Appendix ASpecies of concern

771Table provides a summary of the 56 SOC that the Australian Government proposes to manage for under the proposed Australian Biofouling Management Requirements. Specific data for each of the species listed below that was used in analysis are provided in Appendix A of the Species Biofouling Risk Assessment which is available online at www.marinepests.gov.au. The Species Datasheets include: inoculation likelihood, biofouling association rank, transport pressure rank, physiological tolerances, potential impacts (environmental, economic, social/cultural, human health) and references.

Table : List of 56 species with risk rankings of extreme (E), high (H) or moderate (M) in at least one core value category and in at least one voyage duration from Hewitt, et al., 2011c

Note: For the risk assessment M is associated the numerical value of 1, H is assigned to numerical value 3, E is assigned to numerical value 5 (Hewitt et al., 2010).

772Some States and Territories currently have powers that enable them to control for biofouling species that are not currently present in Australia, which are not included in the list of 56 SOC (Table ). These species include Perna canaliculus, Hemigrapsus penicillatus and Ensis directus.

P. canaliculus was not included because it is not known to have successfully invaded and established itself anywhere in the world, despite the previous detection of several individuals in SA, which were successfully eradicated.

H. pencillatus was not included due to lack of documented impacts due largely to relatively recent date of invasions resulting in risk rankings less than moderate for any individual core value.

E. directus was not included due to limited global distribution and limited information on inferred or demonstrable impacts resulting in risk rankings less than moderate for any individual core value (Hewitt et al., 2011c).
