scope:

This guideline standardises the procedure for floristic mapping in the context of monitoring the environmental effects of GM plants. Standardisation ensures a high level of reproducibility and comparability of the results. This mapping method is used to record spontaneously occurring (non-cultivated) GM crops and their wild potential crossing partners and hybrid offspring resulting from crosses between GM crops and these partners. The aforementioned groups shall hereafter be collectively referred to as "plants to be mapped". Planted or intentionally sown GM crops are not included in the plants to be mapped. Provided that it has been correctly registered, details of sites where GM crops have been planted or intentionally sown can be obtained from the German genetically modified organisms (GMO) location register of the Federal Office of Consumer Protection and Food Safety (BVL; at http://www.bvl.bund.de on the GMO location register pages in the "Genetic Engineering" tab).
