| 2009 Full Book | |
The national monitoring program for large carnivores monitors the Norwegian lynx population primarly through the survey of family groups (adult female lynx with dependent kittens). Each year the program estimates the minimum number of family groups that are present based on confirmed observations of family groups (tracks in snow, observations and dead kittens). The survey of tracks is mainly done by local people on snow, but all observed groups are reported to the State Nature Inspectorate (SNO) for confirmation. The minimum number of family groups estimated using a set of distance rules that are derived from radio-telemetry data on home range size and movement rates collected from lynx in Scandinavia. In this report we present results from Norway in the winter of 2008-2009, before the annual hunt began. Population development is based on annual results since 1996. On a national level there has been a 10-20% increase in the number of family groups reported since last year. In 2009 there were 80-91 family groups, which correspond to a total population size of 427-537 lynx. The management goal of 65 family groups set by the parliament in 2004 has been reached. To compare regional trends we have used the 8 management regions that the recent parliamentary white paper (St.meld.nir 15(2003-2004) "Rovvilt i norsk natur" Innst. S.nr.174) has created. In all regions, with the exceptions of region 2 (Aus t-agder, Telemark, Buskerud and Vestfold) and region 7 (Nordland), there are minor changes in the number of family groups. All seven regions with management goals have achieved this |
