Reduce tillage
A replicated, controlled study from June-July in 1996-1997 in 37 conservation tillage, 40 organic, 38 conventional and 31 wild (control) sites in both upland and wetland areas of crop farms (75% wheat) in Saskatchewan, Canada (Shutler et al. 2000), found that bird diversity and abundance were highest overall in wild areas compared to farmed areas, highest in conservation tillage farms in upland areas and in organic farms in wetland areas. In upland areas, of 37 species recorded, one was more abundant on farms, four more abundant in wild areas while the rest showed no distinct preference. Conservation tillage wetlands had similar bird communities to conventional wetland farms. Clusters of four treatments were located within a 25 km radius of one another. Fixed-radius (100 m) point-count surveys were used to survey twice per year.
