Medium - based upon reliable but incomplete / partially representative data

Energy production and mining mining and quarrying happening now small area/few individuals (<10%) very rapid to severe deterioration low
Invasive and other problematic species and genes invasive non-native/alien species/diseases - named species happening now some of area/population (10-49%) slow but significant deterioration medium
Over-exploitation, persecution and control of species gathering terrestrial plants - unintentional effects (species being assessed is not the target) happening now majority/most of area/population (50-90%) no or imperceptible deterioration low
Over-exploitation, persecution and control of species hunting & collecting terrestrial animals - intentional use (species being assessed is the target) past (and unlikely to return) and no longer limiting whole area/population (>90%) no or imperceptible deterioration low
Over-exploitation, persecution and control of species logging & wood harvesting - unintentional effects: subsistence/small scale past (and unlikely to return) and no longer limiting some of area/population (10-49%) moderate to rapid deterioration low
Pollution domestic & urban waste water - type unknown/unrecorded happening now small area/few individuals (<10%) slow but significant deterioration low
Pollution industrial & military effluents - type unknown/unrecorded happening now some of area/population (10-49%) slow but significant deterioration medium
Residential and commercial development housing and urban areas past (and unlikely to return) and no longer limiting 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%) slow but significant deterioration low
