Developer-funded archaeology work tends to emphasise urban, brownfield sites. In the last decade the investigation of industrial production sites has been driven by such urban redevelopment. Sites investigated in this way include metal processing and manufacturing sites, especially textile sites. Sometimes this has included industrial period extractive sites (coal, copper, and limestone), though these have also been investigated through HLF community projects and through landscape management initiatives in the Lake District National Park and elsewhere. More generalised landscape surveys of surviving extractive and manufacturing sites have been undertaken by the Association for Industrial Archaeology for Lancashire (Nevell & George 2007) and for Cheshire (Nevell & George 2017). Both studies noted the high rate of destruction of such upstanding remains when compared to an earlier landscape survey from 1981 (Ashmore 1981).
