The size of the breeding population of lynx is based on observations of family groups (females with kittens) reported to the management authorities. Observations include reports from the general public, farmers, herders, hunters, etc. and structured transect line surveys on snow. All observations are checked by local carnivore contacts from the State Nature Inspectorate and distance rules, based on known territory size and maximum daily displacement of radio marked individuals, are used to identify individual family groups. For families with multiple observations, we used the centre of their utilised area as the position of observation. Estimates of the abundance of the breeding population of wolverines are based on repeated visits to previously known dens, plus extensive searches for new dens. Dens are normally revisited 3–6 times to affirm reproductive status. We hereafter refer to these observations as lynx and wolverine population sizes. These estimates contain no estimates of measurement error. Reconstructions of population size of lynx and genetic capture-mark-recapture of wolverine however, reveal that the national monitoring program of lynx family groups and wolverine reproductions reflect population sizes well. All information regarding population size of large carnivores in Norway is obtained from the Norwegian Large Predator Monitoring Program at Rovdata

Here, we present density and number of reproducing lynx and wolverine registered within each reindeer herding region.
