Comoro Olive-pigeon Columba pollenii NT resident 1998 present A1, A2
Comoro Blue-pigeon Alectroenas sganzini NT resident 1998 present A2

yes unset good

Pressure (threats to the trigger species and/or their habitats)
Threat level 1 Threat level 2 Timing Scope Severity Result
Biological resource use hunting & collecting terrestrial animals - intentional use (species being assessed is the target) happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Biological resource use logging & wood harvesting - unintentional effects: large scale happening now whole area/population (>90%) very rapid to severe deterioration very high
Climate change and severe weather storms and floods happening now whole area/population (>90%) moderate to rapid deterioration very high
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
