  1. Sow native grass and forbs

    A replicated, randomized, controlled study in 1995–1997 in a pasture in Iowa, USA (Jackson 1999) found that sowing grass and forb seeds increased plant species richness. The results of this study are not based on statistical analysis. Plant species richness was higher in areas where seeds were sown (8.6–9.4 species/plot) than in areas where no seeds were sown (3.5–5.0 species/plot). In May 1995, in order to remove any vegetation present, glyphosate herbicide was applied to four plots, each of which had an area of at least 500 m2. In June 1995, seeds of three native grass species and one native legume were sown by hand or using a seed drill in these four plots, while four other plots were not seeded. Cover of all plant species was monitored in five to eight 0.5-m2 quadrats in each plot from 1995–1997.
