IBA conservation assessment
Year of assessment State Pressure Response
2009 not assessed high low
Whole site assessed? State assessed by Accuracy of information
yes unset poor

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Invasive and other problematic species and genes happening now majority/most of area/population (50-90%) slow but significant deterioration high
Natural system modifications likely in short term (within 4 years) some of area/population (10-49%) very rapid to severe deterioration high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas Management plan Other action Result
Some of site covered (10-49%) No management plan exists but the management planning process has begun Very little or no conservation action taking place low
