Description of the 18 scenarios simulated to predict their effects on the level of avian diversity in the 22 Sardinian wetlands under study.
| Scenario Type | Code | Conditionalization | Outcome |
|---|---|---|---|
| Baseline scenario | (a) | none | the baseline level of avian diversity |
| Worst-case scenario | (b) | tourism pressure = 3 | the expected level of avian diversity if tourism pressure becomes widespread in all wetlands |
| Worst-case scenario | (c) | water salinity = 3 | the expected level of avian diversity if water salinity becomes widespread in all wetlands |
| Worst-case scenario | (d) | water discharges = 2 | the expected level of avian diversity if water discharges become scattered in all wetlands |
| Worst-case scenario | (e) | anthropization = 2 | the expected level of avian diversity if anthropization becomes scattered in all wetlands |
| Worst-case scenario | (f) | water level = 11 | the expected level of avian diversity if water level exceeds 100 cm in all wetlands |
| Worst-case scenario | (g) | water diversions = 0 | the expected level of avian diversity if water diversions become null in all wetlands |
| Worst-case scenario | (h) | scenarios b–g together | the expected level of avian diversity if scenarios from b to g occur all together |
| Best-case scenario | (i) | tourism pressure = 0 | the expected level of avian diversity if tourism pressure becomes null in all wetlands |
| Best-case scenario | (j) | water salinity = 0 | the expected level of avian diversity if water salinity becomes null in all wetlands |
| Best-case scenario | (k) | water discharges = 0 | the expected level of avian diversity if water discharges become null in all wetlands |
| Best-case scenario | (l) | anthropization = 0 | the expected level of avian diversity if anthropization becomes null in all wetlands |
| Best-case scenario | (m) | water level = 3 | the expected level of avian diversity if water level is between 20 and 30 cm in all wetlands |
| Best-case scenario | (n) | water diversions = 3 | the expected level of avian diversity if water diversions become widespread in all wetlands |
| Best-case scenario | (o) | scenarios i–n together | the expected level of avian diversity if scenarios from i
to n occur all together |
| Mixed scenario | (p) | same as scenario h but tourism pressure = 0 | the expected level of avian diversity if all conditions deteriorate except for tourism pressure that becomes null |
| Mixed scenario | (q) | same as scenario h but water salinity = 0 | the expected level of avian diversity if all conditions deteriorate except for water salinity that becomes null |
| Mixed scenario | (r) | same as scenario h but water discharges = 0 | the expected level of avian diversity if all conditions deteriorate except for water discharges that become null |
