  1. Sow native grass and forbs

    A replicated, randomized, paired, controlled, before-and-after study on a road verge in Norway (Rydgren et al. 2010) found that sowing grass and forb seeds did not alter vegetation cover or similarity of the plant community to intact grasslands, but did increase plant species richness. For three of three years, vegetation cover in areas where seeds were sown (32–71%) did not differ significantly from areas where no seeds were sown (27–57%). The same pattern was seen for plant community similarity to a nearby intact grassland (data reported as Bray-Curtis dissimilarity index). However, plant species richness was higher in areas where seeds were sown (10–11 species/plot) than areas where no seeds were sown (8–9 species/plot). In September 2004, five blocks containing six 0.5 × 0.5 m plots were established. In each block, seeds of 17 species from nearby intact grasslands was sown in three plots and no seeds were sown in three plots. In each plot, vegetation cover of each species was estimated in sixteen 12.5 × 12.5 cm quadrats in July/August 2005–2007.
