Introduction
This report presents an analysis and summary of license year 2000 (LY00) Montana Special Big Game
hunter survey response information. Special Big Game includes Moose, Bighorn Sheep, and
Mountain Goats. Estimates of hunting and harvest statistics are presented for each Species by
Location hunted (Statewide, Regional, and by Hunting District), Residency of hunter (Residents, Non¬
residents, and Both combined), and Permit Type (Special Permit and All Permits combined).
Three Special Big Game hunting and harvest table types are presented for each of the 3
species:
1) Hunting Statistics Table: This table includes the number of special permits issued and the
expansion factor applied to the response data to obtain the estimates. Estimates are given for the
number of hunters and hunter days, lower and upper 80% confidence bounds on these
estimates, and relevant ratios based on these statistics.
2) Harvest Statistics Table: This table also gives the number of special permits issued and the
estimate of number of hunters. Estimates are also given for total harvest, lower and upper 80%
confidence bounds on harvest, harvest by sex-age class, percent harvest by sex-age class,
and relevant ratios based on these statistics.
3) Time Period of Kill Statistics Table: This table includes the estimate of total harvest and
the distribution of harvest among six time periods. Percent of total harvest within each time
period are also presented.
In addition, sampling effort and survey response information for each species is presented in:
• Sampling Statistics Tables: These tables include the number of permits issued, the number
of permit holders sampled, the number of holders responding to the survey, and rates and
ratios based on these numbers, including the expansion factor, for Moose, Bighorn Sheep, and
Mountain Goat.
These tables are organized based on the following four variables:
1) Species: All hunting and harvest statistics were computed separately for each of the three
species: Moose, Bighorn Sheep, and Mountain Goat.
2) Location of Hunt:
• Statewide (State): Statistics are computed without regard to the Special Big Game District hunted.
Provides an overall picture of hunting in Montana for the particular species.
• Regional (Reg 1...Reg 7): Statistics are computed based on MFWP Region of the District hunted.
• Hunting District: Statistics are computed based on the Special Big Game Hunting District in
which the permit is valid.
Special Big Game Hunting Districts differ for Moose, Sheep, and Goats (Montana Regulations -
Moose, Sheep, Goat, and Antelope Big Game Hunting 2000). Hunters report hunting effort and
harvest success for the special permit they hold. Each permit is valid in a single District.

3) Residency of Special Big Game Permit Holder:
• All: Statistics are computed without regard to residency of the permit holder.
• Residency (R/N): Statistics are computed based on residency status of permit holder as indicated
by the type of conservation license held. Montana resident is abbreviated R, non-resident N.
4) Special Permit Held by Sportsperson:
• All: Statistics are computed without regard to which Special Big Game Permit the sportsperson
held.
• License Type: All Special Big Game hunting is by special permit, and each survey response is
linked to a particular permit. Within a species, every special permit is identified by a unique 5 digit
code. These codes correspond to the permit code descriptions presented in the Regulations.
Overall Sampling and Survey Results
Table 1 presents overall statewide counts of number of permits issued, permit holders sampled and
surveyed by phone or mail, sportspersons who returned valid responses, and various rates derived
from these counts, expressed as percents, for each Special Big Game species, and by residency of
the sportsperson. Sample rate is the percent of permit holders surveyed for hunting and harvest
information. One hundred percent of Special Big Game holders are sampled. Return rate is the
percent of those sampled who returned valid survey information. Response rate is the bottom line
percent of permit holders who returned valid responses. Because the Sample Rate is 100 percent,
Return Rate equals Response Rate for Special Big Game.
Overall expansion factors (permit holders divided by valid responses) are also presented. Expanded
statistics were computed at all presented levels and combinations of Species, Location, Residency,
and License Type by multiplying the expansion factor by the corresponding non-expanded statistics.
Estimated Hunters is computed by multiplying the expansion factor by the number of responses
indicating active hunting. Hunting Rate is the estimated percent of permit holders actively hunting.
Estimated Harvest is computed by multiplying the expansion factor by the number of responses
indicating a kill. Percent Success is the estimated percent of active hunters successfully harvesting a
moose, sheep, or goat.

All estimated statistics and ratios are presented in the printed tables to a meaningful level of precision.
However, all calculations deriving these estimates and ratios were performed using high precision
floating point real numbers. Any subsequent calculations based on the formatted numbers presented in
the printed tables will be subject to round-off error.

In some cases, at the most detailed summary level by Species, Location, Residency, and Permit Type,
no response data were returned. In these cases, the expansion factor was undefined (permit
holders divided by zero responses). All estimates of hunting and harvest statistics based on an
undefined expansion factor are also undefined. In other cases, response data were returned, but no
sportspersons reported active hunting, or kills. This resulted in undefined ratios. All undefined
values were flagged as -9.9 in the underlying hunting and harvest data table. In the printed tables of
this report, undefined values are formatted to appear as -0 or -0.0.
Appendix A presents sampling statistics tables for all levels and combinations of Species, Location,
Residency, and License Type presented in the hunting and harvest statistics tables.

hunters. Percent of active hunters who are successful.
• Days To Kill: Hunter days divided by total harvest. An estimate of the average number of hunter
days required to harvest an animal.
• Tags To Kill: Permits issued divided by total harvest. An estimate of the average number of
permits which must be issued to harvest an animal.
Time Period of Kill Tables
The Special Big Game Time Period of Kill Tables present point estimates of Total Harvest, plus the
distribution of harvest by time period, for various levels and combinations of location hunted
(Location), license type held (Lie Type), and residency of hunter (Res). Percentages of harvest by
time period, based on these estimates, are also presented. Tables are presented for each Special Big
