Marine Predators
Glacier Bay National Park and Preserve
Justification
• Emblematic and readily observable
• Management interest driven by conservation concerns or iconic status
• Apex predators as indicators of ecosystem health
• Renown productivity of Glacier BaySoutheast Alaska NetworkInventory and Monitoring Program
Justification
• GLBA jurisdiction over uplands, marine waters, outer coast to 3 miles
• Permitting authority for commercial, private party entries
• Administrative and research traffic
Southeast Alaska NetworkInventory and Monitoring Program
Objectives
• Determine long-term trends in the abundance and spatial distribution of marine birds and mammals within GLBA proper using grid-based sampling of at-sea surveys
• To describe spatial distribution of monitored species

Technical Approach… has evolved…
• Evaluated USGS all-species approach

Technical Approach… has evolved…
• Evaluated USGS all-species approach– Strong: distribution info, relative abundance– Weak: abundance estimation, trend detection for spp.
• Park: robust trends for a few key species• Polled an expert panel; ID candidate species
to capture range of niches• Most marine mammals covered elsewhere;
emphasis on seabirds

Technical Approach: BLKI• Long-lived colony
nester
• Year-round resident
• Questions about local, large-scale declines
• Legacy GLBA protocolSoutheast Alaska NetworkInventory and Monitoring Program

Logistics and Budget
• CESU Task Order (UAF, $28,000 FY11)– Review lit, legacy protocol– Analyze legacy, 2011 images– Recommendations
• Second Task Order ($64,000 FY12)– Design chapter, SOPs for data
processing, reporting

Working under the umbrella
• Finish KIMU, BLKI first• Move on to next
species… – Bald eagle– Barrow’s goldeneye– Glaucous-winged gull– Pigeon guillemot– Surf scoter– Sea otter

What we’re learning
• Sampling benefits compared to other species:– Colony nesters; loose aggregations; high visibility
• Large annual variation in counts: Breeding effort or photographic sampling?
• Productivity very difficult to monitor (chick, egg visibility)
• Approach: adults and nests at multiple colonies, annually
• Investigate identification of an index?Southeast Alaska NetworkInventory and Monitoring Program

Program Delivery• White paper in final
preparation, publish NRTR 2012
• New FY12 Task Order• 2012 Resource Brief• ~2,000 slides digitized,
catalogued, returned to GLBA
