Survey & Inventory


ABR’s team of scientists has extensive experience in quantifying the distribution and abundance of wildlife in terrestrial, marine, and aerial environments. Our scientists have worked safely in arctic to tropical conditions covering a broad suite of studies from baseline surveys for terrestrial and aquatic wildlife to focused monitoring of threatened and endangered species and occupancy modeling of sensitive species. Our specific areas of expertise include:

  • design and analysis of complex field studies
  • cutting-edge sampling  methods for wildlife monitoring (e.g., thermal imaging and motion-sensitive cameras, satellite telemetry, UAVs, ornithological radar, night-vision equipment, bat detectors, helicopter and fixed-wing aerial surveys, boat-based surveys)
  • line-transect sampling and analytical methodologies
  • avian point-count surveys for baseline conditions, population monitoring, and restoration efforts
  • long-term population-monitoring surveys (e.g., Peregrine Falcon, Marbled Murrelet, Northern Spotted Owl, Brant, Tundra Swans, Yellow-billed Loons, Snow Geese)
  • Bald and Golden eagle surveys for wind-energy projects
  • raptor nesting and productivity surveys
  • aerial surveys for caribou, moose, bears, fox dens, seals, sea otters, seabirds, passerines, shorebirds, and waterfowl
  • site-characterization surveys for wildlife and sensitive habitats at wind and solar projects
  • nocturnal radar and visual surveys for birds
  • bat acoustic-monitoring surveys
  • amphibian surveys
