Year of assessment State Pressure Response
2007 not assessed medium medium
Whole site assessed? State assessed by Accuracy of information
yes unset good

Pressure (threats to the trigger species and/or their habitats)
Threat Timing Scope Severity Result
Human intrusions and disturbance happening now some of area/population (10-49%) slow but significant deterioration medium
Natural system modifications likely in short term (within 4 years) small area/few individuals (<10%) slow but significant deterioration low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas Management plan Other 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90%) covered by appropriate conservation designation A management plan exists but it is out of date or not comprehensive Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity medium
