Year of assessment State Pressure Response
2022 not assessed very high very low
Whole site assessed? State assessed by Accuracy of information

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Biological resource use happe­ning now whole of popul­ation/area (>90%) moderate decline (10–30% over 3 gener­ations) very high
Transportation and service corridors happe­ning now most of popul­ation/area (50–90%) moderate decline (10–30% over 3 gener­ations) high

Response (conservation actions taken for the trigger species and/or their habitats)
