| DATA COLLECTION
AND ANALYSIS Game
harvest estimates are derived using a combination of information
from mailed questionnaires, successful hunter report cards, pelt
tagging records, a trapper report of catch, and field check reports.
The technique used to estimate harvest varies depending on the
species. Special
Permit Hunting Questionnaires
In addition to the
deer and elk general hunting seasons, there are special permit
hunts which make it possible to hunt antlerless deer or elk, special
areas, or during special times. Mountain goat, bighorn sheep,
and moose hunting are available only by special permit. All permit
hunters are sent a special permit hunting activity questionnaire.
All hunters, both successful and unsuccessful, are required to
complete and return this report at the close of the season. The
2000 permit hunter questionnaire return rates for spring
bear, deer, elk, mountain goat, bighorn sheep, moose, and fall
turkey were 95%, 76%, 80%, 95%, 100%, 99%, and 87% respectively.
Harvest for these species was tabulated and based solely upon
the reports returned by the hunters. Harvest was not estimated
to include hunters who did not return a completed report.
Hunter Questionnaire
A mailed questionnaire
is sent to a minimum of twelve percent of the people that purchase
hunting licenses in order to achieve responses from ten percent
of the hunters. Their answers on the questionnaire form the basis
upon which harvest estimates are made for deer, elk, black bear,
upland birds, waterfowl, and hunted fur-bearers. Hunters are asked
if they actually hunted, how many days they spent hunting, and
where it was done. They are also asked to record if they bagged
anything. If they did, they are asked what it was, where it was
taken, and how many they got. The deer and elk harvest tables
reflect only the "General" hunting season harvest. The special
deer and elk permit hunting seasons are tabulated separately and
are presented before the general season harvest.
A "three wave" mailer
is used to make sure that a true cross section is represented
in the sample of hunters. It is fairly common for hunters not
to respond if they were unsuccessful or did not get a chance to
hunt during the previous season. Consequently, those who respond
to the "wave one" questionnaire are proportionately the more successful
hunters. Subsequent mailings to those not returning the first
questionnaire encourage those hunters, who represent a more true
sample, to respond.
Harvest estimates are
made at different resolutions, depending on the sample size of
the species or user group. For example, modern firearm deer estimates
are made at the PMU (population management unit) level, which
is a group of game management units. Muzzleloader deer estimates
are made only at the regional level. This is because there are
significantly fewer muzzleloader hunters than there are modern
firearm hunters. More of the hunters in the smaller user groups
are sent questionnaires to compensate for the size of their group.
For deer and elk the harvest estimate is then divided proportionately
to the smaller geographic areas using returned harvest report
cards. The harvest tables can be misleading if the game management
units are closely compared. It is most useful to make comparisons
at the level the estimate is made, particularly when looking at
figures generated in previous years. The following table shows
sampling rates and at what resolution the actual harvest estimate
is made. Black
Bear Harvest
A "mandatory" report
card was introduced in the 1998 black bear and cougar season.
The report card was attached to each bear or cougar transport
tag and was to be completed and returned whether or not the hunter
was successful in bagging his/her animal. In addition, bear hunters
were given the option of reporting using a form on the WDFW internet
website or using a toll-free telephone number and reporting using
a telephone. |
