Climate drove the fire cycle and humans influenced fire occurrence in the East European boreal forest
Abstract Understanding long‐term forest fire histories of boreal landscapes is instrumental for parameterizing climate–fire interactions and the role of humans affecting natural fire regimes. The eastern sections of the European boreal zone currently lack a network of annually resolved and centuries...
