(1) the objectives for the program are as
follows:
(A) to increase the Unit 20(D) fall
moose population to 8,000 - 10,000 moose with a sustainable harvest of 500 -
700 moose per year;
(B) to reverse
the decline of the Macomb caribou herd and increase the fall population to 600
- 800 caribou with a sustainable harvest of 30 - 50 caribou per year;
(2) if the commissioner or the
commissioner's designee conducts a wolf population reduction or a wolf
population regulation program, the program must be conducted in the following
manner to achieve the objectives in (1) of this subsection:
(A) for up to five years beginning July 1,
2004, the commissioner may reduce the wolf population in Unit 20(D); however,
the commissioner may not reduce the wolf population within the Unit 20(D) wolf
predation control area to fewer than 25 percent of the early-winter wolf
population before initiation of the program; and
(B) the commissioner shall reduce the wolf
population in an efficient manner, but as safely and humanely as
practical;
(3) hunting
and trapping of wolves by the public in Unit 20(D) during the term of the
program may occur as provided in the hunting and trapping regulations set out
elsewhere in this title, including the use of motorized vehicles as provided in
5
AAC 92.080; however, if the wolf population is reduced
to 25 percent of the early-winter, pre-control size, the commissioner shall
stop all taking of wolves until the wolf population increases;
(4) annually, the department shall, to the
extent practicable, provide to the board, at the board's spring board meeting,
a report of program activities conducted during the preceding 12 months,
including implementation activities, the status of prey and predator
populations, and recommendations for changes, if necessary, to achieve the
plan's objectives;
(5)
justification for the program, and wildlife population and human use
information, is as follows:
(A) consumptive
use of moose and caribou has been a priority human use of wildlife in Unit
20(D) for decades; human demand for harvest of these species remains high in
Unit 20(D); the board determined the moose population in Unit 20(D) and the
Macomb caribou herd are important for providing high levels of human
consumptive use; the board established objectives for population size and
annual sustained harvest of moose in Unit 20(D) and the Macomb caribou herd
consistent with multiple use and principles of sound conservation and
management of habitat and all wildlife species in the area; these objectives
are to have a moose population of 8,000 - 10,000 with an annual sustainable
harvest of 500 - 700 moose and to have 600 - 800 caribou in the Macomb herd
with an annual sustainable harvest of 30 - 50 caribou;
(B) the Unit 20(D) moose population was
estimated to be 6,002 - 7,770 moose in fall 2003 based on Geostatistical
Population Estimation; the annual harvest from Unit 20(D) has averaged about
204 moose per year for the past five years; both the population size and
harvest are well below the management objective levels;
(C) the moose population in Unit 20(D) is
divided into three subpopulations for management purposes: northern Unit 20(D),
southeastern Unit 20(D), and southwestern Unit 20(D);
(D) the northern Unit 20(D) moose population
is estimated to be 2,070 - 2,719 moose; moose calf survival to fall was 18
calves to 100 cows in 1999; moose habitat quality is moderate in northern Unit
20(D), with extensive areas of subalpine habitat, lowland habitat associated
with several major rivers and creeks, and numerous areas burned by wildfire
within the last 1 - 30 years; the resident and nonresident hunting season is
September 1 - 15 for any bull; during the last five years, an average of 261
hunters per year killed an average of 67 moose per year;
(E) the southwestern Unit 20(D) moose
population is estimated to be 2,655 - 4,689 moose; moose calf survival to fall
was 32 calves to 100 cows in 2003; moose habitat quality is good with extensive
areas of subalpine habitat, several major wildfires in the 5 - 15 years, and
large areas of cleared land that are revegetating with moose browse; the
resident hunting season is September 1 - 15 for one bull with spike-fork or
50-inch antlers or antlers with four or more brow tines on at least one side;
the nonresident season is September 5 - 15 for one bull with 50-inch antlers or
antlers with four or more brow tines on at least one side; the Delta Junction
Management Area and the Bison Range Youth Hunt Management Area is hunting by
drawing permit within this portion of Unit 20(D); during the last five years,
an average of 432 hunters per year killed an average of 118 moose per
year;
(F) the southeastern Unit
20(D) moose population is estimated to be 544 - 1,162 moose; moose calf
survival to fall was 24 calves to 100 cows in 2003; moose habitat quality is
good with extensive areas of subalpine habitat and lowland habitat along the
Tanana River; the resident hunting season is September 1 - 15 for any bull;
there is no open season for nonresidents, except within a portion of the
Robertson River drainage; the Macomb Plateau Controlled Use Area within this
portion of Unit 20(D) restricts motorized access for hunting, and makes moose
hunting difficult in much of this area; during the last five years, an average
of 47 hunters per year killed an average of 13 moose per year during the
general hunting season;
(G) the
Unit 20(D) grizzly bear population can be estimated by extrapolation from bear
research data collected in adjacent units; the extrapolated estimate for Unit
20(D) is 181 - 210 total grizzly bears, with 143 - 176 bears older than two
years; the grizzly bear estimate for southeastern and southwestern Unit 20(D)
combined is 76 - 86 total bears, including 51 - 58 bears older than two years;
in northern Unit 20(D), the grizzly bear population is estimated to contain 105
- 124 total bears with 92 - 109 bears older than two years; human-caused
grizzly bear mortality has averaged 14 bears per year for the last five
years;
(H) black bears occur
throughout Unit 20(D) at low to mid elevation; no estimate of black bear
density or population size can be made; both black bears and grizzly bears are
known to prey on moose in Unit 20(D), but the extent of predation has not been
measured; human-caused black bear mortality has averaged 22 bears per year for
the last five years;
(I) the Macomb
caribou herd declined significantly in size from 800 caribou in fall 1990 to
458 in fall 1993; the herd increased to 550 - 575 by fall 2003 with a ratio of
19 calves to 100 cows;
(J) winter
weather in Unit 20(D) has been moderate for the past five to eight
years;
(K) extensive research in
Alaska and northern Canada demonstrates the potential for naturally regulated
wolf and bear populations to regulate moose numbers at densities well below the
forage-carrying capacity of the habitat; potential harvest from such moose
populations is low; it is likely that the moose population in Unit 20(D) fits
this pattern, particularly in northern Unit 20(D); unless combined wolf and
bear predation is reduced, the moose population will not increase to objective
levels in spite of mild weather, abundant high quality forage, and restrictive
hunter harvest;
(L) bear
regulations have been liberalized in portions of Unit 20(D) for several years;
in parts of the unit, grizzly numbers are probably reduced somewhat as a result
of hunter harvest and other human-caused mortality; no corresponding increase
in moose or caribou numbers or harvestable surplus is evident as a
result;
(M) the fall 2002 wolf
population is estimated to be 88 - 98 based on aerial surveys, incidental
observations, sealing records, and interviews with knowledgeable trappers; an
average of 38 (41 percent of the population) wolves per year have been taken by
hunting and trapping during the past five years; this is below the harvest
necessary to result in a population reduction; in addition several packs in
northern Unit 20(D) were treated during the Fortymile Nonlethal Predation
Control Program and still contain sterilized pairs of wolves;
(N) if local hunters and trappers do not
achieve adequate wolf reductions, the commissioner may issue public aerial
shooting permits or public land and shoot permits as a method of wolf removal
under AS
16.05.783; if this is unsuccessful in
achieving adequate reduction of wolf numbers, the commissioner may implement
aerial shooting by the department.
