the harmful organism, which is established in one or more other parts of the Union, is not present in that area despite the environmental conditions in the protected zone being favourable for its establishment;
there is a danger that certain harmful organism will establish in that area, given propitious ecological conditions, for particular crops, despite the fact that the organism is not endemic or established in the Union.
