Variable General Info
Site (restored landfill/paired reference) ?Comment:Nine restored landfill (LF) sites were selected from the pool of 42 based on minimum size of the site and sites which have been restored for at least 4 years. The mean size (±standard deviation) of restored landfill sites was 13.98 ± 10.45 ha. In order to provide a comparison, the closest grassland sites of recognised conservation value (being designated as either local nature reserves (LNRs) or sites of special scientific interest (SSSI)) to the restored landfill sites were selected. |
