  1. Sow native grass and forbs

    A replicated, randomized, paired, controlled study in 2003–2006 in eight prairie restoration sites in Iowa, USA (Wilsey & Martin 2015) found that sowing grass and forb species did not alter plant species richness. Plant species richness did not differ significantly between areas where seeds were sown (10.7 species/plot) and areas where seeds were not sown (9.8 species/plot). In each site, four 1 x 1 m plots were sown with seeds and two plots were not seeded. All plots were burned in April 2005. In 2003–2006, a 1 x 0.4 m quadrat was placed in each plot and species richness estimated by eye.
