1. What
is the problem in the McGrath Area (Game Management
Unit 19D East)?
People in the communities of McGrath, Nikolai, Takotna, Medfra, and Telida are
not able to harvest the number of moose they need for food. Local people, who
depend on moose to feed their families, have asked the Governor, the Alaska Department
of Fish and Game, and the Board of Game for help.
The Department estimates that people in Unit 19D East need a harvest of about
140 moose per year for food. The Alaska Board of Game established a harvest objective
of 130-150 moose in Unit 19D East. At present, the moose population is supporting
a harvest of about 80-90 moose.
The problem is that people need to harvest more moose than can be provided by
the moose population in the McGrath area each year. Enough calves are born, but
most of them are being killed by bears and wolves during their first few months
of life.
2. Didn't recent surveys indicate more
moose in the McGrath area than originally thought, and doesn't this solve the
problem of low harvests?
A moose population survey conducted in November 2000, indicated very few moose
in the area. When compared with previous estimates in 1996 and 1999, it appeared
that moose numbers had dropped dramatically over the past decade, to one of the
lowest population densities ever documented. Reports and other documents written
before October, 2001, made reference to this apparent decline. A more intensive
survey conducted in October 2001 showed more moose in the area than the 2000
survey indicated. However, this density is still relatively low and it is unlikely
that the population will increase on its own or support a harvest of 130-150
moose. The problem of low moose harvest in this area still exists, and is likely
to persist indefinitely.
3. Is this problem the result of
people killing too many moose?
Yes and no. Even though the number of moose in the vicinity of McGrath is higher
than originally thought, it is still low enough that the harvest of bulls by
hunters is causing a low bull:cow ratio in that area. The replacement of new
bulls into the population is low because bears kill many calves, and wolves kill
many calves and adults.
4. How do bears and wolves affect moose numbers?
Black and grizzly bears kill many young moose calves (those that are 1-10 weeks
old). Grizzly bears also kill some adult moose during spring and summer. Wolves
kill calves and adults throughout the year. Together, bears and wolves kill most
of the calves that are born, and many yearlings and adults as well. This keeps
the moose population at a low level and prevents moose from increasing.
5. Is there a management plan for Unit
19D East, how was it developed and what is its status?
Department staff published a management plan for Unit 19D East in 2001 based
on recommendations from Governor Knowles' "Adaptive Wildlife Management Team" (AWMT).
The six members of the AWMT (from urban and rural backgrounds) met several times
over a period of about 12 months to discuss management strategies and options.
Their recommendations were submitted to ADF&G Commissioner Frank Rue for
consideration, and primarily focused on temporary reductions in wolf and bear
predation as well as temporary suspension of moose hunting. The Department's
plan included predator control, restrictions to hunting, and an intensive monitoring
program to scientifically document the effectiveness of the proposed intensive
management actions.
The plan was suspended before it went into effect when October 2001 moose surveys
indicated a higher density of moose than previously thought. At that point, it
was decided additional field studies and further analyses of data were needed
before intensive management actions were justified.
6. What is "adaptive wildlife management?"
There are several definitions of "adaptive wildlife management." As it is used
in this situation, it means a management action based on a formalized, closely
monitored process of trial and error. Models and assumptions are stated in advance.
As information is collected during the course of the management action, the models
and assumptions, and management actions are refined.
7. Did the Adaptive Wildlife Management
Team consider many ideas?
Yes, the team considered many different options to help rebuild the moose population.
The group evaluated several options in terms of feasibility, potential for success,
and cost. Examples of options that were not recommended included importing moose
from the Anchorage area (logistically impractical), using poison for predators
(not legal and not species-specific), and transporting local hunters to other
areas (too expensive and logistically impractical).
8. If we don't interfere, won't "nature
take its course?"
Yes, but that won't help the population of moose increase or provide more moose
for hunters.
Studies on predator/prey relationships and management experience in Alaska and
elsewhere during the last three decades have shown that wolf and bear predation
usually keeps moose populations at low levels even where hunting is minimal and
where there is enough food to support many more moose. Although moose numbers
may fluctuate slightly, the population cannot increase to a higher level until
substantially more calves survive to adulthood. The combination of wolf and bear
predation on low-density moose populations prevents them from increasing. If
predation is reduced, moose populations can increase and/or additional moose
can be harvested by people. However, if predator populations increase again to
high levels, moose numbers will likely decline again, resulting in lower harvests.
9. What will happen if nothing is done?
The population level and the number of bulls will remain low because relatively
few calves will survive to adulthood. If so, allowable harvest will have to be
kept at low levels indefinitely.
10. Would temporarily restricting the harvest
of moose solve the problem?
Restricting the harvest of moose would slowly cause the bull:cow ratio to increase,
but once normal harvest was resumed, the situation would likely repeat itself.
11. Some people have asked for predator control. Isn't this used
just to provide more moose for hunters to kill?
Yes, but hunting is an important way for Alaskans to provide food for their families.
This is especially true in rural areas like Unit 19D where there are no large
grocery stores, no roads and where shipping costs make food very expensive. Salmon
runs in this area have also declined in recent years.
12. Isn't predator control the reason wolves are a threatened species
in some of the continental 48 states?
The primary reason wolves no longer inhabit most of the contiguous 48 states
is because of many years of concerted efforts to eradicate them. Wolves were
eliminated from all of the contiguous United States except Minnesota because
they threatened livestock and because their prey animals (deer, elk, and bison)
were also reduced to very low levels by the 1880s. Today, however, wolves have
been reintroduced to Yellowstone National Park and Idaho, and are expanding rapidly
into Oregon, Washington, Wisconsin, and Michigan and nearby states.
The proposed Unit 19D East management experiment is not an eradication program
and is in no way comparable to programs that attempted (or succeeded) to permanently
eliminate wolves decades ago. Almost all of Alaska is suitable wolf habitat,
wolves are thriving, and the state has a commitment to maintaining wolf populations
in the future.
13. Couldn't you solve the problem by improving
habitat for moose?
In some situations improving habitat can help moose numbers increase. However,
research conducted in Unit 19D East indicates that habitat quantity and quality
are not limiting the moose population. Instead, the high level of wolf and bear
predation is preventing an increase in the numbers of moose or an increase in
the level of harvest. Improving and maintaining habitat
for moose is important for the future well-being of moose in Unit 19D East and
could play an important role in helping to sustain higher levels of harvest.
The Department is working with state and federal agencies and private land owners
to restore wild fire in the ecosystem so it can provide long-term benefits to
moose and other wildlife populations. The use of prescribed fire has begun, and
other habitat enhancement techniques are under consideration as well.
14. Why not let trappers take more wolves and hunters take more
bears?
The Board of Game liberalized hunting and trapping regulations for wolves, and
hunting regulations for bears in recent years in Unit 19D East. Harvests have
increased slightly and may increase further, but probably not much more. Liberalizing
current regulations can help increase harvests significantly in areas with roads
accessible by large numbers of hunters and trappers. But Unit 19D East is not
connected to a road system and has a relatively small number of hunters and trappers.
As a result, it is unlikely that liberalized regulations alone will be enough
to change the current situation of low moose numbers, high predation rates, and
low harvests by humans. If intensive management actions are used, higher wolf
and bear harvests will be necessary to maintain higher moose harvests in the
long run.
15. What is Fish and Game doing now?
At the present time moose hunting is controlled by registration permit to allow
the Department to closely monitor the harvest.
Currently the Department is conducting research to improve our understanding
of predation by bears and wolves on moose. The Department is also researching
seasonal moose movements, physical condition of moose, and habitat use and quality.
Data collected during 2001 and 2002 show that the moose population is relatively
stable and that wolves and bears kill nearly two-thirds of all moose calves born
each year. Local hunters are being encouraged to harvest more bears, particularly
black bears, in the vicinity of McGrath, Takotna, and Nikolai. The Department
conducted bear baiting clinics in this area. Local trappers are also being encouraged
to take more wolves. The harvest is being closely monitored.
16. How are decisions made about wildlife, and
how can I be involved?
The public influences decisions about wildlife management primarily through the
Board of Game and the Department. Regulatory proposals and public testimony (verbal
and written) can be presented to the Board for consideration at their regularly
scheduled meetings. The public can contact the Department to share concerns,
ask questions or make suggestions.
