In this episode of the Think Wildlife Podcast, we travel to the frozen frontiers of the Arctic to uncover one of conservation’s most inspiring success stories — the revival of the Arctic fox in Svalbard and Fennoscandia. Host Anish Banerjee is joined by Nina Elisabeth Eide from the Norwegian Institute for Nature Research (NINA), who shares her remarkable two-decade journey studying and protecting wild canids in one of the world’s harshest environments.

Once reduced to barely 40–60 individuals, the Arctic fox population in Scandinavia teetered on the edge of extinction due to overhunting, climate change, and competition with red foxes. Through dedicated efforts in wild canid conservation, the population has rebounded more than tenfold to nearly 600 foxes — a triumph made possible by scientific research, adaptive management, and international cooperation.

Nina describes how her PhD work in Svalbard explored the ecology and spatial behaviour of Arctic foxes, revealing how these resilient predators adapt to shifting prey availability across coastal and inland tundra. She explains their extraordinary biological adaptations — from thick fur and fat reserves to metabolic slowdown — that allow them to endure months of Arctic winter without freezing even at –40°C.

The discussion delves deep into the innovative conservation measures behind the Arctic fox’s recovery:

Supplemental feeding stations strategically placed near den sites to enhance pup survival and reproduction.

Red fox control programmes that limit competition in critical Arctic habitats.

A successful captive-breeding and reintroduction programme, which has released over 460 foxes into the wild, boosting eight distinct sub-populations across Norway, Sweden, and Finland.

Long-term genetic monitoring, collecting nearly 800 DNA samples annually to track individuals, maintain genetic diversity, and assess the success of reintroduced foxes.

Beyond the science, Nina reflects on the emotional highs of conservation — from the joy of releasing foxes into the wild to the collective sense of achievement when a once-critically endangered species begins to recover. Yet, she warns that ongoing threats like climate change, habitat fragmentation, and red fox expansion still pose challenges to the long-term survival of Arctic biodiversity.

This episode offers a rare glimpse into the perseverance and ingenuity that define modern wildlife conservation. It highlights how collaboration between scientists, governments, and local communities can restore fragile ecosystems and preserve the delicate balance of Arctic biodiversity.

Join us to learn about the ecology, behaviour, and conservation of one of the Arctic’s most charismatic species — and what its recovery means for the broader effort to safeguard biodiversity hotspots under a changing climate.

Whether you are a wildlife enthusiast, conservation biologist, or simply someone inspired by stories of nature’s resilience, this conversation captures the essence of why protecting wild canids like the Arctic fox is vital for the future of our planet’s biodiversity and nature.
