Convert to organic farming Bee Conservation

In the same study, the total number of bee species was higher under organic farming whether you considered the number found at individual sites, the total number found in each region or the total for the entire study (Clough et al. 2007). Diversity between sites as well as within sites was greater for organic fields than for conventional fields. This means bee diversity improved under organic wheat farming at the larger landscape level, as well as the local level.
