Wasteland 4 – Fourth in a series of pictures of vegetation apparently growing naturally on wasteland and contributing to the biodiversity of the habitat from the side of Pipers Walk on the Waterfront in Swansea, South Wales, 19 June 2021.
Lake et al (2015) note that brownfield or wasteland sites could possibly have a highly unusual chemical composition from fuel ash and waste products due to an industrial use of the location in the past. This means that the pH of the thin soils may vary greatly across the site. That in turn would affect its suitability for a wide range of vegetational types. It is difficult to know what formerly stood in this particular dockland location before demolition but certainly a legacy of coal ash or oil could be expected, or anything else that would have been imported or exported. The coarse skeletal soil is considered ‘crucial in maintaining the habitat in an early-successional stage, an element that is rare in the lowlands’.
