Technical Approach • Evolution from VS to Repeat Inventory • High power for few, most common species • High natural variability • Informed by monitoring report and expert input Southeast Alaska Network Inventory and Monitoring Program
Logistics and Budget • $20K in FY12 to establish agreement • Design and implement first iteration • Sci.comm products • Periodic (10 years?) need for experts to assist with inventory Southeast Alaska Network Inventory and Monitoring Program
What we’re learning • Power to detect trend is high for barnacles, Fucus, and Littorinasnails. • Mobile and rare organisms under-represented • Random transects confound trend detection • Inventory will concentrate on presence/ND; algae, rare species Southeast Alaska Network Inventory and Monitoring Program
