| Monitoring in Lynx (_Lynx lynx_) in North Rhine-Westphalia - records from the years 1985 to 2011 (Luchsmonitoring (_Lynx lynx_) in Nordrhein-Westfalen- Hinweise aus den Jahren 1985 bis 2011) | |
| 2012 S„ugetierkundliche Informationen (45): 463-481 | |
Since 2005 records on the occurrence of lynx are documented by volunteer lynx obsesrvers according to the uniform standards in Germany and evaluated, analysed and archived in the 'Forschungsstelle fr Jagdkunde und Waldschadensverhtung, Landesbetrieb Wald und Holz NRW' (Research institute for hunting and prevention of wood damage). In Germany the Federal Agency for Nature Conservation (BfN) coordinates the adjustments of methods, compilation of data and the necessary evaluation of the conservation status for the lynx on the national level. The size of the distribution area, the population size, the size of the habitat and the future prospects have to be evaluated, including adverse effects, endangerment and long term survival potential. In North-Rhine Westphalia the regional authority for Nature, Environment and consumer protection coordinates all activities that are required by Article 11 of the Habitat directive. The implementation for the lynx is carried out by the 'Forschungsstelle fr Jagdkunde und Waldschadensverhtung'. With the first record of a wolf in NRW in November 2009 it has been suggested to use the network of lynx observers also in the monitoring of the wolf. The last lynx in Westphalia was killed in 1745. In 1985 a lynx was recorded in the district Euskirchen. Several observations of lynxes in the German / Belgian border region followed in 1997/98 and 2003. In Westphalia lynxes have been observed in 1999 in the Arnsberger wood, since 2008 in the Teutoburger wood and in the summer of 2011 a female lynx with two kittens was recorded in the district Olpe, east of the Rhine. Among the 346 records from the years 1985 to 2011 there were 29 unambiguous 'hard fact' data (C1), 9 confirmed records (C2) and 243 unconŸOrmed records (C3). The suitability of the habitats, number and origin of the assured lynxes and indications of reproduction and mortality are discussed. North Rhine-Westphalia possesses about 9 000 km2 woodlands, mainly in low mountain ranges; potential habitat for lynx. Lepus europaeus, Capreolus capreolus, and Sus scropha are suitable prey species which occur in all low mountain ranges. Cervus elaphus occurs in wide areas, locally also Dama dama, Cervus nippon and Ovis musimon. |
