Restore/create species-rich, semi-natural grassland
A randomized, replicated and controlled trial in 1999-2003 of restoration methods at two sites in the UK (Pywell et al. 2007) found that turf removal followed by seed addition was the most effective means of increasing plant diversity. Multiple harrowing was moderately effective and was enhanced by applying snail/slug pesticide and sowing yellow rattle Rhinanthus minor (which reduced competition from grasses). Grazing, slot-seeding and inoculation with soil microbial communities from species-rich grasslands did not increase botanical diversity, and different grazing management regimes had little impact. Thirteen treatments were applied to 15 x 15 m plots at sites in Devon and Buckinghamshire, with eight replicates of each treatment. All treatments were managed with a single July hay cut.
