Beyond cutely frolicking through meadows in Iceland and Scandinavia, arctic foxes are also aiding the local ecological balance in the way they keep house underground. Their dens are often a century old and topped with lush gardens and dune grass. The domains of arctic foxes are a splash of colour in an otherwise dull brown and grey Arctic tundra.
According to National Geographic scientists, these gardens create such a stark contrast on the tundra that scientists who recently published the first scientific study on the dens have dubbed the foxes “ecosystem engineers.”
