For the BRS Weed Risk Assessment (WRA) system, a non-GE (baseline) WRA of a plant taxon is prepared first, to serve as a basis for comparative assessment of weed risk between a GE plant and its non-GE counterpart. Risk assessors collect, document, and analyze objective, evidence-based information about the biology of the baseline and GE plants, as well as their impacts, if any, to agricultural plants and agriculturally important natural resources.  See our Draft WRA Work Instructions and example WRAs listed below.
