Arctic fox project

The Swedish Arctic fox project (Fjällrävsprojektet) is a research group in ecology at Stockholm University led by professor Anders Angerbjörn. We study the demography and genetics of the arctic fox as well as its interactions with other species in the mountain tundra ecosystem. The swedish arctic fox project is part of the EU interreg projects Felles fjellrev II and Arctic fox together. Felles Fjellrev II is a conservation and monitoring program in colaboration with the county board administration in Jämtland, Västerbotten, the countys of Sør Trøndelag, Nord Trøndelag and Nordland as well as Norsk institutt for naturforskning (NINA) the Norwegian Environment Agency and the World wildlife fund, WWF.

Arctic fox together is a collaboration between Stockholm University, Norrbotten county board administration, Norsk institutt for naturforskning (NINA) and Metsähallitus (Finland).

Tält i fält

In July, we visit arctic fox dens in parts of the Swedish mountain range/tundra. We do this to see if the dens are inhabited. At the same time, we conduct extensive surveys of small rodents and birds because their presence and abundance are very important for the arctic fox and our understanding of the Scandinavian tundra ecology.

Updated progress report (Swedish)

Karta över årets kullar 2016

Sommaren 2016 föddes totalt 8 kullar i de svenska delarna av fjällkedjan. 6 av dessa föddes i Borgafjäll och 2 i Helagsfjällen. Inga kullar rapporterades från det tredje kärnområdet, Vindelfjällen, eller övriga landet.

Why we tag foxes

Märkt blåräv sedd genom kikare

To obtain a deeper understanding of the ecology of the arctic fox we need to collect information on an individual level. An ear tagged fox can be recognized in several hundred meters with a spotting scope. With no need to stress the fox. If we would not tag individuals we would lose the possibility to evaluate and improve the conservation measures that is carried out in order to save the threatened Scandinavian arctic fox population.

Regarding internship or research traineeship

Tent pitched in the mountain tundra

We get several questions regarding the possibility to make an internship with us. We are open to this but mainly for the field work which take place basically during July and August.
