  1. Sow native grass and forbs

    A replicated, randomized, paired, controlled study in 1999–2001 on former logging roads and agricultural areas in British Colombia, Canada (Burton et al. 2006) found that sowing native grass and forb seeds increased the total cover of sown plant species. These results are not based on statistical analyses. During two years after sowing, total cover of sown plant species was higher in areas where seeds were sown (4–62%) than in areas where no seeds were sown (0–10%). In autumn 1999, six blocks were established each containing twelve 2.5 × 2.5 m plots. All plots were cleared of rocks and vegetation and tilled to a depth of 12 cm. Ten plots in each block were sown with seeds of six native species at a rate of 375–6,000 seeds/m2, and two plots were not sown with seeds. In September 2000 and August 2001, vegetation cover was estimated in three randomly placed 0.5 × 0.5 m quadrats/plot.
