  1. Sow native grass and forbs

    A replicated, randomized, paired, controlled study in 2003–2004 in a former hay field in Ohio, USA (Fraser & Madson 2008) found that sowing native grass and forb seeds increased plant species richness. Average plant species richness was higher in plots where seeds were sown (7–9 species/plot) than in plots where seeds were not sown (4–5 species/plot). In March 2003, in each of six blocks, seeds of 20 native, wet meadow grass and forb species were sown at a rate of 150 seeds/species in each of two 1 x 1 m plots, while two other plots were left unseeded. Seeds were collected from nearby fields or from cultivated plants. In August 2004, vegetation in the central 0.25 m2 of each plot was harvested and used to identify plant species.
