List of nature reserves in the London Borough of Barnet

The London Borough of Barnet, on the northern outskirts of London, is mainly residential, but it has large areas of green space and farmland. The spread of suburban development into the countryside was halted by the designation of a statutory Green Belt around London after the Second World War, and almost one third of Barnet's area of 8,663 hectares (21,410 acres) is Green Belt. Without this control, Barnet would be very different today, and this list of nature reserves would be much shorter.[1]

Beech Hill Lake in Monken Hadley Common

Most of Barnet lies over London Clay, which is poor for agriculture, and open land is mainly used for activities such as horse grazing, playing fields, parks and golf courses. Features of the traditional agricultural landscape have survived, such as old hedgerows, ancient trees and areas of herb-rich grassland. Some hay meadows have a large diversity of wild flowers, and the London Ecology Unit (LEU)[lower-alpha 1] described them as one of Barnet's most important ecological assets.[4]

Barnet has large areas with designations intended to protect them from "inappropriate development", and to "provide the strongest protection for the preservation of Barnet's green and natural open spaces". As well as 2,466 hectares (6,090 acres) of Green Belt, Barnet has another 690 hectares (1,700 acres) of Metropolitan Open Land, which receive a similar level of protection. Watling Chase Community Forest[lower-alpha 2] covers 72 square miles (190 km2), extending north and west from Totteridge into south Hertfordshire.[6]

In 1992 Barnet Council commissioned the LEU to carry out a survey of wildlife habitats in the borough, which looked at green sites covering 4,055 hectares (10,020 acres), 45% of the borough. In 1997 the LEU published Nature Conservation in Barnet, which described 67 Sites of Importance for Nature Conservation (SINCs).[7][8] This formed the basis of Barnet's nature conservation policies in its 2006 Unitary Development Plan, designated as "a material planning consideration" to be used as "non-statutory guidance".[9] The table below lists SINCs described in Nature Conservation in Barnet.[10][lower-alpha 3] SINCs do not have statutory protection, but some sites are also wholly or partly designated as Sites of Special Scientific Interest[lower-alpha 4] or local nature reserves,[lower-alpha 5] which do have statutory protection.[18] According to a report of the Department for Environment, Food and Rural Affairs, 39% of Barnet's SINCs were "in positive conservation management" in 2009–10. Barnet Council did not supply figures for 2010–11, 2011–12 or 2012–13.[19]

Notes
  1. The London Ecology Unit was established to provide advice to London boroughs following the abolition of the Greater London Council in 1986. In 2000 it was abolished and absorbed into the Greater London Authority.[2][3]
  2. Community Forests' objects include revitalising derelict land, providing new leisure facilities, preparing for climate change and increasing biodiversity.[5]
  3. Nature Conservation in Barnet lists 67 sites, but only 66 are shown in this table because Grahame Park SINC no longer exists. It has been re-modelled and renamed Heybourne Park.[11][12] The sites were listed on the Mayor of London's Wildweb website, which was taken down in December 2010. In spring 2012 it was replaced by a new site hosted by Greenspace Information for Greater London (GiGL), London's environmental record centre.[13] This new website covers most SINCs, but others are left out, some which are not publicly accessible and others in error. Wildweb included maps of every site, but Nature Conservation in Barnet only has maps of the most important ones, the 'Sites of Metropolitan Importance'. GiGL has maps for the sites it lists,[14] but the only map for the other sites is the map of the whole borough inside the back cover of Nature Conservation in Barnet. The list of SINCs in Nature Conservation in Barnet has not been updated and is still the basis for GiGL's database.
  4. There are 36 Sites of Special Scientific Interest in Greater London. The only one in Barnet is Brent Reservoir.[15] Darland's Lake was formerly an SSSI but the designation was withdrawn when it was found that the rare fritillaries on the site had probably been planted.[16]
  5. Natural England lists 141 local nature reserves in Greater London. Seven of these are in Barnet, but two of these are divided into separate SINCs. Scratchwood and Moat Mount is one LNR but two SINCs, and the same applies to Coppett's Wood and Glebelands. Nine SINCs are thus also LNRs.[17]
  6. The figures for area are taken from Nature Conservation in Barnet.
  7. The grid references are taken from Nature Conservation in Barnet. Click on the grid reference and then select a map to see the location of the reserve.
  8. Brent Reservoir is partly in the London Borough of Brent, and 46 hectares out of the total of 96 is in Barnet.
  9. Hampstead Heath SINC is composed of the main Heath in the London Borough of Camden and Hampstead Heath Extension and Golders Hill Park in Barnet. 46 hectares is in Barnet out of the total of 329.
