The survival of viable seeds in stored topsoil from opencast coal workings and its implications for site restoration

The viable seed populations of two topsoil stores, three months and four years old, were estimated. Samples were taken for incubation from the surface and 1 and 2 m depth in each case. The methods used gave a good indication of species composition of the viable seed banks. Analysis revealed signific...

Description
Summary:The viable seed populations of two topsoil stores, three months and four years old, were estimated. Samples were taken for incubation from the surface and 1 and 2 m depth in each case. The methods used gave a good indication of species composition of the viable seed banks. Analysis revealed significant effects of age and depth on total seed numbers, as well as an interaction between the two. The results are discussed in relation to conditions in the stores, with implications for subsequent re-vegetation of the reinstated topsoil.
