Overview

The habitat selection, territory density, nesting success and diet of Skylarks breeding on one organic and one conventional farm in north Suffolk were investigated as a pilot study to examine the impact of organic farming practices on Skylark breeding populations. Territory density was higher on the organic than on the conventional farm, and this difference could be explained largely by differences between the two farms in field size, boundary characteristics, and cropping. Rotational and five-year set-aside, and organic cereals were the most attractive field types to Skylarks.
