  1. Sow grass seeds

    A replicated, controlled study in 2004–2006 in a former arable field in Gauteng province, South Africa (Oudtshoorn et al. 2011) found that sowing grass seeds increased the abundance of sown species and reduced the abundance of unsown species. After two years, in two comparisons the density of sown species was higher in areas where soil was disturbed and grass seeds were sown (35–80 plants/m2) than in areas where soil was disturbed but no grass seeds were sown (2 plants/m2). The opposite was true for plants whose seed was not sown (disturbed and sown: 51–122 plants/m2; disturbed and unsown 250 plants/m2). In 2004, eight 20 × 10 m plots were ploughed and sown with seeds of five grass species. Eight plots were disturbed with a single toothed ripper and sown with seeds of five grass species, and four plots were ploughed or disturbed with a ripper and not sown with seeds. In March 2005 and 2006, eight 1-m2 quadrats were placed in each plot and the number of plants counted.
