ARCN Yellow-billed Loon Contaminants Monitoring
Arctic Network’s monitoring of the western Alaska YBLO population includes aerial surveys to determine populations occupancy and density, and assessment of contaminants burdens including but not limited to metals (e.g. mercury, Hg), persistent organic pollutants (POPs), organochlorine pesticides, perfluorinated hydrocarbons, polychlorinated biphenyl (PCB) congeners, polybrominated diphenyl ethers, and polycylic aromatic hydrocarbons (PAHs). Biennial aerial surveys specifically designed and optimized to detect YBLO (Stehn et al. 2005) have been conducted in western Alaska by USFWS and NPS since 2005 (Mallek et al. 2006, Bollinger et al. 2007, Flamme et al. 2011). In 2011, ARCN modified the lake-circling technique to assess sightability by using two Aviat Husky aircraft to conduct repeat aerial occupancy surveys of all selected YBLO plots in CAKR and BELA (Figure 1, Table 1). Herein, we propose to collect the first samples required to assess contaminants loads in the western Alaska YBLO population under the ARCN monitoring program.
