the Area Biologist for
the Alaska Department of Fish &
Game. For a history of the Moose
Circle logo, click here.
ASSUMPTIONS:
2-year-old and younger cows do
not have calves.
3-year-old and older cows have
calves every year.
3-year-old cows always give
birth to a single calf.
4-year old cows always give
birth to twin calves.
Twin calves are born once every
three years, otherwise a single
calf is born.
Half the calves are bulls, half
are cows.
Only 14 years are depicted on
the cup, but cows will continue
to have calves for life (over 20
years).
RESULTS:
A cow will give birth to: 19
calves in 14 years.
Female offspring from one cow
will themselves give birth to an
additional: 184 calves in 14
years.
Total production from one cow,
and her female offspring is:203
calves over the 14 years;
(389 calves in 16 years; and 724
calves in 18 years and so on)
Half of all these moose are
bulls that we could harvest!
So when habitat isn't limiting,
not shooting cow moose will
allow a greater harvest.
The History behind the Moose
Circle
by AMF Chairman Gary Olson
I have had the pleasure of
meeting Roger Seavoy, Unit 18
Area Biologist who, in the
opinion of many including
myself, is truly dedicated to
his job of initiating and
maintaining healthy moose
populations throughout Western
Alaska. That definitely makes
him a friend and ally of The
Alaska Moose Federation.
Roger and I were discussing
current moose conditions during
the Summer of 2003 around the
Bethel area when he began
detailing an effort the
Department of Wildlife
Conservation is undertaking to
make area residents more aware
of the importance of cow moose
and that their removal from a
herd is counter productive to
its increasing potential. This
design, as far as Roger knows,
was first developed by Bob
Stephenson, the Ft. Yukon Area
Biologist who passed it on to
Randy Kaycon, the previous
Bethel Area Biologist. Roger has
placed the design onto coffee
mugs handed out to hunters to
provide visual proof of the
importance of cow moose.
The Alaska Moose Federation
proudly displays the moose
circle and tells its story
throughout Western Alaska. This
design is living proof of the
decades of effort that past
biologists have put into our
Alaskan moose. This organization
is dedicated to bring all of our
moose knowledge into one forum
to make sure today’s moose
management is getting the best
information possible. |
