2. Justification Intertidal areas are diverse, biologically sensitive habitats vulnerable to disturbance. Fuel spills and boat groundings are constant threats. Trampling from high visitor use affects some areas (SITK). Southeast Alaska Network Inventory and Monitoring Program

3. Objective Determine the changes over time of species composition and distribution Identify those caused by anthropogenic activity Southeast Alaska Network Inventory and Monitoring Program

4. Southeast Alaska Network Inventory and Monitoring Program May 6, 2009 Sitka Intertidal

5. 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

6. 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

7. 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 species Southeast Alaska Network Inventory and Monitoring Program
