Sammendrag
The Scandinavian wolf population is jointly monitored by Norwegian and

Swedish authorities. Monitoring is made annually. Wolves are classified in

different categories. Family groups ( 3 animals sharing a territory), territorial

pairs, other stationary wolves, and vagrants. Also number of reproductions

are determined each year, and has the highest priority as national

management goals for the wolf population in both countries are expressed

as number of reproducing units. Three methods are used in combination.

Tracking on snow is the basic method. Around 100 field workers are employed

full time or part time to find and follow tracks of wolves during the

monitoring season Oct. 1 – Feb 28. The second method is DNA-analysis,

mainly based on wolf scats collected during tracking. DNA-analysis help

verifying reproductions, identifying newly established pairs, differentiating

between neighboring territories and for identifying new immigrants from

the Finnish/Russian population. The third method is radio telemetry. 10-20

wolves are equipped with GPS-collars each year, and used for determining

of territory extents and differentiating between neighboring territories. All

monitoring data are recorded in national databases, and compiled each year

in an annual monitoring reports. Annual budget for large carnivore monitoring

in the two countries combined in 2011 was approximately 5.8 million

Euro, of which approximately 1.5 million was spent on wolves.
