Abstract

Eurasian lynx (Lynx lynx) have a wide distribution across Eurasia. The northern edge of this distribution is in Norway, where they reach up to 72 degrees north. We conducted a study of lynx space use in this region from 2007 to 2013 using GPS telemetry. The home range sizes averaged 2606 (± 438 SE) km2 for males (n=9 ranges) and 1456 (± 179 SE) km2 for females (n=24 ranges). These are the largest home ranges reported for any large felid, and indeed are only matched by polar bears, arctic living wolves, and grizzly bears among all the Carnivora. The habitat occupied was almost entirely treeless alpine tundra, with home ranges only containing from 20 to 25 % of forest. These data have clear implications for the spatial planning of lynx management in the far north as the current management zones are located in unsuitable habitats and are not large enough to encompass individual lynx movements.

Methods

Home ranges are based on locations from GPS-collars fitted on Lynx. The different types of home range estimators are given in the file.

Usage Notes

There are two csv files, 1 containing home range sizes for all lynx with different range estimators and 1 containing overlap in home ranges between and within individuadls based on the MCP 100% home range estimator
