Soil seed banks on study sites of the SRP.

Within this project the soil seedbank of long living seeds of the herbaceous vegetation and shrubs will be studied on selected sites within the Special Research Programm Forest Ecosystem Regeneration. By doing so it should be possible to evaluate risks of weeds, which are likely to limit the success of conversions of secondary spruce stands to mixed species stands. It is hypothesized that species composition affects soil depth, in which living seeds exist, and seed mortality.
