The monitoring and surveillance of genetically modified higher plants (GMHP) is an area that is still lacking an established international monitoring program. This volume presents ideas and suggestions by focusing on procedures in composing such a program and methods for detection of transgene dispersal and of environmental effects when GM plants are cultivated. Objectives and procedures for monitoring and surveying present and new types of GM plants are described, including herbicide tolerance, insect resistance and changed agronomic performance. Other issues covered in this book include: detection of GM plant dispersal and hybridisation; agricultural use and large scale effects; habitat selection and community invasibility; baseline definition and the time perspective; effects on ecosystems, vegetation and organism groups; sampling designs; data analysis and relevant statistical methods. In a final chapter, conclusions and recommendations are presented... Written for: Researchers, legislators, administrators Keywords: Crop Science Plant Genetics Transgenetics
