A feasibility study comparing birds from organic and conventional (chemical) farms in Canada / Catherine A. Rogers, Kathryn E. Freemark.: CW69-5/137E-PDF
"The study reported here was conducted in 1989 to investigate the feasibility of comparing birds between organic and conventional (chemical) farms in Canada, as a novel approach for assessing these effects. Since then, more extensive field studies have been conducted in Ontario, Saskatchewan and Quebec. The current report provides the background information used to justify the implementation of and specific design for those studies. The preliminary findings reported here, that the use of chemical pesticides and/or fertilizers contribute to a reduction in the number and variety of farmland birds, has been corroborated by analyses of the more extensive sample from Ontario"--Abstract.
