For ecologists restoring the vast bogs of remote Karelia, wild reindeer are not just part of the environment but entwined with the ancient culture of the boreal forests

The Finnish folk musician Liisa Matveinen lives in a mustard-coloured house in Ilomantsi, 12 miles (20km) from the Russian border. Large books of folk songs line her walls. Sitting in her kitchen, Matveinen sings a about a humble hunter going into the woods to find reindeer.

The song tells us how they were “honoured” providers of food, clothing and a sense of place, says Matveinen, who is recognised as a doyenne of Finnish folk music.
