Review and decision model recommending the outcome of mean scores for opinions of the reveiw panel to various questions or issues posed in the opinionairre (after Bartley 1993)

Review Level Opinionairre value Decision
Review Level I:

1. Is the need valid and are native species available that could serve the stated need?



2. Is the organism safe from over-expolitation in its native range?



3. Are safeguards adequate to gurad against importation of disease/parasites?



4. Would the introduction be limited to closed systems?
