ABSTRACT
Post-calving
aggregations of the Kaminuriak herd were located by radio-tracking 34
females and 4 males. The
groups located were recorded by oblique photography on 35mm slides, if
they were in tight enough formation to facilitate this method.
This was done over two sampling periods -- July 13 - 14 and July
18 - 19, 1987.
The
caribou images on the resulting photos were later counted and, using the
ratio of radio collars in the groups photographed to the total radio
collars in the population, an extrapolation was used to estimate the
total size of the population. The
two samples yielded two estimates: one of 230,000; the other, 260,000.
Evidence of males missing from the samples suggests that these
estimates may be low.
