Analysis of seed numbers present in topsoils indicated that seeds of the most prevalent colonizers (e.g. Kochia scoparia, Setaria virdis, and Salsola collins) were not present in the topsoil upon respreading but rather appeared by immigration from the surrounding areas. Seed bank analysis was also undertaken on mined sites ranging in age of 2 to 6 years. As with the previous part of this study there was a poor correlation between the aboveground flora and the belowground seed composition.
