Now that we know what a wildlife
manager is supposed to do, how do they get it done?
Like people in any job, wildlife managers have
tools.
MANAGEMENT PLANS describe the
tools a wildlife manager will use for keeping
wildlife within the carrying capacity of its
habitat. These plans must be flexible since the
wildlife populations, habitat factors and social
tolerances may change from year to year. It's also
important to note that the best wildlife management
plan often uses a combination of all, the management
tools available.
To develop a management plan,
wildlife managers must collect good information on
habitat and wildlife numbers throughout the year -
every year - to determine the type of tools needed.
HUNTING AND
TRAPPING
Today, hunting and trapping are
closely regulated so that some of the excess animals
in a population are removed each year. In fact,
hunting and trapping remain as one of the most
important management tools because hunters' can be
controlled by laws and regulations.
Hunting and trapping seasons are
longer and the harvests are greater during the years
of abundant game populations. Seasons may be
shortened and harvests smaller when game numbers are
down. In this way, hunting and trapping can be used
to keep wildlife populations healthy, to keep
wildlife within the carrying capacity of their
habitat and to protect the habitat from damage. They
are also used to reduce selected animal populations
to within social tolerances, even if the habitat and
carrying capacity are good.
RESEARCH AND
HARVEST SURVEYS
In order to properly manage any
wildlife species, biologists and managers must have
a good understanding of all the animals. Research
allows biologists and the rest of us to learn all we
can about animals and management. Research
objectives include:
Identify habitat needs for individual
species, and evaluate the impacts of a variety
of land use practices;
Study and explain the population dynamics
of wildlife under varying habitat and
environmental conditions;
Evaluate the social and economic values
of wildlife; and
Educate other biologists, wildlife
resource agencies, legislators and the public of
the results of the research and the needs of the
animals, habitat and the public.
Surveys are conducted annually as
a vital part of wildlife management programs. The
surveys are needed to evaluate:
How many animals were harvested from
certain populations or areas;
Trends in animal population levels,
habitat conditions or crop impacts;
Hunter pressure and over harvest patterns
on public and private land;
Basic biological information of the sex
and age of the animals harvested.
LAWS AND
REGULATIONS
If a species of animal is too few
in number, those animals can be protected by LAWS.
Hunting can be reduced or stopped to help lower
their death rate increasing population levels; as
with threatened or endangered species. In some
cases, laws may even be passed to protect the
habitat. Laws are mostly used when there is a need
for long-term or permanent actions.
If there are too many animals,
hunting can be used to reduce their numbers to the
proper level. Hunting REGULATIONS, for example, are
often changed from year to year to reflect changes
in animal numbers. Hunting season lengths may also
be adjusted to reflect the animal populations. Daily
bag limits or harvest quotas - the number of animals
that hunters can take in a day or season - can also
be set larger or smaller.
WILDLIFE
MANAGEMENT AREAS
WILDLIFE MANAGEMENT AREAS provide
another tool for wildlife managers. These are lands
which are set aside for the purpose of increasing
wildlife numbers by protecting wildlife and key
habitat.
One of the major goals of a
wildlife management area is to protect at least a
minimal number of animals so the population can
increase. But this type of protection can defeat its
own purpose. Deer and elk, for example, may increase
in numbers to the point where there are too many for
the available food supply. Damage to the habitat
then occurs. If a wildlife management area is to be
successful, the management plan must be flexible so
wildlife managers can keep animals, even animals in
a WMA, in balance with their habitat.
WATERFOWL REFUGES are perhaps the
most Successful of special wildlife management
areas. A waterfowl refuge may be a breeding area, a
wintering area or a migration refuge between
summering and wintering areas. Breeding area refuges
provide nesting habitat for producing young.
Wintering area refuges shelter the birds so they can
survive until the next breeding season. A migration
refuge provides a resting and feeding spot for birds
traveling to and from breeding or wintering areas.
Wildlife Management Areas are
effective only when correctly used in combination
with other management tools. Even though an area may
be managed for a specific animal, most wildlife
species benefit from the land and management
practices.
STOCKING can be used as a
management tool to start new wildlife populations or
to help areas that have small populations. The most
effective way is to trap wild animals from other
established populations and transplant them into new
areas because these animals already know how to
survive in the wild.
Stocking was begun more than 50
years ago in Montana. Among the wildlife species
that were introduced to Montana through stocking
were the ring-necked pheasant, Hungarian partridge
and Merriam's turkey. One of the problems of the
early stocking programs, however, was that wildlife
managers did not always consider the limitations of
habitat and social acceptance.
Today, wildlife managers
carefully study the areas before stocking, thus
increasing the chances of the animal's survival,
coexistence with existing species and people's
desire to have them there.
