Energy production and mining renewable energy likely in short term (within 4 years) small area/few individuals (<10%) moderate to rapid deterioration low
Human intrusions and disturbance recreational activities likely in short term (within 4 years) some of area/population (10-49%) moderate to rapid deterioration medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation Management planning Other conservation action Result
Whole area of site (>90%) covered by appropriate conservation designation A management plan exists but it is out of date or not comprehensive Some limited conservation initiatives are in place medium
