IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2014 high very unfavourable negligible
Was the whole site covered? Yes State assessed by Habitat
Accuracy of information medium

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - agro-industry grazing, ranching or farmin happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Biological resource use hunting & collecting terrestrial animals - unintentional effects (species is not the target) happening now small area/few individuals (<10%) slow but significant deterioration low
Climate change and severe weather drought likely in short term (within 4 years) whole area/population (>90%) slow but significant deterioration high
Climate change and severe weather habitat shifting and alteration likely in long term (beyond 4 years) whole area/population (>90%) very rapid to severe deterioration high
Climate change and severe weather temperature extremes happening now whole area/population (>90%) slow but significant deterioration high
Energy production and mining mining and quarrying happening now small area/few individuals (<10%) slow but significant deterioration low
Energy production and mining renewable energy happening now some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance recreational activities happening now small area/few individuals (<10%) moderate to rapid deterioration low
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
Invasive and other problematic species and genes problematic native species/diseases - named species happening now majority/most of area/population (50-90%) slow but significant deterioration high
Pollution air-borne pollutants - type unknown/unrecorded happening now small area/few individuals (<10%) no or imperceptible deterioration low
Transportation and service corridors utility & service lines happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
