Year of assessment Threat score (pressure) Condition score (state) Action score (response)
2018 high very unfavourable medium
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
Biological resource use fishing & harvesting aquatic resources - intentional use: subsistence/sml scale happening now majority/most of area/population (50-90%) slow but significant deterioration high
Climate change and severe weather habitat shifting and alteration likely in short term (within 4 years) some of area/population (10-49%) slow but significant deterioration medium
Human intrusions and disturbance work and other activities happening now small area/few individuals (<10%) slow but significant deterioration low
Invasive and other problematic species and genes invasive non-native/alien species/diseases - unspecified species past (and unlikely to return) and no longer limiting whole area/population (>90%) slow but significant deterioration low
