IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2007 medium unfavourable low
Was the whole site covered? Yes State assessed by Population
Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Energy production and mining renewable energy likely in short term (within 4 years) small area/few individuals (<10%) moderate to rapid deterioration low
Natural system modifications dams & water management/use - abstraction of ground water (agricultural use) happening now some of area/population (10-49%) slow but significant deterioration medium
Pollution domestic & urban waste water - sewage happening now small area/few individuals (<10%) slow but significant deterioration low
Transportation and service corridors roads and railroads likely in short term (within 4 years) small area/few individuals (<10%) moderate to rapid deterioration low

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
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site (50-90%) covered (including the most critical parts for important bird species) A management plan exists but it is out of date or not comprehensive Some limited conservation initiatives are in place low
