Almost three weeks of fieldwork in Canada are over. Together with colleagues from the Institute of Botany of the Academy of Sciences and J.E. Purkyně University, we sampled trees, seedlings, and shrubs at Mont Jauffret and Mont Babel treelines in the region of Uapishka, Northern Quebec. It was great to be back in remote regions of the Arctic after years of travel restrictions! We thank Interact for providing the funding and the staff of a local research station for their support and hospitality.
