Mapping trends of large and medium size carnivores of conservation interest in Romania
<p>We analysed yearly estimates of population size data during 2001-2012 for five carnivores species of conservation interest (<em>Ursus arctos, Canis lupus, Lynx lynx, Felis silvestris and Canis aureus</em>). Population size estimations were done by the game management authorities...

| description | <p>We analysed yearly estimates of population size data during 2001-2012 for five carnivores species of conservation interest (<em>Ursus arctos, Canis lupus, Lynx lynx, Felis silvestris and Canis aureus</em>). Population size estimations were done by the game management authorities and integrated by the competent authorities on the Ministry of Environment and Climate Change. Trends in data were detected using non-parametric Mann-Kendall test. This test was chosen considering the short length of data series and its usefulness for non-normal distributed data. The trend was tested at three spatial scales: game management units (n=1565), biogeographical region (n=5) and national. Trends depicted for each game management unit were plotted using ArcGIS, resulting species trend distribution maps. For the studied period increasing population trends were observed for <em>Ursus arctos, Canis lupus, Canis aureus</em> and <em>Lynx lynx</em>, while for <em>Felis silvestris</em> there was no trend recorded. Such an analysis in especially useful for conservation proposes, game management and reporting obligations under article 17 of the EC Habitat Directive, using population trend as a proxy for population dynamics. We conclude that the status of the five carnivore species is favourable during the study period.</p> |
