Seasonal migrations and space use of non hunted moose population in the Biebrza Marshes Poland
The Biebrza marshes are one of the most important refuges for moose in Poland, where since 2001 temporary moose-hunting moratorium is imposed. The Biebrza population numbers over 600 individuals and is genetically distinct from other populations in Poland. In 2011, we initiated a project on space use and foraging ecology of moose with the use of modern methods: GPS-tracking and DNA-based diet analysis. We immobilised 21 moose (11 females and 10 males) in January-March 2012, and fitted them with GPS-GSM collars (Ecotone, Poland). Collars collect 24 locations a day. Our preliminary results showed that in winter, moose ranges (MCP 100%) covered an average area of 12.5 km2 (range: 3.2 - 30.2 km2) and did not differ significantly between males and females. Mean daily movement distance was 1,68 km (range: 0.78 – 2.12 km). Collared animals utilised mainly pine forests. The majority of moose (67%) migrated a short distance (7.0 km on average; range; 3.3 to 18.8 km) in late March and April to the marshland. Spring ranges of collared individuals covered 16.8 km2, on average, significantly larger for males (25.6 km2) than for females (8.0 km2).
