IBA Monitoring

2008 high not assessed medium
Good - based on reliable and complete / representative data

Climate change and severe weather storms and floods likely in short term (within 4 years) whole area/population (>90%) slow but significant deterioration high
Human intrusions and disturbance recreational activities likely in long term (beyond 4 years) small area/few individuals (<10%) slow but significant deterioration low

Most of site (50-90%) covered (including the most critical parts for important bird species)  A management plan exists but it is out of date or not comprehensive  Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity  medium
