IBA Monitoring

Most recent IBA monitoring assessment
Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2009 very high unfavourable medium
Was the whole site covered? Yes State assessed by Habitat
Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification annual & perennial non-timber crops - agro-industry farming happening now small area/few individuals (<10%) slow but significant deterioration low
Agricultural expansion and intensification annual & perennial non-timber crops - shifting agriculture happening now some of area/population (10-49%) slow but significant deterioration medium
Agricultural expansion and intensification annual & perennial non-timber crops - small-holder farming happening now small area/few individuals (<10%) moderate to rapid deterioration low
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - nomadic grazing happening now majority/most of area/population (50-90%) very rapid to severe deterioration very high
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - small-holder grazing, ranching or farming happening now some of area/population (10-49%) slow but significant deterioration medium
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 happening now whole area/population (>90%) slow but significant deterioration high
Human intrusions and disturbance recreational activities 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 some of area/population (10-49%) slow but significant deterioration medium
Natural system modifications dams & water management/use - abstraction of surface water (agricultural use) happening now small area/few individuals (<10%) no or imperceptible deterioration low
Natural system modifications fire & fire suppression - increase in fire frequency/intensity likely in short term (within 4 years) some of area/population (10-49%) slow but significant deterioration medium
Pollution agricultural & forestry effluents - herbicides and pesticides happening now small area/few individuals (<10%) no or imperceptible deterioration low
Pollution domestic & urban waste water - sewage happening now small area/few individuals (<10%) no or imperceptible deterioration low
Pollution garbage & solid waste happening now small area/few individuals (<10%) no or imperceptible deterioration low
Residential and commercial development housing and urban areas happening now small area/few individuals (<10%) slow but significant deterioration low

Condition of habitat (state)
Habitat Habitat Detail Reference Area (ha) Actual Area (ha) % of habitat remaining % of carrying capacity (overall) Result
Shrubland 0 0 moderate (70-90%) moderate (70-90%) unfavourable

Conservation actions taken at site (response)
Conservation Designation Management Planning Conservation Action Result
Whole area of site (>90%) covered by appropriate conservation designation No management plan exists but the management planning process has begun Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
