Eample AHPIS WRA Weed Risk Assessments for Acalypha australis, Althaea armeniaca, Hakea sericea, Hippophae rhamnoides, and Solanum seaforthianum

In this document, we assess the weed risk potential of five plant species using Plant
Protection and Quarantine’s (PPQ) weed risk assessment guidelines (PPQ, 2009).
The weed risk assessment (WRA) process and the predictive model utilized are
consistent with the general guidance provided by international and North American
standards for risk assessment (IPPC, 2009: ISPM Nos. 2 and 11; NAPPO, 2008:
RSPM No. 32). The weed risk assessments below contain information relevant for
the initiation, species categorization, and risk assessment phases. These phases correspond to Stage 1 (initiation) and Stage 2 (risk assessment) of risk analysis (IPPC, 2009: ISPM No. 2).
