Accuracy of information good

Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Invasive and other problematic species and genes invasive non-native/alien species/diseases - unspecified species happening now some of area/population (10-49%) no or imperceptible deterioration low
Pollution agricultural & forestry effluents - nutrient loads happening now majority/most of area/population (50-90%) moderate to rapid deterioration high
Pollution domestic & urban waste water - type unknown/unrecorded past (and unlikely to return) and no longer limiting majority/most of area/population (50-90%) slow but significant deterioration low
Pollution excess energy - noise pollution happening now some of area/population (10-49%) no or imperceptible deterioration low
Residential and commercial development housing and urban areas happening now small area/few individuals (<10%) no or imperceptible deterioration low
