• Fuel spills and boat groundings are constant threats. Trampling from high visitor use affects some areas (SITK).

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

What we’re learning
• Power to detect trend is high for barnacles, Fucus, and Littorina snails.
• Mobile and rare organisms under-represented
• Random transects confound trend detection
• Inventory will concentrate on presence/ND; algae, rare speciesSoutheast Alaska Network
