Capture and marking

Individual based data

To gather essential information about lynx ecology it is necessary to monitor individual animals.  We are able to monitor individual lynx from birth to death by using radio and GPS-transmitters. Thus, we can monitor lynx movements through different landscape types and estimate the effect on prey populations. The GPS-transmitter provides locations for marked lynx using satellites, until it drops off after 1-2 years. The locations are continuously sent to us using the cell phone network.  In areas without cell phone network we use transmitters that store the locations until they are downloaded manually. 



We use different capture methods.

  • Capture and marking of lynx in northern Scandinavia is carried out using helicopter.
  • In southern Sweden we mostly use dogs and walk-through box-traps.
  • In Southern Norway we mostly use walk-through box-traps and foot snares placed at lynx-killed roe deer. 

Use of animals for research

Capture and handling of wild animals can be controversial. There are strong regulations around the use of animals for research in Scandinavia to minimize the possible effects on the animals. All research and handling of wild animals are carried out by professional and experienced personnel.
