Wolf
tracking operations have been underway in Värmland
since 1982, when the Swedish National Environmental
Protection Agency's trackers followed up reports of
wolf sightings from the northern part of the county.
At the end of the 1980's the Swedish
National Environmental Protection
Agency delegated responsibility for
wolf tracking to the Värmland
County Administrative Board. The
County Administrative Board reports
the
results of the tracking operations to the National Environmental Protection
Agency at the end of every season. The information in the report includes the
number of wolves tracked, the number of wolf territories and their geographical
location.
Tracking
methods:
In
order to gain an impression about the spreading of
wolves and their activities in Värmland and the
surrounding areas, it is necessary to regularly spend
time in the areas where the wolves are to be found.
Tracking operations begin in earnest when the ground
is completely covered in snow. Previously recorded
wolf territories are visited and a thorough counting
of individual paw-prints and following of tracks begins.
After a period of tracking, the number of wolves in
the area can be established.
The results are compiled and compared with previous years' tracking operations.
The number of new individuals is established, and the number of new cubs born
during the summer can thus be worked out.
The size of the territory and its appearance are also compared with results
from previous years. During the tracking operations, tracks and territory markings
made by the leader pair (urine and scratch markings) are registered on maps.
The compiled map image shows how the wolves move around in the terrain and
what the territory looks like.
All tracking operations are based on so-called "backtracking".
This means that a trail discovered in the terrain is followed in the direction
from which the animal or animals have come. In this way, there is very little
risk of encountering the wolf in question. In other words, trackers do not
wish to follow the animals in order to catch a glimpse of them, because this
causes the animals a great deal of stress.
By using the method of backtracking, the tracker can see what the animal
has done, where it has rested, how it has hunted and if it has succeeded
in catching any prey. In other words, much more information can be gained
from backtracking than from "forward tracking", where the animal
would quickly show escape behaviour or other unnatural movement patterns.
Wolves move around over large areas. Due to the fact that especially young
wolves move away from their home areas (where they were born and brought up),
it is important to investigate sightings and tips reported by the general public.
New wolf pairs can establish themselves in previously unoccupied areas, and
it is therefore important to be aware of the wolves' movements within the county,
and also in the surrounding border areas.

Your
observations and tips about wolves, lynx, wolverines
or bears are an important part of the work of mapping
the presence and spread of the animals in Värmland
and the surrounding area. We are grateful for reports
concerning sightings, tracks or other contact with
the above mentioned species.
