Summary of aerial survey observations from 1988 to 2005 that collected abundance, trend, and distribution of waterbird nesting populations in the Yukon-Kuskokwim Delta. Surveys were conducted from the mouth of the Yukon River in the north to Kuskokwim Bay in the south and extended 50 km inland.
... The objectives of the bird field surveys were to document the current composition, distribution and abundance of bird populations (primarily waterbirds), and the location of important habitat and staging areas (e.g., nesting colonies, major waterfowl moulting areas and migratory staging sites) in the production area. The Mackenzie Gas Project production area encompasses the three anchor fields (Taglu, Niglintgak and Parsons Lake) and the gathering pipeline system. ... The results of these surveys were used to assess potential project impacts and develop mitigation plans associated with the proposed pipeline project. ... Bird surveys in the production area were conducted during spring migration (late May to early June 2002), summer nesting (early June to mid-July 2002) and fall staging and migration (late July to mid-September in 2001). The survey effort, i.e., distance flown, focused primarily on aerial surveys for waterbirds (loons, grebes, geese, swans and ducks) and other large, conspicuous birds (hawks, eagles, falcons, jaegers, gulls, terns, owls, sandhill cranes and common ravens). Ground-based surveys were also used to ground-truth the results of aerial surveys and to provide data on nesting shorebirds and passerines. Ground-based surveys were limited in scope. Additional surveys are proposed as part of site-specific permit applications. Bird surveys were conducted on the outer Mackenzie Delta, in the Parsons Lake area, and along the proposed gathering pipeline corridor. Surveys of the outer Mackenzie Delta included coverage of the Taglu and Niglintgak leases and areas between and around those leases. Similarly, surveys of the Parsons Lake area included the lease and surrounding areas. Four types of surveys were used to document bird populations within the production area ...: spring aerial surveys, aerial transect surveys, ground-truthing surveys, breeding-bird plot surveys. The areas covered in the field sampling program were delineated, based on a project footprint that was under preliminary design at the time. Although some areas now deviate from the preferred route of the pipeline and the more recent placement of the facilities, the habitat types and areas inhabited by birds are still relevant for the impact assessment presented in the filed Environmental Impact Statement (EIS)--Overview.
... The objectives of the field surveys were to document the current composition, distribution and abundance of bird populations (primarily waterbirds), and the locations of important bird habitat and staging areas, e.g., nesting colonies and staging sites, along the Mackenzie Valley pipeline corridor. The pipeline corridor extends south from the Inuvik area facility in the Gwich'in Settlement Area, Northwest Territories, to near Bootis Hill, Alberta. ... The results of these surveys were used to assess potential project impacts and develop mitigation plans associated with the proposed pipeline project. ... Bird surveys were conducted along the pipeline corridor during spring migration (mid-May to early June 2002) and the summer nesting period (mid to late June 2001). Survey effort focused primarily on aerial surveys for waterbirds, i.e., loons, grebes, geese, swans and ducks, and other large, conspicuous birds, i.e., hawks, eagles, falcons, jaegers, gulls, terns, owls, sandhill cranes and common ravens. Ground-based surveys were also used to ground-truth the results of the aerial surveys, and provide data on nesting passerines. Additional surveys are proposed as part of site-specific permitting applications. Bird surveys were conducted along the proposed pipeline corridor, along the Mackenzie River and in several areas near the pipeline corridor. South of Norman Wells, surveys of the proposed pipeline corridor followed the existing Enbridge Pipeline right-of-way. Four types of surveys were used to document bird populations along the pipeline corridor ...: spring aerial surveys, aerial transect surveys, ground-truthing surveys, point count surveys. The areas covered in the field-sampling program were delineated based on a project footprint that was then under preliminary design. Although some areas now deviate from the preferred route of the pipeline and the more recent placement of facilities, the habitat types and areas inhabited by birds are still relevant for the impact assessment presented in the filed EIS--Overview.
