Pressure (threats to the key species and/or their habitats)
Threat Timing Scope Severity Result
Transportation and service corridors happen­ing now some of popul­ation/area (10–49%) moderate deteri­oration (10–30% in 3 gener­ations) high
Human intrusions and disturbance happen­ing now some of popul­ation/area (10–49%) slow deteri­oration (1–10% over 3 gener­ations) medium
Energy production and mining likely in long term (beyond 4 years) some of popul­ation/area (10–49%) moderate deteri­oration (10–30% in 3 gener­ations) medium
Pollution likely in long term (beyond 4 years) few individ­uals/small area (<10%) rapid deteri­oration (>30% over 3 gener­ations) low
