Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Biological resource use fishing & harvesting aquatic resources - intentional use: lg scale happening now small area/few individuals (<10%) no or imperceptible deterioration low
Geological events earthquakes/tsunamis past (and unlikely to return) and no longer limiting whole area/population (>90%) no or imperceptible deterioration low
Human intrusions and disturbance recreational activities likely in long term (beyond 4 years) small area/few individuals (<10%) no or imperceptible deterioration low
Pollution domestic & urban waste water - sewage happening now some of area/population (10-49%) moderate to rapid deterioration high
Transportation and service corridors roads and railroads happening now small area/few individuals (<10%) no or imperceptible deterioration low

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Some of site covered (10-49%) A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
