Występowanie łosi Alces alces L. na terenie Lasów Rogowskich (środkowa Polska)
We reviewed all available historical data as well as recorded direct observations. This included data collected through various methods such as drive counts, night spot-light and thermal vision counts along transect routes, snow tracking, camera-traps and pellet group counts. Occurrence of moose and...
