摘要: Abstract Estimating population size and trends are key issues in the conservation management of large carnivores. The rebounding brown bear Ursus arctos Sweden is monitored by two different systems, both relying on voluntary resources. Population estimates have been calculated using Capture-Mark-Recapture methods, based DNA-based scat surveys five six Swedish counties with established populations. A total 1,358 genotypes were identified DNA extracted from collected scats. An independent ongoing programme, Large Carnivore Observation Index (LCOI), was initiated 1998. LCOI uses effort-corrected observations bears moose Alces alces hunters during hunt (> 2 million observation hours/year) has shown a good correlation relative density method. From this, we period 1998-2007. Using an exponential model, estimated yearly increase p...
