A green oasis created by intersecting railway lines, saved from development and managed for wildlife and people
This wet woodland nature reserve was saved from development in the early 1980s and then enhanced by the creation of ponds and acid grassland areas.
Birds and small mammals take advantage of the sheltered birch and willow while walkways and footpaths help guide visitors around this wild oasis in Chiswick.

History of Gunnersbury Triangle
Abandoned allotments on railway land which had grown into woodland were at risk of development in 1981. But a campaign led by local people, supported by London Wildlife Trust and the (former) Greater London Council, ensured the area between the railway tracks was protected at a landmark planning inquiry in 1983. The land was given to Hounslow Council, and the Trust invited to manage it as a nature reserve. After work to make it more accessible for visitors, the site opened to the public in 1985. Both Hounslow and Ealing councils, on whose boundary the site sits, later designated the Triangle as a Local Nature Reserve.
