Title: 2017 Results for Avian Monitoring at the TA-36 Minie Site, TA-39 Point 6, and TA-16 Burn Ground at Los Alamos National Laboratory

Abstract

Los Alamos National Security, LLC (LANS) biologists in the Environmental Compliance and Protection Division at Los Alamos National Laboratory (LANL) initiated a multi-year program in 2013 to monitor avifauna (birds) at two open detonation sites and one open burn site on LANL property. Monitoring results from these efforts were compared among years to monitor trends. The objectives of this study were to determine whether LANL operations impact bird species richness, diversity, abundance, or composition. Additionally, nesting success of secondary-cavity nesting birds was examined using nestboxes. LANS biologists completed the fifth year of this effort in 2017. The overall results from 2017 continue to indicate that operations are not negatively affecting bird populations; however, we are seeing some species turnover through time and that will continue to be monitored. Three bird point count surveys were completed at each of the treatment sites at the Technical Area (TA) 36 Minie site, the TA-39 point 6, and the TA-16 burn ground between May and July 2017. A total of 785 birds representing 59 species were recorded at the treatment sites. Three bird point count surveys were also completed at each of the control sites between May and July 2017. Occupancy and nest successmore » data from nestboxes at treatment sites were compared with the overall avian nestbox monitoring network. Species richness and diversity at the treatment sites were not statistically different than their associated controls. Avian abundance showed more variability but treatment and controls were trending together year to year. Species composition seems to indicate some species turnover in the habitat types but very little difference between treatment and control sites.« less
