AnytimeAbout the reserve
Glades and open grassland within the reserve have attracted more than 12 species of butterfly including the increasingly scarce grayling and dingy skipper. The steep river banks provide nesting habitat for a small colony of sand martins and give excellent views of common and grey seals which prey on salmon preparing to negotiate a passage through the Tees Barrage.
The Teesside Development Corporation acquired Maze Park in the late 1980s. Reclamation of the extensive Head Wrightson works in Thornaby, which preceded the construction of the Teesdale business park, released a great deal of waste substrate and soils. The landscaping of these waste materials formed the mounds which dominate Maze Park today.
The central mound is flat-topped and its plateau consists of the characteristic steelworks slag materials, presumably originating from the Thornaby blast furnace; one of the first of such structures on Teesside. The steelworks waste is lime-rich, low in nutrients and free-draining and its nearest natural equivalent would be chalk grasslands or base-rich sand dunes systems. Typically they contain an abundance of herb species including yellow wort, black medick, common centaury and bird’s-foot trefoil.
These grasslands form an open sward with patches of bare ground and support two species of butterfly that have suffered significant declines across Britain – the grayling and dingy skipper. They also provide excellent habitat for bird species in national decline such as the grey partridge and skylark.
In 1998, the Trust took over the site. We are lucky to have an opportunity to protect such a classic example of Teesside slag grassland, with its rich biodiversity and links with the area’s industrial heritage. As well as planting 6 hectares of woodland, the Trust constructed a network of surfaced paths to allow visitors to enjoy every part of Maze Park.
