In contrast, six years (1990-95) of extensive aerial surveys in and around the PBOF during the post-calving period indicated frequent use of, and movements through, the PBOF (Pollard et al., 1996a).
Because of continued concerns over potential disturbance and displacement of caribou from the PBOF (Cameron, 1995; Cameron et al., 1995; Nellemann and Cameron, 1996), we assessed caribou distribution using the survey data collected between 1990 and 1995.
The PBOF survey area lies between 147[degrees]41' and 149[degrees]00' west longitude and extends south from the Beaufort Sea coast to 70[degrees]05' north latitude (Fig.
Between 1990 and 1995, we conducted 37 surveys of the PBOF during the post-calving period.
In summary, the log-linear analyses, without combining data into intervals, indicate that caribou distribution in the PBOF is unrelated to the covariates (distance from infrastructure, distance from the coast, Julian data, year).
Our results indicate that during the post-calving period, caribou are abundant in the PBOF; they often occur close to oil field infrastructure; and their overall distribution is largely unrelated to the distribution of infrastructure.
observations recorded during 37 aerial surveys of the entire PBOF. Surveys were distributed between 20 June and 18 August for each of six consecutive years.
