Alaska Yukon Delta Nest Distance Sampling Pilot Project In 2019 a pilot study was conducted to determine the feasibility of using distance sampling to estimate density and population size of goose and eider nests on the Yukon-Kuskokwim Delta (YKD). Distance sampling (Buckland et al. 2001) is a common and well-understood method to estimate wildlife population size or density, especially for sparse and hard-to-detect populations. A main advantage of distance sampling is that it accounts for imperfect detection and gives precise estimates for a given level of effort relative to other methods. The objectives for the pilot project in 2019 was to (1) determine if distance sampling is feasible on the YKD, (2) determine what aspects of the field protocol need to be changed or...

Joint Base Elmendorf-Richardson (JBER) located in Anchorage, Alaska, provides critical nesting habitat for five avian Species of Special Concern (SOSC): Solitary Sandpiper Tringa solitaria, Lesser Yellowlegs Tringa flavipes, Olive-sided Flycatcher Contopus cooperi, Rusty Blackbird Euphagus carolinus and Blackpoll Warbler Setophaga striata. Joint Base Elmendorf-Richardson derived the Species of Special Concern list from the Birds of Conservation Concern (USFWS 2008) and the Department of Defense Mission-Sensitive Priority Bird Species (DoD PIF 2015) lists. Department of Defense Partners in Flight recognizes...
