§ Mr. Meacher
There is no readily available comprehensive list of all this work, though the more relevant papers are referenced in various DETR/Advisory Committee on Releases to the Environment publications lodged in the Library or placed on the DETR internet site. Research into details of all the processes is continuing,108W but mainly in Universities and relevant research institutes. The primary aim of the farm-scale evaluations is to investigate the impacts on wildlife populations and biodiversity in growing these crops on the field scale.
