Population monitoring of Gyrfalcon, Golden Eagle, Willow Grouse and Passerine birds
Chick production for Gyrfalcon and Golden Eagle. Population variation (indices) for Willow Grouse and Passerine birds. Heavy metal and Cs137 in plants and liver samples
Børgefjell National Park, 65 08 N, 12 50 E Dividalen National Park, 68 42 N, 19 47 E
Reproduction for raptors are based on registration of cicks production in 10 Gyrfalcon and 12 Golden Eagle territories in Børgefjell. Production and population indices for Willow Grouse are quantified by censusing permanent transects with pointing dogs in August (Dividalen and Børgefjell). Population indices of passerine birds are registred by point censusing of 200 permanent sites in each area (Dividalen and Børgefjell). The project also include mapping of heavy metals in selected componets in the food chain (e.g. plants, common shrew, voles, pied flycatcher, willow grouse)
The project is a part of the Norwegian 'Monitoring Programme for Terrestrial Ecosystems' organised and financed by the Norwegian Directorate for Nature Management.
