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).

Objective

• Determine the changes over time of species composition and distribution

• Identify those caused by anthropogenic activity

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

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
