1.14Pest risk assessment conclusion

The unrestricted risk posed by Aspidiella hartii is estimated to exceed Australia’s ALOP. Therefore, management measures for this pest are required to reduce the quarantine risk.

The unrestricted risk of the other pests assessed achieves Australia’s ALOP and therefore risk management measures are not required.

The results of the risk estimates are summarised in Table 4.2. The rationale for each value of the pest risk assessment, summarised in this table, is described in the relevant sections above.

The proposed pest risk management measures are discussed in Section 5.
