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? |
<_2 <_2 <_2 >_3 |
- reject - reject
- reject - approve |
| Review Level II:
5. Would the organism be unable to establish a self-sustaining population in the range of habitats that would be available? |
>_3 |
- approve |
| Review Level III:
6. Would the organism have mostly positive ecological impacts? 7. Would most consequences of the introduction be beneficial to humans? |
<_ 2 <_2 |
- reject - reject |
| Review level IV:
8. Is the data base adequate to develop complete species synopsis? 9. Does the database indicate desirability for introduction? 10. Would benefits exceed risks? |
<3 <_2 <_2 |
- conduct detailed literature review (1*). - to next question - reject - reject |
1* Thereafter next step question 9
2* Research focused on potential impact on indegenious species and habitats. Thereafter question 10.
