Saving the small things that run the planet
Wedged between the Mar Dyke Valley and Lakeside Retail Park, the former Arena Essex Raceway is a wildlife haven.
While the dust may have settled from stock car and speedway bikes racing across the finish line, nature continues to thrive on the former Arena Essex Raceway. Its complex history has produced a unique mosaic of brownfield features, calcareous grassland, flowery Thames Terrace Grassland, bare ground, scrub and young woodland, earning it Local Wildlife Site status.

Update October 2025: Will you help us to stand up for wildlife and climate and urge Thurrock Council to refuse planning permission for the Google led Thurrock Data Centre at Arena Essex? Buglife, Essex Wildlife Trust, Foxglove and Essex Field Club are encouraging their supporters to submit comments to Thurrock Council by the deadline of Saturday 8 November.

This hidden secret in Thurrock has no public rights of way, but much of the site has been used for many years for fishing and informal walking and cycling. It has also been found by wildlife in an increasingly developed landscape. Its 52 hectares are home to hundreds of species of invertebrates, including Brown-banded Carder Bee (Bombus humilis), Five-banded Weevil-wasp (Cerceris quinquefasciata) and the Dingy Skipper butterfly (Erynnis tages) – with many more to be found – as well as rare plants such as Endangered Broad-leaved Cudweed (Filago pyramidata) and birds such as Red Listed Nightingale (Luscinia megarhynchos). The nationally important invertebrate communities found at the site have been known for years, making it a core part of the Thames Estuary North Important Invertebrate Area.
However, the chequered flag was waved on the Raceway in 2018 and its future as a wildlife haven is at risk from a new data centre campus for Google. The Google-associated ‘Global Infrastructure UK Limited’ plans would lead to over 80% of its precious Open Mosaic Habitat on Previously Developed Land being lost, including areas of irreplaceable Thames Terrace Grasslands – a unique habitat that Natural England says now limited to just tens of hectares. Meanwhile, Google claims in its 2025 Sustainability Report of “Cultivating nature on our campuses” and “rebuilding nature in the very places it’s been paved over”.
The loss of Arena Essex would add it to a growing list of important Local Wildlife Sites for invertebrates that have been lost in Thurrock or will imminently be lost- threatening the long-term future of the nationally important invertebrate populations of the Thames Estuary. Key sites in this once extensive network have been destroyed for sprawling port developments, industrial expansion, inappropriate restoration schemes and housing development. Meanwhile, more sites will be lost in the coming years following the approval of the Lower Thames Crossing and are threatened by yet more port expansion as part of Tilbury 3.
Buglife is calling on Google to search for the spirit displayed in their own sustainability report, reverse course and spare this unique wildlife site and for Thurrock Council to show an urgent commitment to nature recovery and refuse this destructive application.
