Fort Providence Moose Census, November/December 1997.
20 pp.
ABSTRACT
We conducted an aerial census of moose near
Fort Providence, N.W.T. We
estimated a population of 116 moose (density of 0.03-moose/sq. km) with a
90% confidence interval of 40 moose (35% of the population estimate).
The population has declined significantly (t=4.29, df = 46, p<
0.01) since 1994, when the population was estimated to be 255 moose, or
0.07-moose/sq. km. The calf:
100cow ratio was 16, also significant decline since 1994 when calf: 100cow
ratio was 31.5 (t= 2.25, p<0.05).
This census is the second in a row to document a significant
decline in the moose population of Fort Providence area; the 1991 census
yielded a population density of 0.17 moose/sq. km and a calf: 100cow ratio
of 55. Specific goals are
needed for population sizes of both bison and moose, and more research is
needed on the predator-prey relationships between moose, bison, wolves and
bears.
