As part of the state-sponsored program to restore Arctic foxes, Norway has been feeding the population for nearly 20 years, and the program has helped to boost the fox population from as few as 40 in Norway, Finland, and Sweden, to around 550 across Scandinavia today. “Without these conservation measures, the Arctic fox would surely have become extinct in Norway,” said Bjorn Rangbru, a senior advisor on threatened species with the Norwegian Environment Agency.
