife as Sites of Importance for Nature Conservation (SINCs).
Key Performance Indicator #18 in the London Plan is the protection of biodiversity habitat, measured by “No net loss of designated Sites of Importance for Nature Conservation”.
