| Abstract: | Abstract. Experimental plots in grass heath, previously subjected to various sod cutting treatments, contained a seed store of ericoid dwarf shrubs, but seeds of grasses of the former grass heath were not found. The density of emerging dwarf-shrub seedlings in the plots was determined mainly by soil moisture, but with density of seeds stored in the soil and soil acidity as modifying factors. It is concluded that the restoration of a dwarf-shrub heathby sod cutting is relatively successful, as compared to other measures, because the grass seeds become obsolete. |
