ITOC Audit
Recommendation
“Measure progress in meeting specific and detailed
EMP goals, objectives, and action items for regional
monitoring and management under the Management
Strategic Plan. Specifically, develop metrics using the
abundance of data to holistically understand the
status and trend of the overall health of the preserve
against the baselines established in regional
conservation plans and formalize a system to
communicate complex performance results to the
public.”

• System based
• Geographically based
• Indicators use existing
