Some Estimates of Moose Populations in British Columbia During ...

The second period covers the years 1961 to 1966,
using Method 2 for calculation, and provides a mean of
135,000 for the fall population. The male:female:
juvenile ratio applied in the calculation was 1.0
2.2 : 0.9. This was derived from the 1955 - 1957
cache creek Records, the closest data available, and
possibly favours the female component too highly if
the trend noted above continued into the second
period.
The male component is minimal, based on the
numbers which must have been alive in each year in
order to subscribe to later harvests.
Also during the second period of 1961 -
1966 the
spring populations, calculated by Method 3, show a mean
for the period of 100,930 consisting of 39,870 males
and 61,057 females.
The population estimates by this
method of calculation range from 84,075 in the year
1962 to 111,169 in the year 1966. There is thus a
high degree of consistency in the data, collected
independently in each of the years 1961 to 1970, which
forms the basis of the estimates.
The estimates for
the female component show more variation than those
for the male component, which is not surprising as
they depend on fewer observations because of smaller
numbers of females in the harvest.
