  1. Kittlitz’s (and Marbled) Murrelets Glacier Bay National Park and Preserve Southeast Alaska Network Inventory and Monitoring Program

  3. Justification • Rare, pelagic seabird of AK, Russian Far East • Rangewide declines • 40-80% rangewide, at least since ~1990…earlier? • ESA Candidate, listing decision due in 2014 • GLBA is a major population center NPS Photo Southeast Alaska Network Inventory and Monitoring Program

  4. Justification • GLBA jurisdiction over uplands, marine waters, outer coast to 3 miles • Permitting authority for commercial, private party entries • Administrative and research traffic • If listed, what constitutes “take”? Southeast Alaska Network Inventory and Monitoring Program

  5. Objectives • To monitor annual abundance of KIMU in Glacier Bay proper in July, with 80% power (at a=0.05) to detect a decline of 25% over 15 years • To describe spatial variation in KIMU distribution in Glacier Bay proper Southeast Alaska Network Inventory and Monitoring Program

  6. Technical Approach • A spatially balanced, unequal sampling probability, serially augmented panel design • Spatial balance: GRTS • All the benefits of randomness while ensuring spatial balance • Unequal Sampling Probability • Similar to stratification • Informed, but not determined, by past densities • Panel design • emphasizes what we know, but allows us to capture distribution shifts Southeast Alaska Network Inventory and Monitoring Program

  7. Technical Approach • Tempered by constraints: 2 weeks, crew of 4, 1 vessel • No-go areas, planning around park regs • Early July, birds on the water • 10 kts transect speed NPS Photo: Moynahan Southeast Alaska Network Inventory and Monitoring Program

  8. Southeast Alaska Network Inventory and Monitoring Program May 6, 2009

  9. Logistics and Budget • Field work: 4 crew, 10 days early July • Analysis, reporting: 10 days each fall • Protocol development: $185K, FY08-11 • Annual Supplies: $2K SEAN, $2K GLBA (fuel) • Tech Assistance: $10K FY12 • Shared vessel: R/V Fog Lark • Periodic contracting for 5-y reports Southeast Alaska Network Inventory and Monitoring Program

  10. What we’re learning • Up-front investments in design are well worth it! • Field effort (km) down 79%, precision up 60% • Cheaper, more statistically sound, less exposure to risk, lower fuel consumption, reduced presence • Power to detect trend is much more sensitive (25% v. 50% over 15 y) Southeast Alaska Network Inventory and Monitoring Program

  11. What we’re learning • GLBA much more important than we thought… • Huge numbers of marbled murrelets • Annual variation in distribution • Upcoming opportunities to integrate distribution with oceanographic data Southeast Alaska Network Inventory and Monitoring Program

  12. Program Delivery Protocol Status: • All chapters, 10 of 12 SOPs drafted • Peer-review in May 2012 • National Audubon, July 2012 Southeast Alaska Network Inventory and Monitoring Program
