  1. Create uncultivated margins around intensive arable or pasture fields for birds

    A replicated study in southern Quebec, Canada, in July 1995 (Jobin et al. 2001), found that herbaceous borders around arable fields held significantly fewer individuals and species than either hedges or trees planted as windbreaks (19 species found in 17 herbaceous borders, at 19 birds/ha vs. 25 species at 51 birds/ha for 17 windbreaks and 39 species at 57 birds/ha for 27 hedges). Differences were significant, even when adjusting for different sample sizes.
