| Today,
the wolf has established a small but permanent population
in Scandinavia. In February 1998 there were around
ten known pairs, and a number of lone wolves. In total,
the wolf population of Norway and Sweden is estimated
to consist of 50 individuals.
The
story of the return of the wolf is extremely interesting
and exciting. How can a species which was believed
to be extinct in this part of the country return? And
why did it return to the counties of Värmland
and Dalarna?
Perhaps
it isn't so strange that the wolf has become established
in this area. The sparsely populated Värmland
forest landscape along with an extremely rich elk population
provide the shy wolf with exactly what it requires;
plenty of living space, an undisturbed environment
and a good supply of food.
Two
factors which could counteract the growth of the wolf
population are road accidents and illegal hunting.
It is difficult to estimate the hidden statistics in
these cases. Are these factors really important for
the development of the wolf population, or are they
irrelevant?
One
positive factor for the growth of the wolf population
is the predator fences which the Värmland County
Administrative Board began to place around herds of
domestic cattle in areas central to the wolf population
in 1992. About 80 fences have been put in place with
good results. No domestic animals have been attacked
inside fences which have been in operation. There have,
in fact, been very few cases of wolves attacking domestic
cattle in recent years.
Stable
population:
Towards
the end of 1997, the Swedish National Environmental
Protection Agency's proposed program of measures for
wolves was sent out for consideration. The proposal
suggests that the Scandinavian wolf population should
consist of "fifteen pairs, or perhaps one hundred
individuals".
Predator researchers at the Center for Biological Diversity have, in their
comment to the proposal, stated that a population of at least two hundred animals
is necessary if it is not genetically isolated. If the population was genetically
isolated, a population of at least five hundred animals would be necessary
to ensure that the wolf would survive in the long term under natural circumstances
in this country.
Today the Scandinavian wolf population consists of about 50 - 70 animals, but
due to the fact that there are now several pairs, the long-term objective may
perhaps be achieved in a few years time. It may, however, take longer, because
reproduction is dependent upon a stable number of reproductive alpha pairs.
Alpha animals which are shot or run over by cars will cause a delay in the
population increase, because wolf families are then split up. Another consequence
of split families is an increase in the number of lone wolves seeking to establish
their own territory.
Hunting:
Once a decision has been made about the size of the wolf population, the question
of hunting wolves in Sweden will arise. To begin with, this may take the form
of the protective hunting of individual animals, but may later develop into
more comprehensive hunting in order to keep the population at the level stated
in the long-term objective, i.e. fifteen pairs or one hundred individuals.
It is, however, obvious that many problems may arise concerning the practicalities
of wolf hunting.
