The taxonomic identity of the pest shall be defined at species level or, alternatively, a higher or lower taxonomic level, where that taxonomic level is scientifically appropriate based on its virulence, host range or vector relationships.

4. If it is concluded, on the basis of a risk assessment, that the plant, plant product or other object originating in the third country, group of third countries or specific area of the third country concerned referred to in paragraph 2, on the taxonomic level as listed in the implementing act provided for in paragraph 3 or below that level, does not pose a risk of an unacceptable level by its likelihood to host a Union quarantine pest, the Commission shall adopt an implementing act removing that plant, plant product or other object from the list referred to in that paragraph for the third countries concerned.

3. The Commission shall adopt implementing acts provisionally listing at the appropriate taxonomic level, pending the risk assessment referred to in paragraph 4, the high-risk plants, plant products or other objects referred to in paragraph 1 and, where appropriate, the third countries, groups of third countries or specific areas of third countries concerned.

In particular, it concluded, that due to the complexity of the taxonomy as well as the lack of current evidence concerning which species are susceptible to Bsal, rules at the level of the taxonomic order are likely to be both more effective and more feasible than species-specific rules.
